No, How do VHF/UHF radio waves travel? VHF radio waves operate in a band between 30-300 megahertz, while UHF radio signals are propagated within 300 megahertz and 3 gigahertz. These radio waves travel over line of sight, making them ideal for local communications over a few kilometres.
So if I understand correctly, basically the longer the wave length, the better it comes over obstacles?Quote:

It’s my understanding that the wavelength of VHF frequencies is 2 metres and you get better distance than UHF frequencies which are 70cms. FRS/GMRS frequencies are in the UHF band.
How did these walkies work out in the field for you guys ?
The performance of these radios is directly linked to topography. We were never without radio contact. The worst we got was static conversation at 2kms and the best “in bush” was just over 6 kms.Quote:

Awesome. Thanks for reviewQuote:

Our radios came with a 6” stock antenna and we purchased optional 12” whip antennas (Nogoya) for extended range. If you opt for the longer antennas, you have to get the proper ones for the frequencies that you expect to use e.g. VHF or UHF.Quote:
