If you want to improve reception on these radios sometimes they will bring an extra connection for an antenna. You can create a very efficient long line antenna with copper or stainless wire and some weight at the end (like a nut).... If you are close to a tree you can loop the wire around a branch and it will increase the reception... The wire is very light to carry and it does not occupy lots space .... I done it many times and usually it improves recetion greatly....
