The VHF maritime mobile band consists of channels operating in the frequency range 156.000 MHz to 162.050 MHz , apart from those portions within this frequency range that are allocated to the land mobile service.
Read moreWhat blocks UHF waves?
UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception.
Read moreWhat’s better UHF or VHF?
VHF has smaller frequencies which means interference with other radios is common. UHF, on the other hand, is an all-around better signal for long distance communication. UHF is better when using radios for indoor use like buildings or around cities .
Read moreWhat is the range of a 5w CB radio?
The UH850s UHF CB handheld radio is the ultimate compact UHF communications with 5 Watt power and deliver up to 17km# of range . This makes it the perfect unit for professionals who need a rugged and heavy duty radio suitable for various conditions.
Read moreHow far can 5w transmit?
The 5 watt radio can reach up to 12 miles or more . Some handheld radios have 6 watts which can reach up to 20 miles in the right conditions.
Read moreWhat frequency can penetrate walls?
Radio frequency is easier to generate and because of its large wavelength it can penetrate through walls and alike structures. Radio waves can have wavelength from 1 mm – 100,000 km and have frequency ranging from 3 Hz (Extremely Low Frequency) to 300 GHz (Extremely High Frequency).
Read moreDoes RF go through brick?
Brick walls have to be unrealistically thick to be useful . Other materials, such as windows and drywall, are essentially fully transparent to radio waves. Reinforcing a concrete wall with steel rebar did not really improve the shielding, at least at the standard grid sizes.
