Hi, JC --
Yep, lots of happy Trylon users out there.
> I would probably have to “stick build” it as I doubt that I can get a
crane into my yard (even in front… street is 100+ yards away) and it doesn’t
look like something you can erect with a gin pole. What do you think of that?
Erecting it with a ginpole is pretty simple. The last one I did was a
56-footer and it only took a couple of hours.
There really isn't a reasonable ginpole available for it - the factory
doesn't even make one. What I did was to lash the Rohn 12-footer to the leg and
double-blocked it to give a 2:1 mechanical advantage (some of the lower
sections are HEAVY!). The only trick is to make sure the ginpole doesn't slide down;
I used a carabiner held by a sling to a diagonal to keep it from slipping
down.
> Will it save some bucks, ordering it broken down?
The factory prices are the same as assembled so no money savings there.
It's not a common configuration and the factory gets all excited about the
sections not assembled to their spec so I don't know if it's even available
knocked down.
> Shipping should be cheaper too.
True but with the freight for an assembled one available for $444 that's
almost as cheap as it gets for shipping.
BTW the tower is in stock and you could have it in a week. I've also
installed a bunch of these so would be happy to pass along all the
tricks-of-the-trade.
> Will an OR2800 fit in the top section?
Yep, it just needs to be field drilled. If you're going to be using a
tall mast, then you'll want to go with the lower rotator plate. The plates go at
the top of each section and then 3 feet below so a big mast/rotator should be
mounted at the top of the next section down. That'll give you 7 feet of mast
in the tower (deducting 1 foot for the rotator) and the remainder above. You'll
have a total of three plates: the top TB plate, an intermediate one 3 feet
down (this'll capture the mast for any future rotator swaps since the mast will
be pretty top-heavy at this point), and then the rotator plate. They run $49
each.
