Use SS or blow ports up during thunderstorms. Those are the only two
options.
Chuck should open a trenchcoat to reveal an assortment of surge
protectors inside.

When he does this, just for shits connect the PSU at the beginning and
bridge all the middle stuff and just see if it works. I will be it
will be just fine.
However I am certain he needs a ton of surge protectors at each end of
all ethernet runs.... just sayin’

thats what i suggested trying first, customer wanted the extender,
irritating
he finally has caved now and will be putting a network rack in the
midpoint and is going to place a managed switch there instead of all
this other unsupportable cobbling. Sometimes we get a win.

Maybe a dumb question, but has it already been tried without the
extender?
400ft is beyond 100m, but not by all that much. It might just
work without any faffing around.

I have a customer fixed on using
https://i.mt.lv/cdn/product_files/GPeRqg_190928.pdf to extend his
epmp f300 radio run to 400+ feet.
if im calculating this right there will be about a 10v drop on
the 24guage cat5, taking the 30v down to 20. If it does manage to
keep the radio powered i see it burning out the poe circuit.
hes fighting me on putting the cambium PSU at the midspan point
and using his own POE to power the extender.
Ive been overruled about telling the customer no, so its
happening, but I want to make sure my math is correct
using
https://www.rapidtables.com/calc/wire/voltage-drop-calculator.html
24guage, 30v, .5 amp, 400 feet shows 10v drop. but im not sure
about the resistivity field
this is a guy who runs constant latency monitoring and initiates
tickets on every blip, so i see this radio move just becoming a
nightmare with this midspan extender in play
