Can anybody help me ? I need to move my brother in laws dish since they have been cancelled on once again . So it is a at 9 and I did my own but the problem is that his is already 100 feet from the house and to recieve hd it needs to move 50 to 75 feet more so I need to know what length max is or what else can I do . also it needs 8 outputs help please .

It's not recommended to exceed 100ft for H20 & HR20 MPEG4 receivers. Older non MPEG4 can go up to 200ft.

What about some sort of signal booster? or a powered multi switch ?

Signal booster interferes with the frequency range needed for the new Ka band. Multiswitch provided by installer doesn't act as a repeater to improve signal, it just allows more receivers to be connected to one dish, but the retrictions on cable runs is the same. It is possible that a new device will be on the market at some point that will not interfere with the frequency range, but I don't believe it's available yet.

I have at least a130ft run... all signals in the mid 90s (no hd locals though...don't know if that would make a difference).

It's possible, but not recommended to exceed 100ft for new MPEG4 receivers. It is possible your MPEG4 signal quality will degrade the longer the run past 100ft.

Poppycock! I have over 400 feet on my run and I'm still smiling! :D

A power inserter added to the multiswitch location can extend things even farther as it can supply power to the LNBs farther up the line. http://www.sonorastore.com/510.html shows the only one I know of right now.
