Marine mast thread adapter: 1" 14TPI female to Mobility antenna thread
The Peplink ACW-651 is the standard marine mast adapter, converting the Mobility 42G or Antenna MAX threaded mount to the 1" 14TPI female thread used on most marine VHF, GPS, and mast-top antenna mounts. The right adapter when mounting a Peplink antenna onto an existing marine mast or stainless mount that uses 1" 14TPI threading. SKU ACW-651.
What it's for
- Marine mast mounting on vessel masts using 1" 14TPI thread (the international marine standard).
- Replacement antenna swap on an existing marine mount where the previous VHF/GPS antenna used 1" 14TPI threading.
- Mast extender adapter compatible with Shakespeare, Glomex, Scout, and similar marine mounts.

Marine thread alternatives
Some marine mast systems use the larger 1 1/4" 11TPI thread instead of 1" 14TPI. The Peplink ACW-653A (£89) provides that conversion. Confirm your existing mast or mount thread spec before ordering.
