AN /ARC 190 HF ANTENNA COUPLER

The fill port is used to pressurize the coupler. There is an internal pressure switch that will indicate a coupler fault if the pressure is too low. That family of couplers require somewhere around 8 or 9 PSIG. Having internal dry air is good in an unpressurized mounting location to help prevent coupler internal arcing.
