4ft replacement cable for ICOM IC-ANT-SB. ICOM apparently does not sell these separately, only with their external antenna switch-box. I fabricated a few extra to make available for other folks who have misplaced or broken their original. It uses a high quality gold pin BNC connector from AMP, and Kobicon shielded connector on the other end, with 4 feet of 50 ohm small diameter coax (RG-174) in between. These are not FAA PMA cables, but should be okay as part of your portable radio setup.
