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

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.
