For example, if your height of eye is 9 feet above the surface of the water, the formula would be: 1.17 times the square root of 9 = Distance to the horizon in nautical miles .
Read moreHow is UHF range calculated?
To calculate the range of an antenna, you multiply the square root of the antenna’s height above water (in feet) by 1.42 . The product will equal the antenna’s communication range in miles.12 Şub 2014

That formula is: Horizon in kilometers = 3.569 times the square root of the antenna height in meters . For example, if the antenna height of a radio is at 6 feet (1.82880 meters tall) the horizon is 2.99 miles away (4.83 kilometers) and another radio with the antenna at 6 feet, that equals approximately a 6-mile range.

Low-band VHF range of 49 MHz includes transmission of wireless microphones, cordless phones, radio controlled toys and more . 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 6.21 Eyl 2015
Read moreWhat is a VHF Hi signal?
Over-the-air TV signals are broadcast on two different bands, very high frequency (VHF) and ultrahigh frequency (UHF). VHF channels transmit at radio frequencies between 54 MHz and 216 MHz, while UHF channels come at much higher frequencies between 470 MHz and 890 MHz.
