[TowerTalk] HDBX-48 figures for 90 mph zone

[David Jordan]

There is a 40 yr old HDBX-48 at  wa3gin in as new condition... reason being 
the rotor is bolted to the concrete base and steel pipe runs up the middle 
of the tower through the trust bearing and up five feet in the air where the 
tri-bander is mounted.  No twist on the tower this way ;-)

73,
Dave
