If its just an EPMP radio and 400' the Tik GPER will work fine. Yes more likely to to go dead in a thunderstorm though.

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.

    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
    <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
