We’re replacing an antenna fed by LDF5-50 coax up the tower.   At the antenna is a 1 5/8 EIA connector, with a reducer to 7/8 EIA.

 

At the bottom end is a 7/8 EIA flange.    We would like to pressurize the antenna.

 

Current connectors at the top and bottom are L45R that aren’t pressurizable.

 

Are there pressurizable 7/8 inch EIA connectors available for LDF5-50?

 

I was told we can pressurize this coax and antenna by sending the nitrogen up the hollow center conductor.

 

Thanks,
