immersion rc diversity with two 5.8 helical antennas "home made variety just thrown together not perfect " works very well.. its switching between antennas in the video although you probly had no idea "i have the tick noise on so i can hear when its switching " .. Much better results from the helicals than with the skewplanar & helical .. Huge thanks to alex /i b crazey & jason tepper ..I could of gone for a longer distance iam sure but the weather was not great & started to rain .. But not bad for a bit of biscuit tin/hotglue/ electrical wire/.cocktail stick ... For what it would of cost me for the antennas alone ive almost purchased the diversity controller give or take a few £ & made my own antenna's from scrap
