Ummm... don't let the new site owner see these.

ALL LMR and PAGING TRANSMITTERS not equipped with a Pass-Notch
duplexer, will have an additional pass cavity installed to prevent
spurious emissions and minimize ambient RF noise to the other
equipment installed at this, and adjacent sites. An isolator
is also required between the transmitter and the cavity.
There are to be no PA decks, isolators or circulators looking
directly into an antenna, even a temporarily unused one.

I forgot to mention my pet peeve. Please label everything. Extra
credit for a block diagram showing where the wires and cables are
suppose to go. Here's mine:

Ummm... Bad example. Do like I say, not like I do.
