Tripod Camera Mount
Dovetail mount quick release plate

Homebrew dovetail polypropylene mounting block 42 mm x 42 mm. File a 45 degree edge on two opposite sides to create the dovetail. You can use a section of cheap kitchen chopping block 🙂

This mount has two dovetail faces on opposite sides. With the polypropylene block locked in place the antenna can be rotated on its axis through 90 degrees, from horizontal to vertical polarisation

Although not shown in the above picture, the boom now has a generous coating of Cabots Cabothane clear timber varnish.
