I live in a fairly sheltered valley but there are several hill-top VHF repeaters that I can receive very well. However the one repeater in particular I want to transmit to, I can't reach well. I know my signal is reaching it, because it will auto-respond its call sign when I transmit, but I get reports that my signal is unintelligible.
I've using a BaoFeng F9V2+ with a Nagoya NA-771 antenna and I've also tried a Slim Jim but have not been successful at getting an intelligible signal through.
My question is, would using a copper-pipe J-Pole be any more likely to be successful than the Slim Jim or are they pretty much equivalent?
