[TowerTalk] Rohn 45 Bracketed Tower

[Mike Fatchett]

I don't have the manual at arms length but I believe that you can go 2
sections above the house bracket with a minimal antenna.  You need to make
sure you are bolted into something fairly substantial too.

I would definitely look at guying it.  Or sell it and find a self supporting
tower such as Trylon, AN Wireless, crank up etc.

I would not go much over 40 feet as the TH 11 is a big antenna.  The 46 feet
of tower is the total you can go if my 1982 Rohn book is correct without an
antenna.  You need to properly guy the tower per Rohn charts if you want to
put up the entire 75 feet.  You also need to find your location on the wind
map and include that in your guying equation.

> I just purchased a 75 foot Rohn 45 and TH 11 that is currently guyed. I
would like input on how high I can go with the tower with a bracket at 23
feet. The charts for Rohn are a bit confusing to me, but I believe that I
would read it that I could have 46 feet of tower above the 23 foot bracket
for a total of 69 feet. Assuming an 80 MPH installation I should be able to
assume 24.7 Sq Ft of antenna area.   Am I reading the chart correctly?
