x1hdtv--yes, still getting channel 7. Voom upgraded me to the Winegard PR8800, and now I get 2,4,7,9 and 31, plus a bunch of PBS channels and some other stuff that I never watch.
GEBrown--welcome aboard. I'm off the 5th hole of the South Suburban golf course. East of Colorado, and just north of County Line. Your part of Highlands Ranch should have good LOS for OTA. I first had the Stealth, but could not get channel 7. Voom upgraded me for free, and now I get everything. We have an HOA, but they pretty much ignore the OTA antenna and the dish, since neither is visible from the street. I think if you are up front about what you want to put up, and where it will be, the HOA should not put up much of an argument.
On Voom install, as long as you order by July 5th, that locks in the price. The only magic date is your order date--not the install date. When we thought the expiration date for the latest offer was the end of May, a lot of people ordered before the last day of May, but scheduled an installation later in June. You are free to do the same--order by 7/5, and install when ready. Follow this forum--chances are the $0 down offer might be continued past 7/5. Whatever happens, you will find out about it here first.
Lastly, are you sure you need 4 STB's? If you are, I believe the installer is obligated to run up to 4 cable runs at 125 feet per run, so you could have seperate lines to each of the 4 STB's. In my case, I have 4 TV's running on 1 STB. It means that you watch the same channel on 1 TV as you do on another, but it is just me and my wife at home. Whatever you do--make sure that you know how many STB's you really want. If they have to come back to install additional ones after your initial installation, they ding you for $199 per box.
