Linear Amplifiers to increase the RF Output and Range of low-power transmitters.

Use these Amplifiers to increase the output of a 5 ~ 10 milliwatt transmitter by up to ~ 1000 milliwatts E.I.R.P. (the maximum permitted output for the Low Interference Potential Devices listed above)

The transmitter output (normally connected to antenna) connects to the input of the Booster and the Booster output connects to the antenna.

Antenna Gain... what does it mean ???
a simplified explanation

Received signal strength from an antenna with 3 dBi gain will be double that from an antenna that has 0 dBi gain, received signal strength from a 6 dBi will be double that from a 3 dBi and so on... An increase in antenna gain of 3 dBi is approximately equal to doubling the transmitter output power, received signal strength or range can be increased by raising antenna gain or transmitter output power. Range can be doubled by either increasing antenna gain by 6 dBi or quadrupling the transmitter output power.

Increasing the gain of the receiver and/or transmitter antenna is an alternative to increasing transmitter output power.
In very simple terms: increasing antenna gain from 0 dBi to 3 dBi is equivalent to raising the Power Output of a 1 Watt Transmitter to ~ 2 Watts, 5 dBi ~ 3.3 Watts, 8 dBi ~ 6.6 Watts, 12 dBi ~ 16 Watts, 15 dBi ~ 32 Watts, 18 dBi ~ 64 Watts, 21 dBi ~ 128 Watts, 24 dBi ~ 256 Watts.
