Shakespeare HA156C VHF Antenna

Low Windage Helical Stub - 0.15m Length

The Shakespeare HA156C (V-Tronix series) is a high-performance, ultra-lightweight helical VHF antenna designed specifically for race yachts, RIBs, and sailboats where minimizing windage is critical.

Questions & Answers

Is this a genuine original part?

Yes, this is a genuine Shakespeare V-Tronix antenna, supplied in original retail packaging (blister pack).

How do I know if it is compatible?

We recommend checking the SKU/MPN (HA156C). If you are looking for a compact, masthead antenna for a standard VHF radio (156-162 MHz), this is the industry standard choice.

What connector does the cable have?

The 20-meter RG-58 cable comes with a PL-259 connector, which is the standard plug for most marine VHF transceivers.

Note: For AIS-specific tuning (160-162 MHz), please see the HA156C-AIS model. This HA156C model is optimized for standard Marine VHF communication.
