reat forums on this website.....

I live in a condo with a flat roof. I want to install a new Direct TV Slimline dish. The dish on the roof now is attached to a drain standpipe on the roof.

The installer tells me that the new Slimline dishes are too large to be attached to the standpipe, and I will need to get a non penetrating rack to attach the dish. I called off the install until I can brief the condo board on what I need to put on our roof.

The board looked at the roof rack examples I found on the web, and they really don't have a problem with me doing this. We have about 15 dishes on the roof now, and I'm the first to want to upgrade to the larger HD dish. They figure other condo owners will want to upgrade, so they want to use my install as the baseline, and try to set a standard for the other installations.

My questions to the install experts here are:

1. Is it impossible to mount the larger dish on a standpipe? I have noted some "pipe adapters" on some of the equipment websites that slip over and bolt to the standpipe, and you attach the dish to the adapter. Its the "quick pipe" adapter on the AIsatellite dot com products page.. I apparently am not worthy enough yet to post the link......



Will Direct Tv install a dish on one of these adapters?

2. How useful are the pads under the non penetrating racks?

Thanks for the help, and I apologize if I've posted in the wrong forum here....

Personally, I would NOT do the Slimline on a sandpipe, it weighs alot more than a standard dish.
I have mounted the old single or 3 lnb dishes on the sand pipe, but would not reccomend the Slimline on it.

Please, please, DO NOT mount it to the vent pipe.

I am a commerical (flat) roofing estimator/project manager been doing this for over 10 years.

The non penetrating mount is the ONLY way a consumer dish should be mounted to the roof by a dish installer. These type of mounts are very good for the application. They will not damage the roof membrane.

A pad under the mount will always be a benefit no matter what type of roof membrane is up there. Depending on what type of membrane, determines what kind of pad should be there.

Here's an example of the mount.

Non-Penetrating Roof Mount NPR4A 8 Blocks 3' x 3'

A couple of concrete blocks hold it down.

Do not use the "pipe adaptors". I wouldn't even recommend a single LNB dish be mounted to a vent pipe.

Vent pipes do not have the structural strength to support anything. The wind load on a dish will cause the pipe to move eventually causing the pipe to crack at a joint allowing gases to enter the building. I have seen this happen many times.

Simple and easy is not always the best way to go.
