Jerry, howdy --
Yes -- the Rohn catalog(s) is the FIRST thing that I recommend that anyone
contemplating any tower installation obtain. They produce 2 catalogs: one
for Consumer Products (BX, 25G through 55G and SSV) and a Commercial Products
version that covers everything except BX. They are available from Rohn
(309-697-4400) or from most Rohn dealers. They are $10 from Rohn with a
voucher toward the purchase of Rohn products so you get your $10 back.
Both of the catalogs have a bountiful supply of specifications relating to
wind loading, guy anchors, bases, hardware, tools, etc. The latest versions
have been updated to TIA-222-E (the industry standard) as well as 110 MPH
wind charts.
EVERY HAM should have one.
