Default Antenna Mast Cap

2004 3100SE that I've removed the TV antenna from the radar arch since I don't need it. Does anyone know if there is a cap available to screw on the mast to prevent rainwater form getting in. Not a very major problem, just trying to accumulate parts while boats in storage.

If its a standard 1 threaded mast stub then a pvc cap from the plumbing supply of the local hardware store may have matching threads

Do you plan on installing something else there? If not, remove the mast fill holes with a 2 part epoxy leaving a mall dimple/pression, then fill depression with gelcoat and wet sand and buff.

Thanks Shrew, good suggestion for permanent removal however I wanted to keep the short "mast" there for possible use in the future(?). That's why I was thinking about just capping.
