    Well I am considering mounting the new dish they offer with the MPEG-4 on my bathroom fan pipe.

    My only question is, will it be strong enough to support the big dish. It looks like it is pretty heavy. Anyone care to take a stab at it?

    With my condo association I cannot mount on the roof, but I need to clear the trees! So we negotiated the fan pipe! The pipe is pretty high, but I am not sure if it will blow off with the extra weight!

    I think even new customers get a free AT-9 install if they subscribe to the HD package... Hmmm maybe you should call DirecTV and see what they can do for you.:grin:

    If the installer agrees to do that, tell them to pack up and go. That won't be near strong enough to support the dish under wind loading.

    Vent pipes like that aren't anchored securely and are held by a flexible flashing boot where they pass through the roof.

    Just from the information provided in your post, it is clear that your idea is way beyond your knowledge and means on what is needed to mount an AT9 dish.

    First, it is NOT a FAN PIPE that you are refering ti. It is more likely a plumbing vent pipe.

    Depending on how old your house is, the vent pipe might be cast iron or steel(very strong), copper (not as strong), or ABS or PVC plastic (weak).

    If it is steel, it must be 1-1/2 inch nominal pipe, which is close to the actial 2 inches actual diameter needed for the AT9 dish. Even so, it is very likely not plumb and not very well strapped to the house framing.

    Most bathroom vents are at least three inches to accomodate the toilet.

    Such a mounting can be done, but only by one highly experienced in construction. The original pipe going through the roof needs to be cut off and removed through the flashing and replaced with a long 2 inch actual diameter pipe, carefully plumbed and braced under the. Then it must be connected to the original vent and correctly sealed with the proper connectors.

    Thanks for the info! My condo is brand new, so maybe the vent is strong! I saw this installation, and though maybe I could do this myself! See how it is attached to the vent?

    First, that is the new slimline dish - which I didn't think was out yet, must be very recent?

    Second, it is a risky install, you will have trouble getting an installer to do it, and you cant use the support poles without roof penetration.

    I think you are taking a big leap of faith on this one, it is not easy to install and I don't think it would be a reliable install. THink of what the condo would say if the wind hitting the dish caused the vent pole to break/damage the roof. Then you have amuch bigger problem.

    That appears to be the new slim line dish, which I believe, is a lighter smaller version of the AT9. It might work, but almost all vent pipes, today, if your complex is new, will be made of weak cellular core or foam pvc pipe.

    I'm in the same boat here, the pipe on my roof is steel and pretty thick. I'm also getting the slimline dish. Does anyone know if theres any hardware out there that can be ordered for this task?

    It's not just about thickness. The pipe must be plumb and very securily mounted under the roof .... any motion will totally mess up your reception. Also, the pipe must be 2" outer-diameter.

    Understood..I think im going to just have the guys put it into the roof and hope no one busts my chops about it. I just need some kind of bracket I guess to make it appear its on the pipe. I know that sounds sketchy but Im really fed up with the way they go about these dishes around here. The ONLY alternative is TWC and to me that sounds like a monopoly.

    For all intents and purposes however lets assume the pipe meets all the requirements for this kind of task, what would one have to buy to actually mount the dish?

    Can your dish be put on a pole in the ground?

    They would freak about something like that as well....however even if I could, I dont think I would be able to get a clear look at the Southern Sky since theres alot of trees and whatnot, and more buildings attached in the complex.

    Curious - what is the average cost of a pole mount if done by the D* installers? My current 3 LNB is mounted to the roof and after reading the posts I am a little concerned about putting the slimline up in it's place. I do have a location near the edge of the house that would allow a pole mount, the only thing that might obstruct the souther view is some overhead electricla wires, not sure how that would affect it.

    I suspect that the Management knows a lot more that the posters here suggest.

    The guy is in New York City. Anyone who knows anything about plumbing codes in New York City knows that they have the strictest plumbing codes. Everything more than one story in height requires cast iron or steel vent pipes. No pvc or abs plastic vent pipes are allowed. So, the pipe will be sufficiently strong to hold your intended 5 lnb AU9 slimline dish.

    Forget what the other poster said about the pipe being "perfectly plumb." The mounting pole will allow all adjustment needed, even if the vent pipe is not plumb. You need to know the diameter of the vent pipe, so that you can get the necessary two "U" bolts before the installer comes. "U" bolts are sold according to "nominal" pipe size. So the size will match the pipe diameter. The flat part of the mounting foot will need to be bolted to the vent pipe with the "U" bolts. The bolts holding the mounting foot to the pole has slots to adjust plumb, as well as being able to swing to vertical for plumb.

    It appears that you have less to worry about than you or any of the other posters have mentioned.

    I agree with what Mike500 is saying.

    To clarify the "plumb" issue, the dish itself will not be installed onto the vent pipe.
    The mast that comes with the dish is clamped onto the vent pipe.
    Then the mast itself will produce a plumb mounting for the dish itself.

    You're not mounting the dish directly onto the vent pipe but, instead, you are clamping a full dish+pole onto the side of a vent pipe using U-bolts.
