I am on the lookout for a GTO15 cable clamp that secures the GTO15 from the tuner to the backstay (or shroud) in a connector box.
This device was seen on a neighbor's boat and he can't remember where or when he purchased the device. The GTO15 HF cable is secured to the take-apart housing (made of 316/304 SS) which securely clamps onto the shroud. The GTO15 cable is totally sealed and threaded on the bottom of the housing, and is stood-off the backstay by the typical 4 inch standoff.
If anyone has seen or knows the whereabouts of one of the these devices, please post.
Attached is a quick pic that I drew on Google Sketchup of the device:
