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
