Depending on the frequency seperation it sounds like it is in the ball park.
Maybe even not enough loss. Quick in the head math short cut is that 1 db is
about 25%. That would give you 75 watts out of the duplexer for 100 watts in.
If it is 3 db, that is half power or 50 watts out for 100 in. Any loss between
the two numbers could be correct.
Again depending on the frequency seperation and isolation in DB, you can look
for 1/2 to 1 DB per cavity. That is for each side. So 3 cans per side would
be
from 1.5 db to 3 db loss in the transmitt side and the same for the receive
side.

Subject: [Repeater-Builder] Re: no power out of duplexer SOLVED with more
questions
Thanks Joe.
We did most of those and then found the problem. The T-connector center pin
had
broken off when we apparently hooked up some test equipment and did not notice
it.
I still have one question though.
Is it normal to have 100 watts coming out of radio and only 70 watts coming out
of duplexer?
Wacom 6 can type duplexer.
That seems to be quite a loss. Again I appreciate all the help.
