Yes, 3.65ghz. Purewave/Mercury Networks just responded and you and
George are right. They said that we would see an 8-10 dBm difference
between the uplink and downlink RSSI.

This is at 3.65ghz? 5.6db sounds about right to me for 60'. It is a
big performance hit, but if they do have 1/2 watt per port, you might
be able to raise the tx power enough to still be close to the max
EIRP... of course you'll still be losing 6db on the receive side.

Yes, from the base station to the sectors.

Is it LMR400 between the sectors and the radio gear? 5.6db
sounds like a lot to me.
I'd definitely ask Purewave.

We are going to experiment with some Purewave equipment
that we
have had for a while and one of our possible locations is on a
water tank which means some of the LMR-400 to the sectors
may be
quite long. The loss calculator provided by Purewave shows
that
the loss on 60 feet of coax is 5.6 dB with Cable Run
Efficiency of
31.6 %. Is this acceptable? I haven't worked with coax
much but
that seems like that's a big performance hit considering
the loss
on 6 feet is .7 dB and a cable run efficiency of 89.1 %.
What is
the performance hit the actual signal strength at the on the
actual wireless link?
