We just installed a Icom 710 SSB radio, AT-130 tuner and a substantial grounding system (see older posts for more details). The final step of the project is to connect the Tuner to a isolated rigging wire. We selected the upper shroud on the starboard side as it's long and conveniently located to the tuner. The rigging on Pacifia is 9/32" on the back stays, lowers and baby stay and 5/16" on the upper shrouds (Not sure about the fore stay). We purchased a Sta-Lok swageless rigging insulator for the job and installed it about 4' below the upper tang on the starboard upper shroud. The shroud is attached with a swaged "T" and after removing the rubber plug the fitting can be turned ninety degrees for removal. It's easy! I hoisted Kathy aloft and she had no problem removing the wire so we could install the insulator at deck level.
