Folks who can get TWCSC have access to a reasonable source for CBS and PBS HD today (and HBO and SHO) though the cost will make it prohibitive for many/most to have both digital cable and a DBS service.
WOLO-DT: No word yet that I have heard of WOLO-DT on TWC but maybe Bob Davis of this forum can/will provide an update. I bet it is in the hands of the lawyers who won't say much till it is a done deal on their end. (My gut says if it will happen by the Superbowl, that it will be maybe a week before the game).
WIS, WQHB, and WACH might also make it in 2003 so I would think HD is becoming more common if not settled in.
You won't find a SD signal without an ATSC receiver (aka STB) but you might get a hint on reception possibilities if you can get their analog stations (or similar) okay now with an indoor intenna. (most of the towers are in the same general area; so maybe getting analog 10 okay is a harbinger of getting digital 8 okay). (assumes stations at full power too).
This week in Cola I noted that Circuit City has the Zenith HTV420 ($399)which is an OTA only receiver and Best Buy has the OTA only Samsung SIRT-151 ($449) and the DirecTV Model 160 ($699 I think). CC is(was?) giving away a decent indoor UHF antenna (Zenith Silver Sensor; $40 separately) with the Zenith ATSC receiver but it might not work for WOLO which is Ch8 (VHF).... but you never know and rabbit ears might work. BB also had the Hughes E86 DirecTV hd receiver (price not noted).
I can't speak to where to buy outdoor antennas in Cola other than Radio Shack). Be sure to avoid any sold at Best Buy, Circuit City and the like. Do look for Channel Master or Winegard if possible. For internet sales you might consider Starkelectronic
. And hopefully someone else will lead you to a local retailer since antennas still require a bit of luck to get it right the first time. There is a Channel Master/Winegard distributer in Charlotte but I do not know if they regularly serve walk in customers (see CM web site for details).
Have you visited Antennaweb
to see what they recommend for an antenna? Trees, buildings, and hills of course will make it more difficult but these sites are a usefull start. Ardman
is a bit more difficult to work (check the yellow banner ...coverage maps... to start and finesse the filters like checking DT and APP and STA). It can be very useful in determining the distance/direction of the towers you want to receive.
