I chose the PST61 and other than being a pain to install, it is as tough as
anything I have seen. Have a good friend who has been trying to use the
M2/2800 with lots of problems, although in fairness, M2 seems to have been
helpful.
The PST 61 seems to be both foolproof and bulletproof. I am turning a F12
Mag340N, C31XR, and 180B-68'rotatable dipole on a 24'-172# chrome molly mast
with it and it never even blinks. We get a LOT of wind on this hilltop (300'
drop within a mile) in three directions so we have almost constant winds of
some degree but when it storms we get slammed..Not a problem. I do not like
not having anything provided to center the mast within the rotor
clamps...that is a pain.
Bought it from Jay WX0B a couple of years ago and have no regrets. Also,love
the control box, just turn the knob to the desired degree and let it
go..beauty in simplicity. I have had pushbuttons, programmables etc. but
this is the easiest to me personally.73, Tommy WD4K

I'm not familiar with the M2 rotor, but to me, the HDR- 300 isn't even in
the same league as the PST-61. I went through several HDR 300s in as many
weeks. I ordered the PST-61 and it's been going a good two years.
There are probably better rotors out there, but my experience has been some
what limited.

This may not be specifically applicable to the situation under discussion,
but
the concept might be useful. I created a flat-roof "tower" of sorts using a
Radio Shack steel telescoping mast (not the wimpy 10-ft-section TV mast), a
large Radio Shack tripod, and three very heavy concrete deck footings
obtained
from Lowe's. I drilled holes in the footings with a masonry bit, and using
lead
masonry anchors secured the tripod to the bricks with lag screws. Guying the
mast four ways at the rotor with nylon cord (dacron would be better), I was
able
to put up a fair amount of VHF aluminum at fifteen to twenty feet. Could
easily
handle a small tribander instead. The mast scarcely moves in 50-60 MPH
gusts.
And no holes in the roof! The hardest part was getting the concrete footings
up
on the roof. <heez, heez...>

Yikes indeed...
I'm no legal expert, but, theoretically, there are legal mechanisms to
restrict the tyranny of the majority in just such cases (which is probably
why there are always all those "grandfather" clauses.. easier to accomodate
than fight). For instance, the common area group couldn't pass a rule that
prevents you from driving into your driveway, or, that requires you to burn
your house down. Such things are considered to be "not in the public
interest".
The real problem is that it's theoretical.. you still have to pay an
attorney to slug it out in court, and it's unlikely that there is some
agreement that "loser pays fees".

I'm looking to develop an annual, semi-annual, and quarterly maintenance
checklist for antennas and towers. Does anyone have anything like this?
Any ideas on what I need to consider for each of these checklists?
I'm thinking I'll need to have:
1. Items to check, repair (i.e. only if broken), and replace (replace
no matter what).
2. Items to retighten, re-terminate, etc.
3. Antennas to re-aim
4. If unlicensed frequency, spectrum analysis report
5. Antenna/cable sweeps
6. Anything else?
Thanks for any input!

Craig.... You can purchase them from a supplier of utility poleline
hardware. There is probably more than one manufacturer, but the ones I am
familiar with are made by Preformed Line Products (same guys who make the
preforms that terminate guy cables). They are called "Guy Guards/Markers".
In Texas one vendor is Power Supply, Inc. I believe they have offices in
Austin, Beaumont and Houston and were very helpful when I ordered mine.
I have Catalog No. PG-5718 on my guys. They are yellow, 8ft long and in 1998
were $8.50 ea. They come in cartons of 25 but, fortunately, I was able to
buy them individually.

Oops... You also asked why.
The PST-61 is rugged, requires no brake and has no play.
The HDR 300 requires a brake, the brake switching is really odd ball in that
you have to manually turn off the brake and then turn the antenna. The
output shaft turns relatively easy with the brake off. Turning the brake
off in high winds means the antennas are going to weather vane "right now".
Then at the least you have to dismantle the rotor and get it back between
the limit switches.

Fix the bolts and you won't be shearing off the other bolt. Those rotor
plate bolts have to be solid. Mine is keyed and bolted to the shaft with 4
bolts in the plate. Any play in the system puts a tremendous load on not
only the rotor, but the whole tower when it comes up against the stop.
I have on the order of 300# worth of masting plus a TH-5 at 100 feet, 7L C3i
at 115 feet, and 2 11-L 440s and 2 12-L 144s on a 14 foot cross boom at
130 feet. 70 MPH plus winds a couple weeks back caused the mast to slip
about 10 degrees in the mount, but nothing broke. I just have to go back up
and realign things.

It only takes a few degrees of play to shear bolts in winds far less than
the system design.
I had mine shear off some 5/16 ths stainless pins in the mast. Reamed the
holes and put in 3/8ths (tight fit). I think I got those sizes right. I
haven't been up there since late last Summer.
