Dish arm extension

Tony’s 1.2m dish has a figure-8 style extrusion for the feed arm, so clamps need to have two holes and a centre relief. For the new dual-band horn mount, we needed a bit more length, so I made up some extension plugs from aluminium

The plugs, turned from ally rod
The plugs pressed into place and fixed cap bolts on the underside
Clamp and mounting place with 10GHz WR90-fed WA6KBL and Super-VE4MA 5.7GHz feedhorns that I made for him
