Towers - lattice vs. tubular?
 
I'm starting to look for a 55' freestanding tower with house wall
bracket. Am undecided on a lattice type or tubular. Being an old geezer
I am not interested in the standard lattice type which requires
climbing, but a nestable type to be raised and lowered by a crank or
motor. I figure if it can be lowered I could work on it from the roof of
my one story house. Main antenna would be a Cushcraft A4S 4-element or
equivalent - wind area abt 4 sq ft. Not sure I could handle the huge X7
Big Thunder and its 7.9 sq ft., although that would be ideal.

Any first hand experience or recommendations?

About all that I can recommend is nt to do it like a local ham. His tower
is next to his house, but he can not put an antenna on it from the roof and
has to rent a bucket truck or a one man lift to get to the antenna. Seems
he put it at the side of the house and the angle of the roof is too much to
get the antenna boom from the roof to the tower. He only had a 3 element
triband bean and tehn replaced it with the Stepper 3 element and still has
the same problem. He does have a tower that can be lowered, but it does not
do him much good for that reason.

Thanks for the info. I notice that the tubular and lattice towers nest
at 22' & 21'. My roof hgt is abt 16' at the peak on the ends, but only
12' on long side - where I want the tower. Might have to rethink my
placement. Or use a bucket truck, or tilt the tower on the base hinge
when mounting antenna.

Here is how I do it. There is much more to do but it is
operational...No climbing!

Often helpful to just tilt it back with the antenna pointing up so that it
will almost rest on the reflector element. This way you can still reach the
driven element and do tuning and testing and feed point assembly. One of
the tower manufacturers makes an MA40 tubular (40') with crank up and tilt
over come-along arrangement and was very manageable from the ground. I.m
sure 55' is available.

I bought a self-supporting 56' Heights tower with its clamshell
tilt-over-kit unit 8 feet up from the base. I lower the tower with a 3/8"
power drill and never leave the ground for anything.

IMHO, nested towers that leave the boom 22' feet in the air and the antenna
elements 4-to-15 feet from your reach are overrated!

I have found that the older I get the easier I need things to be!
This scheme I am working with allows one to stand on the ground in the
array and do whatever. If I receive adequate warning of a coming ice
storm or hurricane it is concievable to lower it all to a position of
safety as well.

I just looked over the Heights web page and am very impressed. I'm
surprised an aluminum tower could handle the stress from tilt-over
design. Looks like everything I'd need, and very well thought out and
engineered. Might get the HD (coastal) since we had 90 mph winds from H.
Ike, which crashed most antennas or towers in the area, though I am
sheltered up to about 25'. After looking over my own layout think a 48'
tower would be all I need, with antenna on a mast then being about 6'
above tallest oak tree with clear view of horizon - have flat terrain
not far from Houston, but lots of trees. Counted 40 on our 1.25 acre
lot. Had heck of a time stringing 120' wire antenna.
