What is the difference between VHF and UHF?

. Not much. They both work in the same way, but there are subtle differences, such as the ability to penetrate large, steel reinforced buildings.

UHF would be best for applications like that. VHF gives a small amount of coverage range over UHF, this applies to rural areas, not metro areas. UHF, usually, has less interference from other channels.

VHF radios do need larger antennas, which does not always work well on portable radios where size is limited. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
