    Hi Guys Just a Multi question I have to have quite a long feed to my Half Size G5RV st 30FT high with 80M Inductors with ends hanging down give it 80M very limited on space only about 60Ft pole to pole between my garden and part of a friendly neighbours garden and so lay out is best I can do.

    With the idea of using higher power should I have a Choke / balun at the Antenna ladder feed point to reduce the chance of RFI or RF Feed back?? at the moment the ladder connects straight to the coax feed...

    I am wondering if the Coax feed could be seen as part of the Antenna and bring RFI at higher power level's as I especially want go on 40M and 80M with the antenna will the coax Feed at high power be problem....

    Any ideas besides moving home :),... Are welcome thanks in advance...
    Or should I even look at another type of Antenna ?

    Cant go up above 40FT local UK Planning rules count that out, and Gardens real small....
