We climbed the tower on Sunday and checked things with the wattmeter
between the Feedline and the antenna.
At the bottom, we were making 75 Watts at the duplexer output. At the

we plan to replace the Telewave F10 with another DB420 we have and if
that works
Cort,
It sounds like a "mechanical" problem somewhere, as others have mentioned.
If you can get your hands on a TDR or similar device to sweep the new
antenna and feedline on top (using calibrated 50 ohm load on the
feedline, and then adding the antenna on for the next test), you'll

Wow! There is a lot of wisdom on this site, and I certainly appreciate

Question: If I use the folded dipole array, how far away from the mast

This is why on the UHF arrays the dipoles are paired.

You let the bp/br duplexer take care of the in band problems and then use a

the out of band problems if needed.

Adding a preamp to some repeater systems does not always make it "hear"
better; sometimes the receiver becomes more sensitive to overload,
intermod, desense, and has a higher noise level. You can mitigate some
of these problems by placing a bandpass cavity immediately in front of
the preamp.
