Regarding investing in a Rohn Catalog for BX information: I noticed in my last
shipment of catalogs from Rohn, that the BX information has been left out of
their
Commercial catalog since they no longer make the BX series of towers. I suspect
that when they reprint the "consumer" version of this catalog (the one made
mostly
for hams), that the BX information will be deleted from that one too. The
bottom
line is that you had better get your Rohn catalog soon if you want it to have
any
BX information in it . . . This goes for "tilt-over" information too, since
those
have been discontinued also . . .
