I wish to do more , mobile stuff. Nothing extra special, just the chance to call cq when out fishing or walking and the like. I have a uv5rv, yes i know most dont like beofung radios but i do. I want to improve its antenna to get more range and or reception from it. I was thinking of some form of wire or flexable set up to replace the small rubber duck it has right now. can it be done? is it worth doing? and lastly can you go to far with it, is there boundries i should set, style type or range or costs??
