[Elecraft] Tower Identification

Yup! Its a Rohn (originally made by Spalding). They made a HDBX (heavy duty)
and the non heavy duty BX tower.

They are 8 foot sections. Each of the sections will fit inside of the one
below it. It was not to expensive to ship it that way.

They are pretty good towers. Watch the wind loading and the they are not too
good for LONG boom antennas.

The are just fine for a  3-4 element tribander. They will even work with a
TH6 but no larger.

73 and good luck!
