I did this repair many years ago after the mounting failed on the X-300 (original single bold stub mast) which allowed the antenna to sway. It gave a few more years of service after the repair and mounting modification and was only taken down to be replaced with a new X-510 which has the same mounting modification.

It started as a simple project to construct a switch box so I could use a single microphone with multiple radios in my home shack. It’s ended (although i’m not sure it will ever end!) with more knobs, buttons, switches and flashing lights that the flight deck of a Dreamliner.
I’m still experimenting and will be posting a walk through soon so stay tuned but for now, here’s a little picture…
I like to take part in the 2M UKAC run by the RSGB when I can so I made a simple, lightweight 5 element yagi that I can put on my 10M mast and use portable.
