Installing VHF and am having trouble finding a thru-deck coax connector WITH A CAP to keep weather out of the connector when the mast is stepped.Shakespear makes a female thru-deck connector but it does not have a cap.I've read all the stuff in the archives that seems to apply to this subject but no specific mention of a supplier. Seems to me I've see pics of this type of connector for mast light wiring but not for coax.Any help will be appreciated.
