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 ?
