5. Amplifier Connections and Indicators
CAUTION:
Only use high quality N-type connectors. Do not use PL259 “CB” type UHF
connectors. Doing so will ruin the N-Female jacks and void your warranty.
Transmit LED:
This LED glows RED when the amp has switched to the transmit mode. This occurs
when the amp detects RF power at the jack labeled “To DC Injector”. (See Section
9 operation for more information)
Receive LED:
This LED glows GREEN in the receive mode when DC power is applied to the
amplifier. It is goes off when; the amp is in the transmitting mode.
DC Injector
Connection:
This N-type female connects to the DC Power Injector via the transmission cable.
The length of this cable will determine the type of cable that should be used. See
the installation diagram and the Appendix for more information.
Antenna
Connection:
This N-type female connects to the antenna with a short length of low-loss coax
cable.
6. DC Power Injector Operation
A DC Power Injector is an in-line device which “injects” the DC power necessary to operate the
amplifier onto a transmission line. This allows the coax cable to carry both RF signals and DC
power to the mast-mounted amplifier. This precludes the need to run a separate power cable to the
remote mounted amplifier.
When grounded to a good earth ground through either the grounding stud or mounting flange, the
DC Injector will provide maximum lightning protection to your radio modem, wireless LAN card or
Access Point.
