Hi, I'm new here and i don't know all the technical terms of radios and all that. Just have a problem. I use a UV-5R Baofeng radio I need to be able to clearly receive a frequency around the range 454.000 the problem is that after about 3 miles it gets unclear then cuts. I need to receive it about 6-7 miles away. Is there any antenna that i could buy to extend the receiving range? I dont care about transmitting, i dont need it for that also would a larger antenna drain the battery more? (its only to be used for receiving) sorry if my question is a bit daft, but i do not know much about this topic. any help is greatly appreciated.
