Passive gain vs. active gain
. . . .
Passive Gain
Active Gain
- Accomplished by focusing the RF signal with the use of an antenna.
- Does not require an external power source
- Internal workings of the antenna focus the signal more powerfully in one direction than another.
Active Gain
- Caused by the transceiver, capable of transmitting at different power levels.
- Use of an amplifier connected on the wire between the transceiver and antenna.
- Amplifiers are typically bidirectional. They increase AC voltage inbound and outbound.
