Build an integrated system of ground rod rings bonded to each other
around the whole property as described in the R56 manual. </jk>
I suppose I might have used his Cat5e to pull in new Cat5e with a
braided shield....not just mylar foil but a serious shield. Ground and
bond it at every point of entry.
I think from your text though you're saying the switch at the tower is
where you have the temperature issue. Why not stick a cabinet heater in
there?
This one is $80 with a thermostat included: https://bit.ly/2GZ5XNo
Some enclosure vendors have thermal calculator spreadsheets where you
can estimate how big of a heater you need, but 100W in a closed space
really ought to take the edge off. If there's no 120VAC in your switch
cabinet then get an appliance cord and a couple of strain relief
glands. There are 12V and 24V heaters, but they tend to be itty bitty
10-20W jobs.

We have a rural tower site where the owner has a few houses on the
property, they ran conduit and cat5e between the houses and the tower
so the houses could get Internet access.
But.... with the size of the property and the tower being a big metal
structure, that caused some voltage / ground imbalances that fried
gear at the houses after storms, I believe even through surge
supressors (hich are made to protect against single high-voltage
direct strikes).
We put in some electrical isolation using copper-fiber-copper
converters / switches at the tower, those worked until the winter:
when it got to -30 outside the FiberStore SFPs were unhappy.
Does anyone have good cold-weather solutions? Or were we just unlucky
with those SFPs and should try something else in the cold?
