Improve the Performance of a Cheap 5 8GHz Cloverleaf Antenna with Two Simple Mods

Two simple ways to improve the overall performance of a 5.8GHz cloverleaf antenna, but both have very different effects.

Great info on the why on 3 blade, 4 blade, coax length!

[@startazz]

Hi Andrew and thanks for clearing that up about the three leaf and the four leaf antennas as i mentioned in the last video i think it was. ;-)

[@andrewmcneil]

Yes I remembered your comment as I was filming it :-)

[@franklee90]

Love those experiment !!

[@henriksegercrantz362]

Great work. Thanks!

[@highflowhighflow9896]

great to see nice results from little mods! i ordered a sector antenna for 2,4ghz , should be 17dbi, no special purpose for it yet but i find this kind of antennas very interesting and like to experiment, it use some kind of cones 8 pieces or so on circuitboard. I couldnt find more details. Maybe a thing for your next projects the make of those sectors / arrays of quads and other shapes combined. i made a 8-double bi-quad array which is about 1m2 in size years ago for the digital tv on the air , worked great but its down in basement somewere as we have iptv now.

Hi Andrew. I fly Quads and have made a pair of skew planar (4 leaf clover) antennas for my goggles. At the distances I am now flying from myself they are working as well as my pagodas, but I haven't really pushed or tested them to their limits. I am interested, as a hobbyist in being able to test my antennas so I can learn how to make them better. Do you know of any computer based spectrum analyzer software that would be affordable for a hobbyist? I have a RF power meter ( hobby grade) but that can only take me so far as it doesn't allow me to see if my antenna is tuned well or not, the way a spectrum analyzer would. Thanks for making these videos, this one especially! Sean

Any chance on modifying a AOMWAY FPV 5.8G helical antenna to get to actually work? Thanks really enjoy your videos.

[@fizziergaming]

great videos sir i had a question how we make a loptop wifi card into usb adapter because the laptop wifi card is easly find from scarp and offcurse the alpha and tp link adapter is expinsive

[@TheMadmacs]

interesting stuff, i crashed damaged one of those cheap antenna and ended up making it into a 3 leaf antenna, i made a very average job of it and it still worked as good as the 4 leaf. i wonder if it is worth doing this to all my quad 5.8ghz antennae ?

[@freefilms10000]

Andrew,do you have more than one Alfa installed on your pc and if so, how did you do the second?

[@onedayillpay]

Can you put some of your antennas on this and shows us what a good results look like.

[@sipansibabdreddknot5179]

hey andrew is this mod applicable in your biquad yagi, yagi's or panel antenna for transmitting? and would it be improve it?

[@neodiy]

How can i purchase these antenna from you...and what is the best antenna for 2600 Mhz 4G?

[@MrApache64AH]

Hi Andrew, great video, but what happens if you combine the two mods?

[@andrewmcneil]

Hi Yusuf you don't need both as they both do the same job

[@ellisgl]

andrew mcneil the redundancy dept of redundancy wants to know.

[@lukearts2954]

andrew mcneil I'm with Kenneth. Since the stopper mod really flattened it out, maybe the loss of bandwidth you got from the length reduction is countered by adding a stopper to the shorter antenna.

[@jjssbailey]

Hello Mr. McNeil, And can you tell us viewers what the block is called that the antenna is attached, I assumed the tap is attached to the sweep receiver for reflected signal, is this correct?

[@andrewmcneil]

directional coupler www.techopedia.com/definition/18885/directional-coupler I will make some videos in the future about all the test equipment I use.

[@jjssbailey]

Thanks, site bookmarked.

[@19rocket64]

How did you determine the 12mm distance? I want to apply the same to 2.4ghz.

[@andrewmcneil]

I used the info from the pagoda antenna and the 12mm is less than a ¼ wavelength so it makes sense otherwise it will start to radiate after the stopper. I will look at 2.4ghz but at a guess and it is a guess, you would place the stopper around 23mm and the stopper would have a bigger diameter but will have to test.

[@peterwoo2489]

Does the distance between the end of the antenna and the stopper matter?

[@andrewmcneil]

I have not tested it just used the measurements from the pagoda antenna but it makes sense to have the distance from the stopper to the elements at just under a 1/4 wavelength otherwise it will start to radiate after the stopper

[@yourstudent445]

Make video on yeagi Antenna?

[@andrewmcneil]

Do you mean yagi? I have made quite a few past videos.

[@northwales1000]

I do like these videos, but 3 minutes about a washer. Far easier to use school compass or scribe divider.

[@thirdfakeofmoon7157]

Can we have a discord server ?

[@andrewmcneil]

What is a discord server?

[@thirdfakeofmoon7157]

first of all I LOVE YOUR VIDEOS SO MUCH !!! AND THANKS FOR COMING BACK And you can check out discord here discordapp.com/ or just simply google discord it's a platform where you can create a server , and then add rooms to the server with different topics , its very popular :) and its very easy to use , :)

[@lukearts2954]

he means a chat server, like the old inter relay chat used to be. It would be better for Q&A, but I'm not sure that's what you intend to do with your channel. You'll end up being a free teacher, or the point of reference for a knowledge sharing community. A very interesting concept in its own, and definitely worth being created, but like I said, it might be outside the your scope (pun intended) ;)

[@thirdfakeofmoon7157]

exactly :)
