You build the antenna yourself to learn how antennas work (and save money in the process). That is what this is about. Those who buy "off the shelf" really do not learn anything regarding Amateur Radio, only create excessive cost and no knowledge regarding antennas as a whole. We can try to build our transceivers and do a pretty good job of it, but those who build antennas really know radio.

A friend of mine built one of these. This is only based on a test of one antenna. I measured performance in a clear open area. Since the intended use was hidden transmitter hunting, my only concern was the antenna pattern. I found two important things with the antenna brought to me: 1.) It had terrible common mode on the coax. I could touch the VNA analyzer case, or slide my hand along the coax, and see a fairly large change in impedance. 2.) It had generally poor directivity in the 2M Ham band. It lacked a good deep null off the rear. It actually seemed to have better directivity on the weather band than2 meters. I did two things. 1.) I altered the spacing. We just swapped the director and reflector around on spacing so the reflector is wider spacing like almost all 3 element Yagis are. This improved the back null quite a bit. I made no efforts to trim elements, but suggested he make the elements slightly long in a future model so we could trim them in. 2.) I grounded the coax shield to the center point of the reflector. We had about 18 inches of coax spiraled around the boom to the hairpin match. This forms a high impedance on the shield at the hairpin. This completely eliminated the noticeable SWR changes as I moved my hands along the coax.

I built one of these over the weekend and it works very well. I got the SWRs down to 1.1:1 and instead of soldering the coax to the driven elements, I decided to use an SO-239 connector with 3 inches of wire for the center conductor and ground, each. My house is in a 100 ft valley (compared to surrounding terrain) and I am still able to talk to my brother 4 miles away on 1 watt of power. Also, I'm using RG-8X coax to connect to the antenna.

Michael, I watched this a couple times last night (friday.) I managed to copy a rough idea of this (2 meter, tuned with the nano) and made a contact 52 miles away with a UV5R, yes you heard that right, a little 3 watt radio. I think the real lesson here can bring up a multitude of topics which I will discuss with some other people soon here: hams have the privilege of building their own stuff, our signals can travel much farther, that topic of possible interference could possibly happen if it's zipping around the earth or bouncing off of things and lastly and most importantly never underestimate the ability of underrated equipment in the right conditions.

@tomperone93389 ай бұрын
Your build is very similar to the way I typically make them. I like to dip the ends of each element in that liquid plastic stuff they sell at hardware store for coating tool handles. It makes the ends more visible and prevents the ends from scratching or poking anyone. Also, I always put a cross on the director end as well. Once you’re close to a hidden transmitter, it’s often easier to zero in on the location using the null on the reflector end, so the extra cross allows you to hold the antenna ‘backwards’.
@jordanwosnick2 жыл бұрын
This is a very informative and clear video. I built this antenna with one minor modification -- instead of soldering coax directly to the feed point, I instead soldered an N-type socket, and use an N-type to SMA cable to connect to my HT. (I have bad luck when it comes to stripping and separating coax. My approach ain't pretty, but it works.) I also covered the tips (last 1/2 inch) of the elements with electrical tape to avoid cuts and scratches. Analysis with a NanoVNA showed my version had an impedance of 52 Ohms and minimum SWR of 1.1:1 at 148.5 MHz. The SWR increases rapidly from that minimum, but still seems reasonable within the 2-m amateur band. On 70 cm, the antenna has an SWR of 1.6:1 at 449 MHz. I'll try playing around with the spacing of the driven elements to see if I can bring the resonant frequency/ies into the right range.

I was able to receive voice from AO-92 (VHF downlink) and SO-50 (UHF down) loud and clear. However, it is not a magic wand! and I was NOT able to transmit successfully to a friend 1 mile away through medium dense forest/trees (this is not surprising). Without so many trees blocking, I was loud and clear TXing at 4 watts from 1 mile. Don't expect to beat the laws of physics or anything with this, but even without tuning you'll be able to recieve MUCH better than you might with the rubber ducky. Tune it for best possible TX capability! Thanks VBR for the awesome design! de N0CALL ;)

UPDATE: Picked up a MicroFox (15mw output) and built a couple of these using an active offset attenuator. I use them specifically to teach scouts for Merit Badge Requirement #9, partake in ARDF, but I also use it as a DEMO for a variety of youth events. I set the FOX a distance away, and show them how to use the setup. My attenuator offsets the main frequency by 4MHz, making it cleaner to find the fox. The original antennas still work, but I am building a couple more so multiple sets of Scouts can look at the same time. I also have a few full power HTs (6watt) that are crossband I have used for a greater distance fox hunt. However, this is still, as far as I am considered, the gold standard for the homebrew Yagi. It is simple, it is cheap, and it is fast to assemble. I used my NanoVNA and tuned it to 1.2:1 on 2Meter, and it was also 1.8:1 on 70cm I use it to contact the ISS Repeater and have had a QSO from FMo5 to EM26 through the ISS Repeater.

It is unfortunate public high schools have eliminated basic electronics shops along with wood, metal and auto shops. Thank you for the videos. I don't know anything about anything related to electronics. Can I ask why are the "elements" (?) cut at such a precise length? Why are broadcasts called "2 meter"? If an antenna element had to be exactly two meters would it matter if you took the two meter antenna and rolled it into a coil? There certainly is a plethora of panel antennas and antennas of every configuration. It would be nice to have an illustrated up to date book with photos of every sort of antenna with a paragraph of the name, type and function of an antenna. Satellite and other antennas are popping up everywhere.
@KB9VBRAntennas7 жыл бұрын
I'd agree with you that technical education is lacking in many high schools. Bucking the trend, our local high school just expanded its technical and industrial arts program. They did it in partnership with the area technical college. As for antennas, a 'field guide' of types of antennas would be really handy. I'll have to do some research to see if anything exists. What makes an antenna work is its resonance to a particular frequency. Radio Frequency energy travels in waves. When an antenna is resonant, it will easily transmit and receive the RF energy that is traveling at that frequency. That is why the elements of an antenna are precisely cut. These RF energy waves are described by the frequency they travel at, such at 146 MegaHertz, or by the size of their wavelength, like 2 meters. 146 Mhz is a frequency that has a wavelength of 2 meters. We could use a coil of wire to detect the radio waves, but fashioning the elements of the antenna in the style and orientation described in the video is more efficient than a coil of wire. This is a very simple explanation, but hopefully it answers your question.
@edwingdelgadodelgado62615 жыл бұрын
Short description... 2 meter refers to a frequency band where the "center freq" is around 146 MHz (144 MHz - 148 MHz, allocated by FCC in USA for ham radio).... the length of the electromagnetic wave used to transmist and receive is around 2 meters (some calculation required). In order for the antenna to receive/transmit efficiently their lengths must be precise (although some >5% tolerance is usually accepted). Antennas are some diverse and so many.... depending mostly on applications.... The American Radio Relay League (ARRL) is a good start to look for antenna books.... look in their site and in Amazon.

If you make a 3 element yagi and tune for the greatest gain, ignoring swr and f-b/f-s ratios, it might be possible to achieve 7.2 dbd gain, but if you strive for good balance in all those parameters, then 5-6 dbd gain is all you can hope for!
@KB9VBRAntennas7 жыл бұрын
You are correct. Since this antenna is designed for fox hunting, it's been optimized for a high front to back ratio, hence the higher gain and deep nulls to the sides. But a more 'balanced' antenna would have a little lower gain.

These DIY antennas are great for qrp camping or for use in direction finding fox hunts

The store here only had cross pieces in 1 1/2" and larger, they were tapered for drain purposes, not what we need. Oh, I'm KL4PR on the air, try DMR on Alaska statewide. Thanks.

I built this and got the swr down to 1.2, but I still can't get into any distant repeaters. It works with the more local repeaters, but so does the rubber duck.

What an awesome yagi, but i noticed toward end of video how the tape measure fluttered in the wind/breeze! Would this affect it's performance? Cheers! VBQ543 Mick

Nice video, and thanks for the quality J-Pole. I'm wanting to build a Yagi for the GMRS band. My question concerns the hair pin match. Is it only required here because it's a 2-meter build, or would the same apply to a GMRS build?

Love this antenna idea! Any thoughts on making a 70cm version? Or making this a dual bander by putting 70cm 90° off from the 2m elements?

Kids are wanting to try a fox hunt so we will be building this first. How narrow of a single azimuth would we be able to detect. Never done a fox hunt and wanting to understand how it correlates to map and compass navigation.

Nice job and handy video. I'm curious why you think that should only be able to handle around 10 watts. Your elements are large durable spring steel. Your coax should handle at least 100 Watts. Your hairpin looks sturdy enough to handle at least 50 to 100 Watts. Please elaborate.
@KB9VBRAntennas7 жыл бұрын
The hairpin match is made out of 20ga hookup wire, so it is pretty thin. There is probably no reason why you can't use it at a higher power level, but personally I've only used the antenna with my portable radios. My recommendation would be to try it at a higher power level and check for heating. If all is good, then feel free to use it at full power.

Hi Michael, Nice Video. I notice at the co-axial feed point to the driven element the loop of wire connects between the 2 halves of the driven element. I thought that would short out the co-axial cable. Can you explain - I may be dumb haha.

My concern as well.

Gonzo Buddy so is the “shorting wire” required? I can accept they are different, but can you tell us how and why? It still looks funny to me.

I'm not a Ham but seeking info for a directional antenna for different purposes. The measurements you gave were very precise. I'm assuming the antenna you built was designed for a specific frequency. Where can I find out how to change the measurements for a different (but very close) frequency? What kind of frequency range would this antenna manage? Thanks for the great video!
