ProTek Antenna Base Cap
Protect your antenna base — and your boat.
When your antenna is removed for travel or storage, your exposed base is left open to water, corrosion, and dirt. The ProTek Antenna Base Cap is designed to thread onto common standard 1"–14 antenna bases, creating a secure seal that protects sensitive coaxial fittings from the elements.
Made from a semi-flexible, rubber-like material, the cap won’t scratch or damage your boat — even when it’s not in use. A built-in lanyard loop allows the cap to stay attached to the base or rail when removed, so it’s always ready when you need it.

Soft on your boat. Tough on corrosion. That’s ProTek.
