Cactus V2s transmitter antenna modification
Quick antenna modification for the Cactus V2s transmitter. Soldered a ~15cm (~6") piece of wire to the board, made a hole on the top part and glued a cover of an RCA plug (that is why there is a hole, didn"t find any other suitable thing) as the cover for the antenna wire.
I did a quick range test in a warehouse with the Cactus V2s set and modified antenna. It worked without problems or misfires from the other side of the warehouse, I'd guess it was about 70 meters away which is probably more than I'll ever need. I think I'll test the range with a straight antenna someday.
