I decided to replace my old (20 years) mast head amp to try to improve
signal problems.
I have been running a dual UHF/VHF antenna as well as a hi gain UHF
antenna using a combined
masthead amp/diplexer.
To my disappointment I found the signal on the new amp to be worse for
the Canwest transport.
In order to diagnose the problem I changed the diplexer switch from
separate to combined antennas.
This produced a marked signal quality improvement.Next I disconnected the
VHF antenna cable from the diplexer.
This improved things a little more.
It seems the UHF signals from the two antennas were probably interfering
with each other.
