Default Unconventional installation.

Greetings. I am relatively new to DirecTV and have had a situation (and opportunity!) placed in my lap and I'm hoping that someone here may shed some light before I put in a lot of time, money, and effort.

Background information, you can skip this if you want.
I am a student at a university. While here, I am the head projectionist and equipment supervisor for the theater on campus (we run a Barco DP2000 digital projector fed by a DSS100/DSP100, with a Gefen scaler which allows us alternate content including DirecTV, as we have a commercial contract and a dish mounted on the roof). In addition to that, I am a student technician with our telecommunications department. One of the things I get to help work on and maintain is our cable tv headend (we have 64 DirecTV receivers feeding into Blonder Tongue encoders (HDE-2H-QAM), along with several SCOLA feeds, NASA, MTVU, etc). The four LNB feeds hit an amplifier before hitting 8-way splitters to hit 8 Zinwell MS6x8WB-Z multiplexers

The problem.
The location of the theater on campus is that of a lecture hall. This particular building is in a bit of a valley, so our dish is pointing at a hilltop through trees. When a good wind comes, we start getting all kinds of problems. The dish feeding the head end, however, is at the top of that hill and experiences none of those problems.

The proposal.
I want to either relocate our dish to the top of that building, or abandon our dish all together and split the signal pre-amplification to feed a separate multiplexer, to then feed an HFC to utilize the existing fiber optic cable throughout our campus to get then utilize the receiver end of an HFC to get back onto coaxial line to feed receivers. Additionally, I wouldn't mind also using a combiner to inject the campus cable into this same line.

The questions.
...has anyone tried having a dish mounted remotely and utilizing an HFC to get signal to their building? Does anyone see any reason why this shouldn't work, since they make l-band HFCs and ones that will do 2MHz to 3000Mhz (though, typically more around 2200MHz)? For anyone that has sent the l-band along with cable TV...does it pass through a tap alright or would we have to reduce the 1/2 hardline to RG6 and hit a splitter to get the satellite signal off of the cable TV?

The alternatives.
One might ask why we want this when there's such an extensive cable setup already. Well, we show events for student orgs and those events may be on channels not normally offered (not mentioned, but I intend to also get a 95W international dish). It's very expensive to add additional channels (around the tune of $8,000) to what is existing.

So...did I miss any important information? Any questions?

Is this the most complicated setup you've heard of? What other complex setups have you seen or heard of?

You didnít miss any information, you just described too much of it. Considering the nature of this forum I doubt if many will know what youíre talking about.

Your Issue is line of sight - relocate the dish to top of the building- fiber to increase the (distance?) to the roof top (you left that out) -it's just a matter of finding a contractor or company that will do it.

Yes, line of sight is...part of the issue. The other part is the dish is on top of the building, but the building is in a valley so the dish has to point at the hilltop. And yet another is...there's no really good, secure way to mount the dish without it being mounted to the side of the building....which causes us to lose satellite all together.

Campus cable uses DirecTV to feed it, with a dish on top of another building, which is on top of the hill we point at. I want to use fiber to get that feed down to the other building.

This post, along with some others, seems to confirm a few things. 1) ...this doesn't usually happen...at all. 2) fiber should work so long as the HFC does the right frequencies.
