REMOTE COUPLER MOUNTING, RFI and REMOTE SITE INSTALLATIONS
A remote mountable directional coupler vs. a
Power/VSWR meter that is all in one box is ideal since
the remote coupler can be placed very close to the
amplifier or source output. The effects of coaxial
transmission line losses are then minimized, and you get
a more accurate reading of the status of your antenna and
power being delivered. It also keeps possible RFI
troublesome cables away from your transmitter, audio,
data and CW circuits, therefore reducing the chance of
RFI and distortion to your signal.
A Power/VSWR meter that requires you to run coax to it
since it has no remote coupler means you have to mount
the meter very close to your operating position. Since
you’re routing your coaxial cables through it, you are also
bringing in possible RFI that can affect your audio, CW
tone, modulation, and also your PC. The PowerMaster
eliminates this possible source of RFI since the signals
passed to its display head are merely DC voltages from
the remote coupler.
The remote mounting capability is perfect for multiple
transmitter sites, remote power sensing for tuners, PA
stages, broadcast towers, etc. The ability to have the
meter report alarms via the relay closures or the software
makes it a very flexible instrument for remote sites as
well.
Remotely controlled radio applications over the internet
should find this meter readily adaptable with the PRO
application software.

DIRECTIONAL COUPLER CONNECTORS
You may order the unit with SO-239 (standard) connectors, Type-N, or 7/16 DIN.
The connectors are field replaceable if you should need to do so.
