I will be trying something of an experiment. I took a Zenith DTT901 converter box and put it in my work vehicle today. I know that
ATSC doesn't work in motion, but I am in the car most of the work day and I was wondering if this will work for TV audio while I am parked for lunch. Our local stations have news broadcasts from 11AM to 12:30 PM and I usually take my lunch break sometime during that time period. My DTT901 was sitting in my detched garage and wouldn't get much use this winter anyway, so I decided to Velcro it to a location in the car to keep it from shifting around. For power, I had a spare 12 volt DC to 120 volt AC inverter that doesn't get used very often. So that just plugged into a a spare cigarette lighter jack. For audio, I took an MP3 adapter that has RCA jacks and connected directly to the auxiliary input on my in dash AM/FM stereo. The antenna is the questionable part for my right now. I am going to try a spare FM antenna first that is probably just a 1/4 wavelength of wire that terminates to an F connector. My normal work area is less than 20 miles from the transmitters at Shoreview MN. Anyway, what do you guys here think? Will this be an exercise in futility trying to get TV audio while parked? Also, are there any other antennas that I should be trying? The channels that I will be trying to listen to are:
4.1 (32) = 578-584 mHz
5.1 (35) = 596-602 mHz
9.1 (09) = 186-192 mHz
11.1 (11) = 198-204 mHz
Judging from the frequency ranges, I suppose ideally if I had an antenna resonant at about 195 mHz and 590 mHz, thus a 1/4 wave antenna cut to about 196 mHz would be 3/4 wave at 590 mHz. I will try my random wire antenna Monday, but if that doesn't work I will do some more experimenting. Also, I tried looking at the
FCC records to determine if each of those are using horizontal polarity, but I couldn't tell from the
FCC Database.
