[John Rosco]

Effective Radiated Power (ERP), Transmit Power with various antenna gain from a 'base' UHF radio.

The higher the antenna gain, the more horizontal directivity the UHF signal is focused and transmitted . . .

 

[John Rosco]

UHF Radio Range:

o The key to UHF radio range reception is the height of the UHF antenna.
The higher the antenna above the ground the longer the range attainable as opposed to RF power being transmitted.



Fresnel zone: At any particular distance from the transmitter and receiver predicts whether obstructions or discontinuities along the path will cause signal interference issues.
