Marine VHF antennas can be used to receive two-way communications and weather band signals alike. Also, unlike AM or UHF, VHF can receive VHF TV stations and FM radio as well .
Read moreWhat is the most important factor influencing the VHF range?
Your antenna is the single most important factor affecting VHF radio range, and three key parameters determine antenna performance: gain, height and length. The higher the gain (decibel rating), the greater the strength and distance of the radio signal.
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 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.
Read moreDoes VHF antenna length matter?
The length of your antenna determines how good it is at handling certain frequencies ; according to experts, there’s a sweet spot that gives you the best signal. If you use an antenna that’s too long or too short, your signal might cut in and out at times.
