Hello...got a run of cat5 about 450' that is
working but doesn't seem to be sufficiently powering the amplifier built into
the antenna. The device is a Terabeam EtherAnt-Turbo/LR (same as
Proxim's Terastar EtherAnt/LR). It works but SNR should be better.
If I power the thing locally (25' of cat5) it works as it should, so I think it
may be insufficient power.
It's got a 48v 0.4a power supply. I know that
it's far over spec for PoE...but specs were made up from engineers who have to
play it safe for what they recommend. So...any field answers to my
dilemma? Is more information needed?
Perhaps a side question: What drops over
distance...volts or amps? Please consider the non-electrically-experienced
crowd.
Thanks much.
