After two years of “all talk, no action,” the radio room has been rebuilt.
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.

Tired of burned-out bulbs in your CDE rotator meter? Replace the bulb with an LED strip — it’s inexpensive and LEDs will last a very long time.

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].
