VHF is effectively line-of-sight, and no antenna size can change that (although it does improve efficiency for both sending and receiving), so for two handheld radios, you are limited to about 10 km. The only thing that really helps extend the range is elevating the antenna, and repeaters allow you to do that even between two mobile stations. | ||

You can extend the reach using repeaters. This free app is handy for that https://hearham.com/repeaters | ||
