The Shakespeare 5215-C-X is a masthead VHF antenna package for sailboats: a 3-foot stainless whip plus 60 feet of low-loss RG-8/X cable and a stainless L-bracket, so the long run down the mast loses as little signal as possible.
Who it’s for
- Sailboats mounting VHF at the masthead
- Re-rigging or replacing a failed masthead antenna
- Long cable runs that need low-loss coax
Key features
- 3 ft (36 in) length, 3 dB stated gain
- End-fed half-wave stainless-steel whip
- 60 ft RG-8/X low-loss cable
- PL-259 connectors and SO-239 antenna connector
- Stainless-steel L-bracket for mast mounting
Choosing the right antenna
-
Gain vs. beam: a 3 dB antenna has a wider signal pattern that keeps working when the boat rolls or heels, which suits sailboats and rough water. A 6 dB antenna concentrates the signal toward the horizon for more range on stable powerboats.
-
Height is range: VHF is line-of-sight, so mounting the antenna higher does more for range than extra gain. On a sailboat, a short masthead antenna usually outperforms a long antenna mounted low.
-
Coax matters: RG-58 is fine for short runs; RG-8X loses less signal over longer runs; RG-213 is the choice for long commercial runs. Keep connections dry and sealed.

Before ordering
Confirm masthead mounting space, your total cable run, connector compatibility, and clearance from wind instruments and other antennas.
