One set of guys would be fine. Put it at 47’ – it won’t go anywhere assuming 
you have a decent base. Don’t underrate the guys – go with 1/4” or even 5/16”. 
With this I don’t see any reason why you’d need to worry about taking the 
antenna down. Just leave it up there.

[I have a Razor on a ‘test’ tower that is 36’ high ... works wonderfully. Note 
however it does not come with the ‘enough cable for a 50’ tower ... it only 
came with 82’ of cable and you’d need closer to 95’+ if the winch is to be low 
on the tower.]

Hi All  Lucky me! I am moving into a new QTH shortly and finally have 10 acres 
to play with for antennas! I also recently aquired 24 sections of used Rohn 
55g(ex comms tower) (on top of the HD 18m tiltover I purchased from the UK to 
replace the 15m tower I lost a few years ago post earthquakes in a Nor'west 
storm that killed my 4 x 12 ele 144MHz EME array.  I am keen to add some new 
antennas for HF (Steppir DB36) but will prob maximise my height at 60ft due to 
high winds in this area. We can exceed 100 mph a few times a year here as I am 
in the lee of the southern alps here in Christchurch. I am ok with the tiltover 
mast but never built/installed a guyed tower .. So keen to get some 
advice/input from someone knowledgeable about Rohn towers. The Rohn catalog 
seems only to show guyed examples from 100ft .... The 45g shows 40-50ft and I 
have been looking on those but extrapolating out to 55g  The DB36 is 17.5 sq ft 
of antenna ... I was keen to have the ability to lower the DB36 in storms to 
ground level so was planning to use an RT Innovation Razor hazer system. I 
think 60ft with top guys on a Rohn 55g is ok ??? Having 2 sets of guys might be 
difficult to lower the hazer quickly if I see a storm coming. So I don't expect 
the DB36 to be up in 100mph winds .. The steppir would fold I think anyway Any 
advise on this type of setup would be appreciated  I think the top guys 
(phillystran - and lower 20-30ft or so in EHS in case of bush fires ) would be 
ok  I'd do two sets but I think the hazer lowering would be complicated ? 
Cheers  Simon ZL4PLM
