You should just buy it so you can tell me how bad it sucks. I fpv with 8 guys,,,, they all have there own idea of whats best. One cat in particular is running 4c diversity.... it's a mess.... for a back pack guy it's obsurd.
Those rubber duck to rubber duck will do miles with perfect reception. if it's not, your getting the wong rubber duck.........it's all about the exact parts in the craft, how there hooked up and how the rest of the craft is clean = great reception and crappy setup is a mess of video service. Things like exact length wires through out, no wires is better like using sbus/ppm cut to exact lengths.
1.3 sucks, makes sattelite stuff flat not work or take forever to get a signal, not enough difference between 900 and 1.3,,,, 5" vs 7" CP antennas........ You'd be so much better off with immersion 5.8 than this conglomoration of crap you keep trying to piece together. You really gotta watch all them chineese contraptions, there snake oil
I follow the trail of the masters before me with my gear. Guys like RiscyD, Trappy, Sentry, all run lawmate 2.4,,, TBS in particular runs EZUHF so that's how i roll. I bought Dragonlink, guess what, first real junk i had to dump on a classified add. I had 900, 1.2, 1.3, 5.8 video, mostly always on CP antenns and they all sucked. 2.4 on ch5 or ch8 is amazing. can fly next to all the 2.4 radios with no problems. Can do 5 miles in low gain diversity basicaly no less than a mile behind my antennas and with a quad, even with LRS rc control making a mile and back is about there limits.... most flights for me and my friends are a few thousand feet, but down in and behind stuff.
