A Question of Measurement
In the latest (March 1997) issue of QST, I have written a column
entitled: "Talking to the Town." I solicit contributions from this
reflector, however, on how to present the issue of size to a town body.
Rohn 25 is an antenna support structure 12 inches in face width.
Rohn 45 is 18 inches in face width. Yet each is built with a lattice
structure. As a Volunteer Counsel, I think I'd like to make those
measurements seem even smaller, if the right phrasing can be created.
Lattice towers have a lot of open air, so I'm thinking it ought to be
possible to craft sentences such as:
While carrying a 12 inch face, for each square foot of structure, only
____ square inches of that square foot is steel. The rest is clear air.
For each square foot of this structure's face, only ___ % is solid
surface, dramatically reducing visibility.
I would welcome your suggestions, calculations, or measurements, for Rohn
and other towers..

Big antennas, high in the sky, are better than small ones, low.
