Why is the height of a VHF radio antenna important?

Antenna Height

When considering marine VHF radio communications, more important than all other factors is the height of your antenna. The higher you can place your VHF antenna the further you will be able to communicate. … Any angle beyond vertical will lessen the performance of your radio signal.

Is 121.5 still monitored?

Flight Service Stations will con- tinue to monitor 121.5 MHz, and aircraft pilots are technically still required to monitor this frequency at all times if it’s possible with installed equipment. After all, 121.5 MHz still remains the GARD frequency for airborne emergencies.

How far can a VHF radio transmit?

A typical VHF station operates at about 100,000 watts and has a coverage radius range of about 60 miles. A UHF station with a 60-mile coverage radius requires transmitting at 3,000,000 watts.
