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
