How far will a 100 watt FM transmitter reach?
If an ERP of 100 Watt is used, it is very likely that 20 kilometers of range will be reached because a 100 Watt ERP is able to propagate a strong signal as far as 20 kilometers. If an ERP of 1000 Watt is used, it is very probable that the signal will reach 20 kilometers, and it will also penetrate eventual obstacles.

Is GMRS better than CB?
While VHF radio waves – including CB – typically travel farther in rural settings, GMRS’s power advantage overcomes UHF’s slight range disadvantages to give longer range in most scenarios. GMRS may work better in wooded areas, since UHF radio waves can easily travel through small spaces.
What is the best frequency for two way radios?
UHF radios (Ultra High Frequency) operate on frequencies ranging from 400-512 Megahertz (MHz). UHF radios work best for most two-way radio users because the waves are shorter and can get around or penetrate areas of interference, like those found in buildings, thickly wooded or hilly areas, and urban outdoor settings.
