For radio frequencies, around 20 Meter/14 MHz is a workhorse (DX – Long distance) frequency range, and the 40 Meter/7–7.3 MHz band is also often the best for long distance communications.
Read moreIs VHF the same as FM?
VHF- Very High Frequency Very high frequency is commonly used for FM radio broadcast , two-way land mobile radio systems, long-range data communication, and marine communications, just to name a few. VHF includes radio waves from 30 MHz to 300 MHz.21 Eyl 2015

VHF, in full very high frequency , conventionally defined portion of the electromagnetic spectrum including any radiation with a wavelength between 1 and 10 metres and a frequency between 300 and 30 megahertz. VHF signals are widely employed for television and radio transmissions.

In the United States, the frequencies used for these systems may be grouped into four general bands or ranges: low-band VHF (49-108 MHz ), high-band VHF (169-216 MHz), low-band UHF (450-806 MHz), and high-band UHF (900-952 MHz).

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
Read moreHow is VHF range calculated?
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.
