I have noticed on my Mighty fine junk diplexer, I get around 10 to 15 DB of
insertion loss on 2 meters receive.
Is this normal for a diplexer?
There is a repeater about 100K away from here that usually comes in around
S3 to S5 during the day...until I took the diplexer out of line, at which
point it was coming in at S6 to S9...I switched the diplexer in and out
about three times to make sure it wasn't just conditions going up and
down...and got the same results.
I also checked to see if it did the same on simplex...and I found the same
general results.
I suspect that instead of having a 0.1 DB insertion loss, this particular
diplexer has a 10DB insertion loss.
