To get the best performance, you should use Andrew LDF5-50 Heliax, which is
7/8 diameter, or larger. Anything smaller will suck up significant power
and reduce the amount of incoming signal, leading to poor coverage.

You're welcome! If you cannot find any PA assembly or board numbers, you
can still ID the board by looking for certain capacitor values that vary
among the LL, L, M, and H band splits. It's time-consuming, to be sure, but
it will answer the question of which PA split you have.

To reduce vibrations from the antenna being conducted to the feedline.
As it's not flexible, it will crack and/or break. I've also seen cases
where the antenna connector was vibrated right out of the antenna.
Adding the flexible jumper acts as a 'shock absorber' and absorbs any
vibrations.
We had thousands of 1/2 hardline jumpers connected to antennas at my
last job. It was the standard to use 1/2 LDF4-50A for the jumper.

You didn't have the feedline connected directly to the antenna.
Although I have to question the logic in using 1/2 that isn't Superflex

I just looked at a spare Mastr Exec II PA, and I can suggest a means to
quickly identify which board you have. At each of the four final
transistors (4104P1), there are two 39 ohm resistors
(orange-white-black-gold) and four resistors that are specific to the
bandsplit. The attached

Tel wave includes a RV-213 jumper with their fiberglass antennas. We are not
impressed. We toss them and either connect the feed line straight to the
antenna if it is LDF4-50A or use a LDF4-50A jumper. We have had no problems
with the connectors yet.
