The AV-529 (Miller) has been the standard for the last 30 years. I believe
Comant makes a similar device called the 121 as I vaguely recall. They are
both right around $100, which knowing what is inside is a ripoff, but that's
the way it goes.

Any comment on which style COM antenna works best on a tube and fabric
aircraft connected to a junction of tubes?
