[TowerTalk] worlds biggest yagi

[Richard (Rick) Karlquist]

The boom on this is only 76 feet.  That would be
19 feet on 20 meters.  This seems way too short
to justify 4 elements.  In fact you can do pretty
well with 3 elements up to a 26 ft boom on 20m.
IMHO, the "full size" moniker applies only to the
elements, not the boom.
