lly work better. I've doubled people's speeds by moving the antennas
down by as little as 2 feet.

Multipath and/or scintillation. It looks like the sun is shining and

Multipath and/or scintillation. It looks like the sun is shining and
65 degrees in Salem. Sun beating on that metal surface can cause
heat waves to rise in front of the antenna causing
scintillation. Sometimes this stuff is black magic and moving a CPE
a couple feet one way or another can ma

Bump it up about 10 degrees and see if that helps your multipath issue.
Does the signal strength stay at -57 or does it fluctuate? On MT gear
it's
very easy to identify it as you'll see -55 for the most part, then -70
for a
quick mo
make that ARE there any

Is there any large metal surfaces immediately in front of the radio
(antenna)? I've seen the metal rim of a brick fireplace stack cause

very easy to identify it as you'll see -55 for the most part, then -70 for a
quick moment. I'm assuming you're using Canopy here - watch the alignmen
I am curious if anyone thinks this is multipath and has a suggestion on
how to fix.
This just happens to be my dads house, radio mounted to a j-mount on eve
of house, clear LOS to tower <1 mile away, -56 signal. This eve is over
the porch roof to the east and signal shoots over the south plane
Jim:
The term "multipath" is commonly used to describe the condition wherein a
sent signal "arrives" at an antenna through more than one path (by something
in addition to or other than a non-obstructed, line-of-sight link).
Microwave signals are subject to a number of degradation modes includin
