Maarten Beart spent Months designing and simulating a better antenna that out preforms our current standard for video antennas, what he has come up with has changed the industry!
Don't forget that if you get 3 or more sets of antenna kits you can use voucher code "freejig" at check out to get a free assembly jig which you need to build these to the tight specs you need. Don't need that many, then head over here to pick one up: Pagoda Hybrid Jig
Revision B has been specifically tuned to be used with a cover and keep the same performance as a regular pagoda and is ideally suited as a stubby. Please note that the Rev B needs a cover to perform correctly.
We suggest using Rev B as a transmitter antenna with a cover.
From the images below you can clearly see how much better the Pagoda does at producing the desired polarization with out inducing the opposite like our current goto's the Skew and Clover!
This means that you will have cleaner video because you will not receive the reflected wave from your own transmitter, and by using LHCP with RHCP you can more easily fly on adjacent channels with out losing video quality!
Center frequency: 5.8 GHz
Bandwidth: 500 MHz (5.55 .. 6.05 GHz)
Matching: S11 < -20 dB, VSWR < 1.22 (at center frequency)
Axial ratio: < 1.3
Radiation efficiency: 92%
Can you shorten it? Why yes you can!
We do suggest keeping the receiver the spec length of 90mm or longer, however the transmitter could be shortened to 30mm from the bottom PCB to the end of the SMA
