Best VHF frequency for long range

Bottom line is that unless you’re in a place where the remote receivers are 25 miles apart, a 25 watt radio would probably do the job , so 50 watts is not going to be a handicap. The 100 watters could make a difference on simplex, but only in the fringe areas and then under specific circumstances.

A typical VHF station operates at about 100,000 watts and has a coverage radius range of about 60 miles .13 Ağu 2020

To calculate VHF range, you may want to use this formula: VHF Range = 1.33 × (√H-aircraft + √H-gs) . Where: VHF Range in nautical miles, H-aircraft is the altitude of the aircraft in feet and H-gs is the height of the ground station antenna in feet.

They assume a 5 watt handheld, 50 watt mobile, 5/8 wave mobile antenna with 6 dB gain and 5/8 wave, 6dB gain omnidirectional base antenna at 50′. Urban Environment – Around 1/2 – 1 mile from handheld to handheld, up to 2 miles mobile to handheld, and up to 5 miles or more, base to mobile, with base antenna at 50′.
