Dual Polarized Biquad Antenna
Вставка
- Опубліковано 19 тра 2015
- In this video I show you how to make a biquad antenna that works in the horizontal and vertical simultaneously. This can be of benefit if tracking a constantly shifting object such as a quadcopter. It is also important to note that although the elements in this build are circular (one full wavelength) the biquad still propagates as a linear polarized antenna.

Andrew your the best in the world. Built 6 of your antennas. And the Biconical 2.4 ghz is my favorite.
Top drawer as always - and good luck with the shop. Deserves to do well. Have built several of your aerials and they perform and look great.
filmserve My pleasure, thanks for the feedback
Your antennas are awesome.
I’ve been following your work and find these principles very interesting. My retirement looks like I’m gonna be having some fun👍🏿👍🏿👍🏿
Glad you find them interesting I too am a semi-retired teacher and looking at expanding my interest into radio astronomy so should keep me busy for a decade or so.
Great videos keep them coming! Have you ever tested or built a wide band receiver antenna such as you would use for a scanner?
Do you have any videos on how to create a bi-quad that are for 4g LTE networks?
Will this work for an element on those old offset sat tv dishes?
works good.
Wonder how far that can work when its fitted to the parabolic dish :D
My parents live half a mile away on a hill
Would love to beam my wifi connection to them.
Your antennas are awesome, I've made a biquad following your videos, wish you would make a video showing a repeater biquad or double biquad as the cantenna I made wasn't as good as the biquad, cheers Dazzza
darren waters Thanks for the feedback Darren. Now there's an idea!
+Andrew mcneil Currently I have 24dbi grid dish, with 2.4ghz dipole feed. If I put this as feed, should I expect improved signal?
can you make a anntena for my tplink 822n please explain how to sold it?
This is fuking awesome
which is the gain of the antenna
Can I plug this antenna to a router? to remove its omni antenna
Did you measure the VSWR of this dual polarized bi-circled biquad? It seems that the two pairs of elements might react with each other. Why did you choose a bi-circle instead of a biquad for this design?
Hi
Do you know how conect a USB rt3070 to a USB router openwrt to expand my WiFi ?
Regards
Hello !!
When you feed this type of antenna to a parabolic reflector is it better antenna with a reflector or without a reflector ??
Thank you !!
Allow me to reflect on that question
I have gotten caught up with these FPV drones, and I'm confused as to how these guys try to stretch the mileage on the video part of this hobby. Somebody needs to educate these guys to quit messing around with 5.8Ghz frequency's if you want distance. Apparently they don't know that the lower the frequency, the farther it can travel. So why 5.8Ghz range??
I would think you would be better off transmitting video in the, let's say, 900 Mhz range and probably add a few more kilometres. .... But then I constantly keep forgetting that common sense, logic, & rational reasoning left the planet around the start of the new millennium 20 years ago or so....silly me
