I am using a 24v (BreezeComm PI-CAT5 dual) PoE injector/regulator that
delivers 24V at the antenna which is then regulated to 12V and put in the
power connector on the KN-100. The run is outdoor UTP about 25 Ft. There
is a 14 Ga. solid copper ground.
Is the performace degradation that you have seen on the TX only?
