One of the big problems with off-brand connectors and adapters is their power
handling capabilities. This is especially noted in the right-angle adapter. We
see a lot of arcing when higher power is applied.
Higher power in this case is anything above just a few hundred watts. Whenever
I see an amplifier log report with a lot of high reflected power or PA
Dissipation faults, I immediately start looking at the
connectors and feed line for problems. These are usually found in one of
several places - right angle adapters, and baluns that were meant for low
power, but have been over-stressed with high
power.
My advice? If the right-angle adapters aren’t Amphenol, throw them out.
