Installation Instructions
Choose a mounting location that is as high as practical, as free as
possible from obstructions, and as far as possible from other antennas
and other strong sources of RF.
1a. You must apply Loctite 242 thread locking compound to the Tip
Section’s ferrule threads and the Base Section’s upper ferrule
threads before assembly to ensure that the Tip Section remains
securely tightened while in service.
1b. Place the lockwasher over the threads of the Tip Section’s ferrule
as shown. Thread the Tip section onto the Base Section’s upper
ferrule, and securely tighten.
2. Use a Shakespeare Style 409-R or Style 410-R Mounting Kit
(sold separately) to mount the antenna to a deck or bulkhead.
Instructions for installing the mounts are included with the
mounting kits.
3. SSB antennas and transceivers require adequate grounding
systems. Follow the radio manufacturer’s instructions for
connecting this antenna to your SSB radio system.
