A fellow posted about his real world, routine, DTV on the alt.video-digital-TV NEwsgroup. With his permission I repost his stuff here: *************************************** o, I don't really see anything bad about mobile TV, I've been doing it for 25+ years anyway. I'll just put in my DTV receiver and watch-a-way. as long as I'm not driving that is. And, btw, It works. I have a bigger inverter now, but still a small 13" color set in the back of my Avalanche, and yeah mobile DTV is alive and well with the USDigital HDTV receiver in mobile use. Well, it ain't High Def, but it works. It does receive HD, but my little 13" ain't. One of these days, maybe I'll get headrest LCD's, but not for a while. I've been doin' it my way ... way to long!

I ahve been doing the same : sort of thing for only 11 years or so, but never live broadcast. : : Thanks, : : Steve It's an amplified (12v) antenna that I purchased from Radio Shack many, many, many years ago (1978). I couldn't tell you the model number if I had to. The antenna slips over the rear window, then you roll the window up to hold it in place. It has two dipoles that extend out over the roof of the vehicle. It has a selector knob so you can "fine-tune" for the best signal. A 75ohm coax attaches to the vcr and from the vcr to the television. I'm thinking about purchasing an inline amplifier, maybe that'll extend my range 5 miles or so, see below. One of these days when DVD's go down in price, I'll put in one of them <imitates old-timer> "new-fangled contraptions."</imitates old-timer> ;) I'll continue with this. With the analog signal you get ghosty, blurry, snowy images as long as you can get a signal. It comes and goes. It's something you get used to. I've been doing this for 25+ years, and I guess that I figure something is better than nothing at all. When you get out of range, you slip in a tape. Back in the day when the speed limit was 55 mph, it took 7 hours to drive from my house to my parents house. I had (at that time) all 3 Star Wars (IV, V, and VI) on tape. My girls would put in Star Wars and watch the whole series during the trip. Great babysitter! I could get television for Dallas/Ft. Worth, Abilene, Lubbock, Amarillo, and Wichita Falls main channels, and pull in translator stations for the boonies around Memphis on 287 and Snyder on 84. With Digital, you got a perfect picture or you don't have any picture. No snow, no fading, just pixilation and poof, it's gone. If you know the area, you know if you'll get it back. If not, oh well, I understand, and go for the tapes, or radio, or cd's. Range is a bit less than with analog for that reason. (say 5 to 10 miles mobile less). Just to let you know, I live in Texas... and have driven from DFW to Lubbock and Amarillo over the past 20 years. I receive a television signal about the same distance you receive a normal FM radio signal. Russ ************************************************************************* I go out 20 towards Sweetwater and then up 84 to Lubbock. I also go 287 towards Wichita Falls and on in to Amarillo. And Around Ft. Worth the only real drop-outs are downtown Ft. Worth with the buildings, but that was ALWAYS the case, nothing new to me. An occasional drop if you go down one of the deeper ... what would you call them, ravines, chasms, valleys?... anyway drop down a hill, but as I said before, that's always been the rule, and It's something that I'm used to. Just the action is a bit different, it freezes and then drops, before you'd get real snowy and shakey and fade away. You actually get a better picture longer now. Russ ************************************************************** : One more question: what fraction of the distance between Ft. Worth and : Lubbock and Ft. Worth and Amarillo can you get DTV from one or another : place? The Ft. Worth stations are of course full power ... but are the : others? Does it make a difference whether they are UHF or VHF? long reply but here goes This was on my last trip about 1.5 months ago. Equipment: USDigital HDTV Receiver from Wal-Mart plugged into a 700 watt inverter (just what I have). (It (inverter) also powers lap-top and other electronics as necessary.) Amplified (12v) mobile diapole from Radio Shack that is >25 years old using 75ohm coax. 13" RCA CRT 120/12v color set using composite video / ausio in for DTV, built in tuner for analog. (no splitter, manually change antenna from STB to TV if changing... better for both analog and digital if no splitter in mobile install... I've tried it, I know.) Ditital Stations listed only West on 20 near DFW 27 and 58 are the worst... only available to intersection of I20 and I30 west of ft worth. (Aledo Hill) ABC (VHF) next fades out about Weatherford. Fox, CBS, NBC, WB, UPN, PBS stations are last to go about the Parker County line. some 30 miles west of my house. This is about 10 miles before the analog signal gives up the ghost. But, it is really in and out by now anyway. Near Abilene You can pick up NBC and CBS about Cisco. (Abilene Stations) and ABC and UPN come in as you enter Abilene (Sweetwater stations). NBC and CBS leave about Sweetwater, while ABC and UPN stay in until Snyder on US 84 Near Lubbock PBS, FOX, NBC come in as you top the hill at Post and stay in until after you turn north on US 385 outside of Littlefield. Near Amarillo West Side up us 60 from Hereford Can begin picking up CBS and PBS (both VHF) near Umbarger, Fox and ABC (UHF) come in near Canyon. East Side FOX and ABC cut out just past Claude (US 287) while CBS and PBS last almost to Clarenton. Near Wichita Falls East Bound on 287 CBS, NBC, ABC, and Fox all come in as you near Iowa Park. West Bound 287 CBS, NBC, ABC, and Fox all come in as you near Bowie. Hope this helps Russ ********************************************************************************* ********************************************************************************** What this seems to mean, looking at maps and the FCC database, assuming that stations with an STA are using them, he gets about 55 miles on a full power VHF, 45 on full power UHF, the Ft. Worth stations. Note that he actually lives about 30 miles away from their 1700 ft HAAT towers. He sees to be getting about 15 miles for low power UHFs. This is with the antenna he describes, rather low to the car. This is about what I would expect. It's true real world experience in the Heartland of America.
