The Gain of an Endfire Array
- This article looks at the maximum theoretically possible directive gain that could be obtained with an endfire array of given length or number of elements, and compares this with practical results in the literature.
Antenna Gain to ERP
- A radio's transmitting power can be concentrated along the horizon by use of a GAIN antenna. Although you may still be transmitting with four watts of power, your effective radiated powerwill be greatly increased. This table shows the effects of antenna gain on a transmitter with 4 watts of transmit power.
