When i first got into this FPV thing a year ago i bought and ImmersionRC circular polarized antenna set that seemed to work quite well with a 5.8GHz 600mW immersionRC transmitter...but i lost the transmitter antenna and had to find a replacement.
Being poor at the moment i looked for a cheaper option and found this: http://witespyquad.gostorego.com/5-8ghz-circular-polarized-antenna-rp-sma-with-sma-option.html which are the WORST antennas one could ever use.
With the immersionRC 600mW 5.8GHzi got really good reception but these antennas go for about 100 feet before pretty bad interference...go 50 feet more and it is an outright snowstorm...I cant imagine using these things out in the wild.
Anyway, i am trying NOT to patronize or bash any thing here, just pointing out my experience with these 5.8GHz antennas which has grounded my FPV until i get some good ones.
Anyone got any suggestions or thoughts?
