An overview of my SB-221 amplifier repair project — a notebook about what it needed and what I did.
Here’s a homemade, lightweight but full-size triband yagi (with directors and reflectors in V configuration) interlaced on a 32-foot boom. And it works like a dream.
Expand a 40M rotatable dipole into a 2-element yagi with a fixed wire element. Add a relay to the wire and get instant 180-degree rotation, too.

This handy calculator will determine the lengths of coax feedlines and phasing line for Christman phasing — great for verticals spaced 1/4-wave apart. [Note: will not display if you use Internet Explorer].
Anyone can get the gear I use. Visit the store.
