Long Cable run

What is the longest cable that I can run for my satellite dish. I need at least 400 ft. To be able to have a clear view of the sky. I hope someone can provide some help.

I am not a satellite TV expert by any means, but 400' of coax is going to introduce a tremendous amount of signal loss that will have to be overcome with some really serious amplification. Whether such amplifiers, which are compatible with satelitte LNB's and pass-thru voltage requirements, are available will require the input of an expert installer.

I think the use of RG11 coax rather than RG6 will probably work just fine at 400 feet. Belden lists their RG11 at 3.84 db per 100 feet at 900 MHz vs 8.3 db/100 feet at 900 MHz for RG6. That would translate to 15.36 db loss for RG11 and 33.2 db for RG6. RG11 at 400 feet is roughly the same loss as RG6 at 200 feet, which is not that uncommon. It could be close but with the possible addition of a powered multiswitch in the house, you should be fine. I'd try it straight from the dish to the receiver first. This is not going to be a cheap installation. You should plan on running 4 cables as well.

If this is a new construction home, you may want to think about mounting the dish to the chimney. I recently completed a house with your exact problem. Wiring feeds into the attic and attaching the dish as high up on the chimney as possible cleared the trees and allowed the dish to collect the signal.

Good luck

There is a huge hill right next to the house covered in trees. Even on top of a 35 foot tower I was not able to get a signal. I figure I would need a 68 foot tower to mount the dish on to maybe get a signal. That is a lot of work and money.

I also have the exact same problem. I have had Directv since 96. When locals came on line I got them. Then they moved the signal to a different Satellite and I lost them - No big deal until now. My TV died and finally I was able to talk my Beautiful Wife into a Sony Bravia kds-50a3000 - now Directv Insatller tells me No Hd because I only pick up 2 satellites - should have 5 - I have a line of sight but it is somewhere between 300 and 400 feet from reciever. Are there any good amplifiers? Will really good cable (rg6 -- rg11? solid copper) do the trick? I dont mind spending a little money upfront if it will work but opinions vary greatly ---HELP----
