[@AndreasSpiess]

You are right. Sorry for that

[@RambozoClown]

Your right or my left? What do you expect with both pipes on one side. ;)

[@MrCareyer]

Hi Andreas, you can also twist a copper wire with a cordless drill. Clamp one end into a vice and attach the other end to your cordless drill. Then give it some hundret Turns. The wire gets straight immediatly and becomes incredibly stiff. Cheers!

[@AndreasSpiess]

I did not know that. Have to try it once.

Very nice video and very smart the gags, Andreas. I'll see you next video!

[@AndreasSpiess]

Thank you!

[@linuxranch]

Andreas one trick you can use to work harden wire is to loop it around a parking lot bollard, and back to a trailer hitch on the back of a car. If you purposely nick the wire with a wire stripper, one wire guage smaller than the wire's actual guage, you can encourage the wire to break at a place of your choosing. Then by just letting the car drift until the wire breaks, you can control the degree of work hardening you get.

[@AndreasSpiess]

Interesting concept! Thanks.

[@AlexKite68]

Hi Andreas, Thank you for your perfect lessons! Awaiting for new episode - or are you on vacations this week? Please make the lesson about designing and ordering a customised PCB for ESP32, with soldering the components on the facilities of the manufacturer of the PCB. Also please make the lessons about programming new features of ESP32, such as multiple ADC, BLE, RTC etc :) And again thank you for your brilliant sense of humor!

[@AndreasSpiess]

Thank you for your comment. I was on holiday, yes. There are tons of PCB videos (because JLPCB paid some KZbinrs). So, I will not add one. I will continue to cover the ESP32

[@biezitis]

Very useful and cheerful video. I've been following your videos for the last couple of years. Their are among my favorites on KZbin. Keep that way and good luck!

Andreas Spiess you now have a Phd for building antennas. Powerfull Harley Davidson 😀

[@AndreasSpiess]

The Harley is probably not very powerful compared to modern Japanese bikes. But it is louder ;-)

[@Richardincancale]

Hi Andreas - did you check again with the VNA after installing inside the plastic pipe to see if the characteristics are changed by the proximity of the dielectric?

[@gijsmos1204]

LoRaTracker commented on this effect in www.thethingsnetwork.org/forum/t/the-big-and-small-antenna-topic-part-1/7880/506?u=gmos . Putting the antenna in plastic pipe messed tuning up considerably.

[@AndreasSpiess]

When I showed the VNA I showed the influence of the plastic around an antenna. And the link below to loratracker is a good one.

[@Justin-bd2dg]

This is a very handy trick to stripping the insulation from house hold wire!!

[@AndreasSpiess]

True!

[@Liberty4Ever]

I just spent $154 on Rokland today, buying four antennas (3 @ 8.5 dBi, 1 @ 5 dBi) for a family off grid texting network that I'm building. I'm an amateur radio operator so I felt guilty not building my own antennas. I probably should have watched this video first. The nodes are solar powered and mounted on roofs with thick wall PVC pipe, so a collinear antenna could be hidden inside the PVC pipe.

[@AndreasSpiess]

Indeed, a lot of people started to build antennas after these cheap VNAs were available.

[@anullhandle]

I like your way of work hardening the copper. With the drill method and a thickening wire I wonder if the major difference is a slightly wider usable pass band? I suppose you could just pass the pvs thru the loops to support it for indoor use.

[@AndreasSpiess]

Maybe the range would be wider, I did not try. Fabien's simulation was based on the 1.4mm wire. And I want it for outdoors because it does not make a lot of sense for me to use it indoors.

[@drusha]

KZbin needs 'mono' button

[@EgonSorensen]

Great video on antennas. I noticed you wound the antenna turns clock-wise, and not counter-clock-wise as shown on the schematics. I know that some antenna types must have both CW and CCW, to balance the antenna. (Transmission line, impedance coupling) I suggest you try the CW-CCW combo, until you get outdoor'able weather again. This might even make it fit in your pipe.

[@AndreasSpiess]

Thank you for the idea. I will try that.

[@DougHanchard]

At least you were not given the option to take the Red Pill and have to make the attempt to chase the White Rabbit.... Very ambitious project. Building these types of antennas is not for the faint of heart if one requires perfection - which these ones demand.

[@AndreasSpiess]

It was just a try...

[@DougHanchard]

Andreas Spiess I really enjoy your engineering prowess. You make people think and command within themselves to experiment using sound scientific principles; propose theory, test through experiment; determine results to verify hypothesis in a transparent manner for peers to reconfirm. Without this process, we would not have the scientific laws we rely upon daily. You illustrate all these steps beautifully and have some great fun in the process. +1

[@R73CH]

Remember to measure the antenna after mounting it into PCV tube. The permittivity of the tube can affect the overall performance at these frequencies.

[@AndreasSpiess]

You are right. I discovered this effect in my video about the VNA. The effect can be quite big.

[@texhow1]

I was told by a Feranti technitician not to use black or dark tubing for covering antennas as the tubing contains Carbon which is Conductive & screens/blocks your antenna from outside signals.

[@fute27]

I'm curious to see a chart of comparison with home made antenna and high gain from Aliexpress. ** I just ordered that exact same antenna just before you posted your video !! aaarhhh. now that you mention your not using it anymore I'm really curious to see those plugged into your full size spectrum analyse.. I'm waiting for the white high again (that you show in this video) and the black RAK one (in your range testing) a comprehensive video on antenna testings, comparison and evaluation would be VERY nice !! :) Thanks Andreas keep up the good work !

[@AndreasSpiess]

I am not sure I will do a lot of antenna testing. Maybe somebody else does it. I made the beginning and provided the needed tools.

[@PhG1961]

Awesome video ! I like the antenna constructions and especially the Harley method. You should deposit a patent for that method and antenna product.

[@AndreasSpiess]

Maybe a little expensive if you do not happen to have a Harley in your garage...

[@PhG1961]

I happen to have a BMW GS, will this also work ? If not, then I need to buy a Harley...

[@AndreasSpiess]

A Harley is always good in a certain age ;-)

[@PhG1961]

The thought already crossed my mind....

[@andreisima1977]

Will this work with a Suzuky GSXR? Or shall I experiment with feeding the blue pill to the wire. Also I have black isolated wire not blue. Will that effect my motor that is mounted on the bike? :-) Keep up.

[@AndreasSpiess]

As a Harley owner I cannot imagine that it will work with other bikes ;-). And please keep us updated with your blue pill experiments. No details, of course.

[@SteveWrightNZ]

Looking forward to the antenna comparison

[@AndreasSpiess]

We will see when I find the time. Maybe somebody else does it?

[@gte24v]

Hi Andreas, interesting video as always. You might try adding the tube anyway, as I believe it will change your tuning a bit. Years ago I built an axial mode helix antenna (from the excellent Kraus book) for 1691MHz and found that to get the tuning correct, I had to remove the tube I was using as a former for the semi-rigid coax cable I used for the element. I was at the time sure that the arrangement could be persuaded to resonate at the correct frequency by varying the spacing and possibly diameter but I didn't have the time or modelling tools to go there. I would be interested to know if this makes a difference on the elements you have already built and tested. By the way, a pair of axial mode helix antennas combined using 75 ohm stubs gave over 18dBi gain but was also over 3 feet long. Kind regards,. Ian Till.

[@AndreasSpiess]

You are right. Plastic tubes, as well as all other geometries, change the center frequency a lot and the antenna has to be tuned with everything in place. I will experiment a little more an maybe come back with another video in the future.

[@norm1124]

[@makimcleary393]

Ich arbeite mit 8-12GHz-Systemen... Furchtbar. XD

[@squalazzo]

an easier method to stretch wires is to "drill" them: just fix one end to something, then put the other end into a drill and slowly turn it :)

[@squalazzo]

kzbin.info/www/bejne/mGWQgnljjLd5oLM

[@squalazzo]

thingiverse link brings to a 404 page

[@AndreasSpiess]

The link should work now. Thanks for the info!

[@AndreasSpiess]

Concerning the other method: Great! But it looks like the wire gets shorter (and thicker). So you probably have to start with a thinner wire if you want an exact diameter at the end.

[@squalazzo]

yeah, i think you're right :)

[@ardufpv4373]

I have to admit that I hit the like button before watching the video.

[@AndreasSpiess]

That is how we like it. Thank you!

[@ingmarm8858]

It will be interesting to see the amount of detuning that the PVC causes (it will change the antenna characteristics).

[@AndreasSpiess]

I showed that effect with another antenna. It was quite huge.

[@davidriley7659]

enjoyed the video as always andreas. Just an idea, the loops of the new antenna might be bigger than the outside of the first pvc pipe. then just run some electrical tape at certain points.... maybe?

[@AndreasSpiess]

My initial idea was to protect the antenna from the influence of the environment. But maybe it would be possible to protect it with electrical tape.

[@davidriley7659]

I had a think about this. I "think" they use self fusing silicon tape in the industry, and wind up from the bottom. Could be wrong. I'd just grab a scrap piece of heat shrink tubing. Anyway, just didnt want you stuck buying a piece of tubing for no reason.

[@Stimpofff]

Try out J-pole antenna ;-) size to performance ratio is really good. It is also very easy to build.

[@AndreasSpiess]

Good idea.

[@TheSadButMadLad]

Copper hardens when worked. As for support, how about having the copper on the outside of a tube which is 28mm OD?

[@AndreasSpiess]

I wanted it inside to reduce the influence of the environment.

[@makimcleary393]

Working the wire also increases the stiffness of "the other wire" XD

[@101jtag]

[@AndreasSpiess]

Yes, but I had to play with the distance between the in and out of the loops

Man and women are different. See here: amzn.to/2uXi5UQ. Mr. Gray got rich by writing this book.

[@ristomatti]

Could you add a link to the connector used with the antenna? I found male SMA connectors only with pins on the base. There were a lot of female SMA connectors available that otherwise looked similar.

[@AndreasSpiess]

Done.

[@Simon_Rafferty]

How do you rate your N1201SA Analyser? I have a RigExpert AA-1000 which has been pretty good - but yours is 1/4 the cost!

[@AndreasSpiess]

I made a vdeo about that topic. It is ok to test our antennas.

[@lshkim]

Hi Andreas, thanks for the great content! I do have a small question though. I'm in the US and planning to use solid copper electrical wire for this purpose. Is the diameter of the wire important? I have access to 2.053mm, 1.628mm, and 1.290mm diameter wires.

[@AndreasSpiess]

The diameter is not important for small power. In general you should get a broader bandwidth with thicker wires.

[@peterdkay]

Love your series on antennae. BTW That was all in MONO. Not nice when listening with headphones.

[@AndreasSpiess]

I screwed it up. Sorry for that.

[@TMS5100]

stretching copper work hardens it, which is why it becomes stiffer. btw it's wrong to say it's "resonant". it is impedance matched, not "resonant". resonance is completely different parameter, where reactive component is 0, e.g. X=0 or +j0.

[@AndreasSpiess]

I am not sure Wikipedia agrees with your very narrow definition of resonance.

[@TMS5100]

www.k0bg.com/myths.html#resonance kzbin.info/www/bejne/bmKYpph9hb9_gqs simply put, resonance is where reactance is 0. resonant frequency of an antenna may not be the same as the frequency of the best impedance match! on your N1201SA, antenna is resonant when X=0 (reactive component). And best impedance matched when R=50. always remember, RF is witchcraft and sorcery.

[@giteart]

Just an idea, why not leave the copper wire inside the original insulation of the cable and just somehow stick it to a piece of wood so as it keeps strait

[@AndreasSpiess]

Also a good idea. But not as spectacular ;-)

[@electronic7979]

Useful video

[@AndreasSpiess]

:-)

[@paullacatus8975]

Excellent video ! Like very much your American tools . Do you know something about the dielectric characteristics of PLA in high frequency ? Seeing your video I was thinking to 3D print some pieces for the loops and leave them on the antenna. PS. Your video does not have sound on smart tv

[@AndreasSpiess]

1. The sound is only on one channel. Sorry, I screwed it up somehow. 2. No, I do not know the behavior of PLA on high frequency.

[@paullacatus8975]

Only the Harley is stereo :)

[@daque1960]

For your consideration google c”opper clad steel antenna wire”. Due to skin effect only the outer surface needs to be copper.

[@AndreasSpiess]

Thanks for the hint. I did not know it exists. But it seems to be very difficult to bend...

[@emekae330]

Thanks Andreas for the great video. I could see that you are planning to use a grey pvc pipe to house the antenna, and I recall having issues with attenuation from grey pvc when I used it on my antenna design some years back. Do you have any concerns about this?

[@AndreasSpiess]

I assume it will shift the resonance frequency. Which has to be compensated by the design. I do not know the dampening effect of PVC.

[@emekae330]

I was referring to the effect of grey pvc vs white pvc. White pvc is more suitable for rf antennas as some grey pvc could contain pigment compounds that could significantly attenuate RF signals.

[@AndreasSpiess]

Now I got it. Thank you!

[@texhow1]

We were told by our radio club secretary who was a Ferranti Tecnician by trade never to use black or dark tubing for antennas as Carbon is used in its production which is conductive so it could screen or block signals reaching the receiving elements.

[@FilipeNeto616]

Putting it in to the PVC tube will have any downside on the frequency resonance? Hope not, or you'll have to tune it again. Whenever you can, could you please do a follow-up video with testing the new antenna?

[@AndreasSpiess]

You have to tune most of the antennas again if you put plastic around them.

[@FilipeNeto616]

Andreas Spiess that's what I thought since I've saw a video of you when you opened and cutted one of the smaller ones

[@itsy6703]

Hi Andreas I build this antenna twice and every time the best frequency was about 850Mhz. I could tune it a little bit but best frequency was never higher than 859MHz. So what can I do now or what did I wrong?

[@AndreasSpiess]

These collinear antennas are not easy to tune. I tried to change the different things until if was ok. Only millimeters matter

I tried building a 8-element coli for 1090 and failed, I used the Coax-Cable build. Discone worked fine but couldn't compete with default whip, and due to lag of skill, soldering was a mess. Still want to do a quadrifilar helix for NOAAs

[@AndreasSpiess]

Building antennas never was easy. Especially complex ones. Needs lots of experimentation.

[@W9HJBill]

What if you use a larger Harley to stretch the wire? Say a Road Glide Ultra with a 103 CI engine and a Stage 2 kit? :D

[@AndreasSpiess]

Mine has a 103 engine, too. But less weight, of course. And no kit ;-)

[@joostluyten_ON3JT]

Hi Andreas, can you or someone else help to understand a small detail? I see this returning at designs for ADS-B antennas too. The collinear is made up of three parts, to start with a half wave. As a fellow ham radio operator you know that a half wave at that feedpoint has an impedance in the region of 2500 to 4000 ohm. So I must missing a detail why those designs connect a 50 ohm coax directly to a high impendance. Clearly it works, but I cannot figure out why :-) Some bright light around?

[@AndreasSpiess]

Unfortunately, I am no antenna designer. Like you, I have no idea how they work. I can just measure if they work :-(

[@joostluyten_ON3JT]

Maybe someone of your subscibers knows the answer, I'm curious :-)

[@jurgenmiemer3772]

Collinears I know have 1/2 wave stubs (coils) and 1/2 wave segments. To match 50 ohm they start with a 1/4 segment. They have no stub on the end. This one has 1/4 stubs and 3/4 segments. Wich I think should work, as it is together also a full wave. Maybe the 1/2 wave segment on start combined with the shortened segment and the stub on the end matches it to 50 ohm? But as far as i know ' 1/4 segment + 1/2 stub + 1/2 segment ' should do the job with 7 dBi gain at half of total length. To reduce diameter the stub can have 2 or more turns. Manny car antennas for 70, 35 or 17 cm are built this way. Maybe someone can confirm ?

[@donpalmera]

For anyone that doesn't want to build one there is a guy on ebay that'll build a tested collinear antenna with a center frequency of your liking.

[@AndreasSpiess]

Interesting. Do you have a link?

[@AndreasSpiess]

[@Richardincancale]

Onur Akarsu I’m not Andreas but I did a study for a client recently... We concluded that LoRa is great where you know in advance where sensors will be - you can easily as economically extend the network if coverage is missing. Where you need mobility and can’t guarantee where the sensors will end up then NB-IOT has an advantage of wide area coverage. If really far away places need to be covered (oceans, deserts) then satellite systems (like Orbcomm, Inmarsat) are needed. Caveat - this is a 12 page conclusion compressed into 3 sentences.

put one end of the copper wire in your battery drill and the other in a vice and lightly pull and spin the drill. the wire gets stiff and straight. you save 30000+ euro :-D

Andreas Spiess Thanks for the reply, Andreas! Yes, I agree. And the definition of 'icon'. ... Something only fit to sit and look at! Just teasing, sorry! I love your videos, and am learning heaps. Thanks. 😋

Almost sh!t myself when you start the bike! Suddenly STEREO

Harleys are always stereo! Sorry for the mono parts. I screwed it up.

"First world problem" The video is still useful and informative!
