How can I boost my VHF signal?

One may also ask, How far can a VHF reach?

VHF marine radios are monitored 24 hours a day by the Cost Guard, and are essential in emergency situations. Boaters often mount radios with the legal limit of 25 watts and, depending on the height of the antenna, can reach communication distances as far as 60 miles or more.

Consequently, What affects VHF range? VHF waves, unlike longer waves, are not strongly reflected from the atmosphere; therefore, they do not bend readily around the Earth's curvature and cannot be transmitted beyond the horizon. Their range is further limited by their inability to pass through hills or large structures.

Furthermore, What channels are VHF low?

VHF refers to TV channel frequencies of channels 2 through 13. The VHF signal band is broken down into two frequency bands. VHF low band refers to channels 2 through 6 and VHF high band refers to channels 7 through 13. UHF refers to TV channel frequencies of channels 14 and up.

What VHF channel should I use for a radio check?

Tune to channel 16, the channel monitored by the U.S. Coast Guard. Perform a radio check to ensure your unit is functioning properly—do not use channel 16 this.

What is VHF range?

VHF includes radio waves from 30 MHz to 300 MHz. VHF waves must not exceed the local radio horizon of 100 miles. Slightly higher VHF range of 54-72 MHz operates television channels 2-4, as well as wireless systems defined as “assistive listening.” VHF frequencies 76-88 MHz operate channels 5 and 6.


What factor affects the effectiveness of VHF communication?

A longer wavelength, which corresponds to a lower frequency, as a general rule lets a radio signal travel a greater distance. Lower frequencies or longer wavelengths also have greater penetrating power.
