Marine/Ocean
I use lightning arrestors between radio antenna and transceiver, like Andrew APG-BNFNF-350, for marine radio equipment such as VHF, MFHF, UHF, GPS.
I understand that DC block lightning arrester is to block DC frequency interference, but there is likely no DC interference between matched radio antenna and transceiver. Why cant we just use DC PASS lightning arrester for all radio antennas?
On what circumstances DC block lightning arrester have to be used instead of DC pass?
