    what type of interference and how do i destroy it?

    the transmitter antenna is only 5 inches above the "deck" of the boat .

    im inside 150 yds line of sight , its a 1 watt transmitter (910) ? , i tried the the rv 800/910 tx and its no better ?

    it looks like when i rub my eyes too hard .

    all the electronics are "on top " of each other , theres no place else to put them . unless this is another transmission @ around 910 is in the area ( i tried to go through all the channels on the reciever to see what it was , all were about the same " static / lines" )

    the osd goes on it this weekend. maybe the rear view . then 6-s

    This is multipath interference. Best way to get over this is using a good diversity receiver, I also had read that using circular polarization on both Tx and Rx antennas you could improve it.

    k
    so i built a clover leaf ( easier than the bi quad ) .

    using 2 patch antennas , on diversity , i get allmost the same issue .

    this time i noticed i actually picked up another transmission ( a security camera ) it looks like ( from the picture quality ) that its very close to my frequency .--

    does this mean im beating a dead horse ?

    just move over to 1.2 ? -theres no way im going to eleminate this guys security cam transmission .

    when im at the lake , im right on top of the reciever , total line of sight , @ 50 yds i get good clear picture , outside of 50 yds it starts reflecting .

    this makes me wonder about my flying ( 4 miles away from the lake with the security cam issue ) somedays it looks like im picking up "some" signal , others not at all - ( wonder how much of my signal from my airplane this "transmision" is crushing ?) ?

    MAYBE , find this guy , and let him know hes interfering with my signal ? , i bet he has a bad antenna . ???

    the clover leaf is on the tx side

    Why not choose a different frequency? One channel up or down should be enough.
