And no you cannot install it yourself.
That is not true at all. I did a self install on a DW6000 purchased off ebay back in july. It's up and running just fine. The fact of the matter is once you have a pin and san number you can commission the modem and hughes doesn't have the faintest idea who installed it.
I bought the equipment on ebay at 3am in the morning for $120. Modem, dish, tria, mount...the whole works. $50 bucks for shipping and another $35 to an authorized hughesnet distributor to set up my account with a pin and san and it was off to the races. So...for just over $200 I was up and running and this is what I'm posting on now.
You DO have a choice of satellites when you commission used equipment. I choose IA-8. You don't necessarily have a choice of transponders that the modem is commissioned on however. While the FCC rules frown on self installs there is a loophole. Have you ever considered all the tripod mount systems that the various RV people and EOC's use (emergency operations centers)? Many of these people are not certified.
On my DW6000 with home account $59.95 a month, hughes says I can get UP TO 500kbps download. I usually run around 575 to 600 kbps download speeds. During peak useage it can sometimes slow down to 100 kbps but that usually doesn't last too long.
However, all that being said unless someone has set up quite a few KU FTA installs I would recommend using a certified installer. For several reasons. The dish is much harder to align than the "pizza pan" DBS dishes. You probably won't have a hughes API which means you will either have to drag a laptop and your modem to the roof with you or make a small adjustment and keep going back to the computer. Even 1/4 to 1/8 inch off and you can loose the signal. Also if the skew isn't dead nuts on the system will never pass ACP and it won't turn on.
But, for someone who has done installs before, is patient, has a rudimentary satellite meter, knows the spectrum as far as what sat is where, reads..understands and follows the hughes installation manual religiously, especially in the area of grounding it can be done yourself. I am living proof and I have a great little setup for minimal money.
OH, BTW...anyone who is thinking of buying off of ebay better do their homework and check to make sure before the purchase that the modem was decommissioned by hughes and is available to be recommissioned will have an expensive pile of junk. If there is money owed on the modem or contract by the previous owner hughes won't enable it. And...don't by a DW4000 system as hughes will no longer commission these units. Only the DW6000, 7000(hs) units can be turned on.
