Roof Space on PT40
Looking at your photo, I note that your system appears to be mounted
to one side of the center line. (Your initial question asked about
the center line). If it can be mounted off center, you'll probably
find plenty of room between the 2nd and 3rd AC on most 'birds -- but
you should certainly verify that on any particular 'bird you're
considering. However, keep in mind that the "goat rails" to limit the
width, so you may not be able to fit between an AC and the edge --
but you might be able to install to one side of the vent/skylight in
the area between the first and second AC unit. (Worst case you might
need to install a modified (narrower) vent cover.)

Pete/Don you might think about doing what I did. I made some thick
aluminum mounting blocks so that I could install my satellite antenna
up off the diamond plate enough so that it has a flat mounting
surface. The rooftop of the 1985 PT 40 and I believe later years also
is curved and not flat.

There is no reason that you cannot build a slightly raised platform
between the roof A/C so that the stowed Data Storm antenna would
slightely clear the next roof air. I wouldnt think that would require
raising it much.

I didn't think I said centerline, but I may have implied it. Ideally, for
optimal deployment accuracy, the dish should be as level as possible. That means
centerline on any curved rood is best, but off-center can be used if necessary.
In my current case, and not particularly obvious in the photo, the roof is a
two-piece peaked aluminum, about 2 degree pitch. Makes centerline mounting
impractical without a custom spacer, since the mounting plate can't be bent down
over the peak.

Hey Don, I can see your concern for roof space.
You have more antennas up on the roof than our
local TV station. Are thes all TV?
Just curious, Thanks,

Bigger ones are internet, middle one is HDTV.

The one at the far right (front of coach) is redundant and seldom used, so I
will likely leave it off the next coach. The picture was taken in October of
2005 when the big dish was being installed, and I already knew it had problems,
so I left the other one up for backup. The first big one lasted three days, the
second one three months - they were the first and second ever made so we worked
out a lot of bugs. The current one has been in use since January, and the only
time since then that I've used the front dish is when trees made it more
practical.

All 'birds have radius-curved roofs made of steel with a second layer
of aluminum plating -- older ones have diamond plate and newer ones
have (at least mine has) aluminum with a corrugated extruded shape.
On my coach, the plating only is on the outer thirds of the roof with
the steel in the center exposed. The "wide body" (post-'89) coaches
probably have less curve than the older "all American" body models.

It should not be too difficult to fabricate a spacer blocks to level
your mounting system if you had to place it off center. 'Bird roofs
are quite strong, so the primary issue for a leveling block will
simply be to allow ample drainage for rain water.

Don:

On my 1992 PT40, there is 6'-4" between the rear A/C unit and the
skylite. Then there is another 3'-6" between the skylite and attic
fan. This is on the centerline and is 30" wide in the clear between
the aluminum walking boards. In the 90's, they did not have the
complete aluminum diamond plate cover. These can be modified to give
you the 45" width that you wanted.

Thanks, Ron. You were one of the ones I was thinking of when I said I knew there
were members of the group that had a Datastorm. Is yours mounted in that 6 ft 4
in space, or somewhere else?

That's where mine is mounted.
