Shakespeare SeaWatch 3004 — Omnidirectional Marine HDTV Antenna
The Shakespeare SeaWatch 3004 is the most compact antenna in the SeaWatch family — a 4-inch omnidirectional digital HDTV antenna designed for vessels where space is at a premium. Unlike the flat-panel SeaWatch models, the 3004 uses a compact cylindrical form factor with a standard 1"-14 threaded base, making it compatible with any standard antenna ratchet or swivel mount and easy to position anywhere on deck or at the helm. It delivers free over-the-air digital HDTV with full 360° omnidirectional coverage — no aiming, no subscription.

Parts Desk Insights
Best use case: The SeaWatch 3004 is the right choice when installation space is the primary constraint — ideal for smaller powerboats, centre consoles, and any vessel where a flat-panel antenna isn’t practical. The standard 1"-14 threaded base gives you full flexibility in mounting position; it works with any standard ratchet mount including the Shakespeare 4186U Nylon Ratchet Mount. Reception range is best suited to coastal and near-shore use within range of major broadcast markets. If you have the space and want greater range, the SeaWatch 3015 (15", 65 km range) and SeaWatch 3019 (19", 120 km range) offer progressively more range in larger flat-panel formats.
