Does anyone know the technical description of the standard aerial mounts that vhf and gps aerials screw on to. All I can find is it being referred to as 1" 14 TPI.
I'm trying to find a short plastic extension piece (say 2") but have drawn a blank via the normal marine suppliers. It is very similar to 3/4" BSP, the pitch is near as dammit the same, but the BSP diameter is slightly larger. I was hoping to use some plastic pipe connectors cobbled together to create an extension, but so far my cunning plan has failed me
