Frequently Asked Questions...

what are some differences between VHF and UHF ham radio?

I am considering purchasing a Dual band ham radio. I have been looking up some research and find that other hams are saying UHF travels shorter physical distance, but through buildings better. does this mean it travels through buildings in an urban environment, or does it transmit and recieve better while you are actually in a building? and does VHF go much farther than UHF signals? any information to add is greatly appreciated to this new ham! thanks a lot!

Answer:

Welcome to the hobby of Amateur Radio (HAM Radio).

The main difference between VHF and UHF are the frequencies they broadcast on. 2 Meter radios (VHF) operate between 144.0 and 148.0 Mhz. 70 Centimeter (UHF) radios operate at 420 Mhz to 450 Mhz.

Granted, Different frequencies do behave differently under varied circumstanses. VHF frequencies makes it through trees and rugged landscapes, but not as well as UHF does. However, if VHF and UHF signals wave were transmitted over an area line-of-sight, the VHF signal would travel almost twice as far. This makes VHF easier to broadcast over a long range. Some of this should have been covered in your testing. You may want to go back to your review book(s) and read up on radio propagation. Understanding it will improve your operating practices.

Most amateur radio operators and repeater operators operate on either (or both) UHF or VHF, so it's a great idea to get a dual band radio, especially if you're just starting out. The local clubs/organizations around here almost all have repeaters on both bands.
