2.4GHz & 5GHz Wifi Parabolic Dish Feed

[@ministeriomundialliberando8403]

Your projects are very professional and with technical criteria. I've done your extended range 2.4Ghz with the added load coil and it works. Thank you a lot.

[@andrewmcneil]

Your welcome

[@ministeriomundialliberando8403]

I wonder if at some time can you explain the antenna inside an ubiquiti brand 2.4 and 5ghz.

[@andrewmcneil]

@@ministeriomundialliberando8403 I keep searching for one at the right price but they are very popular and bids can go a bit silly.

[@ministeriomundialliberando8403]

Can't wait to watch, read, and listen to the follow up to this video!

[@DavidLopez-bz4rj]

Andrew, there is an interesting antenna you can easily build for these frequencies, the double rhombic antenna (or simple). Only some wires and a resistor (and maybe a balun). Can be made on a carboard and turned to desired polarization.

[@MariusBartkevicius]

Andrew, Could I recommend the plumbing hardware for housing elements? It is not terribly expensive and is made having water tightness in mind. Please have in mind that there are different plumbing parts for indoor and outdoor use (temperature range, UV resistance etc)

[@freefilms10000]

inside the alfa rod antenna is is simple dipole covering both frequencies which you can use with your dish.

[@bastadimasta]

Hi Andrew. I am duplicating your work for hobbying purposes. Doesn't soldering the rods on the top side would give a better performance because of the larger and uninterrupted resonance cavity at the bottom? I have another question. Are we keeping the impedance of the strip at 6:47 to 50 ohm. If so, it should have been 3.4 mm wide. If not, can you help me to understand. Thank a lot man.

[@andrewmcneil]

What do you mean by rods?

[@bastadimasta]

@@andrewmcneil you called them rods if I remember correctly. The bronze wires with 1.6 mm diameter that soldered to 20x20 mm pieces. Thanks for answering.

[@andrewmcneil]

@@bastadimasta Right, I understand, they would make little difference to the performance of the antenna but moving them to the outside would lengthen the transmission line and could change the operating frequency.

[@bastadimasta]

@@andrewmcneil Thanks. I took a Signal course in college, and don't know much about anything else. Can you please tell me about if we are keeping the impedance of the transmission line to 50 ohm?

[@andrewmcneil]

@@bastadimasta Yes 50 ohm is achieved by the width of the feed lines to the 20mm panels and matched with 50ohm coax

[@StephenCashmore]

I was using satellite coax and f-connectors, but what sort of loss would I get as it not designed for 2.4gig Wi-Fi directional antenna, I have to say I was getting reasonable result. f-connector to sma adapter at the router end. But I thought it would be better than the cheap co-ax that they sent me with the directional antenna.

[@MuSic-kl3pd]

that was very nice antenna , like this video 👌 keep going !

[@MiniLuv-1984]

What a great channel - for me at least! Thanks Andrew, nice design and nice results!

[@dannyzuko7521]

Great videos. Any chance you'll be doing biquad or patch antennas for 4g Band 20, 820mhz. Need to upgrade the bunny ears on a TP-LINK 4g sim router. Cheers pal. 👍

[@paul_daniels]

Great video Andrew. I often hear you say you designed the antennas you build and I was interested to find out how you come up with the dimensions etc. I've designed/modeled/built a fair few hf/vhf/uhf antennas with MMANAGAL but I have no idea how to do something as cool as a panel antenna.

[@markspc1]

Great video Andrew. I was wondering how does this flat plates design compares with your previous Biquad design of Oct 31, 2021 ? Thank you.

[@sgalien6661]

Hi Andrew, i cant find copper here in Singapore so could i use aluminum or silver sheet as i have a mini electic smelter as i can cast my own sheet?, (i cant melt copper or i would do that and not have asked lol).

[@alaanoor3679]

Hello Andrew, May i ask you for a video about the RCWL-0516 Microwave Proximity Sensor? if we can hack it to be directive or more sensitive , or at least just your thoughts about it

[@bossmarktv3629]

Hi andrew can i habe the list your using on that tutorial.. please

[@jukkapekkaylitalo]

Am right to think that those rods are for 2.4 Ghz and patches for 5Ghz?

[@sgalien6661]

I love this channel, and ant theory lol. You're the type of old-school chap that knows how to make things and how they work too. Can you make an ant array? do arrays need circuits/ electronics? basically, id like to use many high dbi ants to get great range and signal strength. Thanks your friendly fellow brit overseas in Singapore :)

[@andrewmcneil]

I appreciate that!

[@herdmay1]

Thank you for making back to back videos on parabolic reflector antenna feeder , I was looking for few ideas. I wanted to know if the gain of feeder increases the overall gain of the antenna ..

[@lustrup]

The antenna gain is in the parabolic dish gain (not the feed gain). You can NOT just add feed gain with the dish gain! The feed is for focusing the RF to iluminate the dish with minimum spillover at the edges.

[@douglasfurlong1]

if you made that copper piece more bigger would it get better reception?

[@S4TECH1]

Interesting video thanx can u give us schematic and measurements of the feed ….

[@sunandajayakoday5418]

Interesting video Andrew.Thank you.

[@JasminSuljic-q9f]

Hello Andrew, Question please, i build one of that antenna.Can I fix that feed instead of LNB to point to dish?The dish is 90 cm square.Or must it be exactly in the middle of dish.Thank you forwardly for answer.

[@maxmor383]

Excuse me, is it okay if i connect two cables in this board? Two cables to be attached to the device. Thank you

[@chazlabreck]

I have seen the yagis done with circles is there a reason they need to be square? and can something similar be made with four round driven elements? and a round back? would be really curious if that would work? I have a hole punch that looks just about the right size given the area.. also could it be done with copper tape on plastic cd covers? supper cheapskate antenna ..i have old satalight dishs.

[@brucekolsky7892]

In your video "2.4GHz & 5GHz Wifi Parabolic Dish Feed" you left an unexplained gap between the pigtail and the antenna ... visualizing, I assume the short coax that you soldered to the antenna and the pigtail are actually one and the same in the end product???

[@jmunozar]

Hey Andrew, thanks for these videos; quick question: Does thickness of the copper plates affect performance on the antenna?

[@andrewmcneil]

You can get more forward gain using thicker material for the reflector. (front to back ratio)

[@jmunozar]

@@andrewmcneil thanks for the reply!

[@xsirfr1958]

@@andrewmcneil Thicker material should increase the bandwidth too, no?

[@andrewmcneil]

@@xsirfr1958 Not on this type of antenna no as it radiates in a different way to say a biquad or dipole.

[@wenjhondavin3548]

I wish you could teardown or build a parabolic dish feed for cross polarized 4G antenna.

[@papagayoR]

Sir, could you modify this project or send a draw, with two ports for use in N78 3300-3800 MHz area, for dual port TCL N78. As Vodafone in my area supports this freequency, and router ports need to be both on N78 antenna. Any other suggestion is welcome. Thank you very much. Really good work.

[@junpauljumalon9843]

Hi Sir. Is it possible to connect two antennas (identical/or not). If yes, what connection, series/parallel? Using sma splitter? Since my neighbor has same antenna as mine and they no longer use it. Haha. Highly appreciated if you could produce a video with this idea. Thanks

[@andrewmcneil]

Yes, absolutely but you would get a small amount of loss.

[@AbdulRahman-sv6xd]

I have 2.4ghz WiFi router Can I use this as an external antenna ? I need answers please ❤

[@sgalien6661]

Hello again Andrew, how much better do you think an ant like this or a single 2.4 or 5ghz patch ant made from silver? basically, I'm thinking of smelting down some old silver and casting out the sheeting, erm how could i soldier silver parts together lol no idea but i can make the raw material so i thought it was a silly question but a fun one worth asking. Regards Chris A

[@andrewmcneil]

I have made a dipole out of silver just for fun. Although silver is a better conductor than copper you would not see a difference in the real world.

[@wangbu8869]

Did you sell the design? Here in Philippines they make just like this and sell for 3k

Excuse me Sir. Can I ask what's the measure of every element since in the video you say it is 20mm×20mm but, on the art sheet I see a scale of 30mm×30mm? Thank you in advance.

[@andrewmcneil]

The scale is so you can check your printer has not rescaled the artwork. Measure the artwork.

[@ministeriomundialliberando8403]

@@andrewmcneil So, does it mean that the real measure is 20mm×20mm, right?

[@gigigigiotto1673]

How could i tune this only for 2.4ghz? All the 4 elements seems to have the same spacing and sizes, maybe i missed something in the video. (i'm a big noob in antennas btw)

Hey Andrew, please guide me to learn what you do.

[@theking-lr2yy]

What is the truth about making our antenna with a satellite dish and a pringles?Is it possible to modify statilite dish and apply this method, will it really work?

[@timfreeeed]

when i want to do this with a n78 band 5g these are just perfect quads, yes? do you have a schematic or calculator with the relevant spacing? :)

[@jayriecoboyjames]

What happened if i build it bigger ? Because i live far away fron town and i have a crappy 4g and sometimes a 4g+, i was hoping i can build it bigger to get a better signal, is it possible ?

[@andrewmcneil]

Bigger changes Frequency not gain

[@jayriecoboyjames]

@@andrewmcneil i see.... how to get more gain like i lived 13 kilometres away from town area which has a better reception

[@Watchyn_Yarwood]

I am curious about the parabolic dish you use. What are the dimensions? Is it a satellite TV dish or a WiFi specific dish?

[@ministeriomundialliberando8403]

Can I help with your answer? No, the parabolic is just this, you can use it wherever you need as long as it fits to your purpose.

[@beansfoundhere]

I don't understand at all why this is resonant at both those frequencies, but it's great. Maybe something to do with 1/4th and 1/8th wavelengths seeing as 2.45 is almost half of 5?

[@andrewmcneil]

That is my thoughts as well although I am unsure of the theory behind it, I just know it works.

[@MrBesmir7]

Could be wifi adapter itself automatically put lc curcuit in resonance

[@abojavar]

Hello, does this work for an antenna to boost the signal of the 4G router?

[@SimonShaws]

Do you mean 4G reception? No. It's designed for 5GHz wifi and 2.4GHz wifi. Unfortunately patch size for 4G can be up to 20cm square.

[@abojavar]

@@SimonShaws How can I design an antenna similar to this that receives a 4G network

[@SimonShaws]

@@abojavar would recommend a biquad design if you want for parabola? Or a yagi for directional. You can buy a cheap one on ebay for correct frequency but the cables usually cheap and nasty. Swap for shorter cable that is good quality. This assumes router has antenna connector.

Its probably metalised somehow or it wouldn't work. I have used sat dishes but they are trickier to aim as the reflection points offset. Sorta like \_ with focus near the bottom.
