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

coaxial transmission line losses are then minimized, and you get a
more accurate reading of the status of your antenna and power
