Yeah - Nova 230's on these builds.
We will have an EdgePoint at the top to power ePMP and backhauls. My
initial thought was to use a 5Ch PDU from PF, but I didn't want to have to
put a SiteMonitor Base II+5 Ch PDU in the breakout box. But really - I
think it's the best solution. It also gives
For a simple setup like Steve's dual ODU, I'd probably cheat and do
something like a 4 or 5A fuse at the bottom, assuming about 80W per
radio. Plus they're on the same antenna, height, power supply, bonded
together, etc. For the single run scenario anyway. If it was dedicated
runs, then yeah,
My feeling on topside breakout is that it is easier to replace a fuse then
everything but it sucks to climb to replace a fuse if that is really the
only issue. If I am breaking out up top, I use a fused dc buss with fuses
a bit larger then they should be up top and then fuse for total load at the
this is a good point, didnt think about that

I typically individually fuse each component on the rail.. just trying to
figure out what the best scenario for a split-top/bottom install would be.
I'll definitely put a fuse between the rail and DC cable (that runs to the
top) in my bottom-box. Would you also fuse each breakout at the top?
Don't you have fuses on your 48V rail?

In this scenario - would you fuse each DC run from the small top-enclosure
(where your power/fiber breaks out) to the radio(s)?
I'm looking at doing something similar to power some Baicells eNBs.
TSP/BCM at the bottom, 14AWG DC/fiber up the tower to a small enclosure
where the power/fiber will
We have always gotten our hybrid cable from BestTronics. Great to work
with - definitely recommend them.

It used to be that the index matching gel could dry out. I don't know if
that's still true or not.

For cable lengths we were getting 100' and 200' and we have spares of
each. We end up with lots of slack, but I don't see that as a bad
thing.

Well, you
Well, you need to convey 105/48=2.187 amps.
24 gauge is 2.5 ohms per 100 feet. If you used 4 wires for one polarity and 4
wires for the other polarity, you would have .625 ohms per polarity or 1.25
ohms per loop/100 ft.
So 1.25 * 1.2 = 1.5 ohms for the 120 foot loop.
1.5 * 2.187 = 3.28
