Digital TV
I have an older tv and one of those converter boxes I got with the coupon before the "change". I got the box to use at home but I live so far out in the sticks that I didn't get anything, so I tried it in my truck.
Like 2xR said earlier, I have to scan for channels every time I stop for the day, but scans usually only take a minute or two.
The number of channels has varied from 3 or 4 to about 30, but often there are duplicate channels, some in HD, SD, etc. and at some places I don't get anything, like at home.
I have found that position and direction the truck is pointing makes a big difference and that several things can interfere with reception. Other trucks moving through the parking lot cause dropouts in reception and even using my cell phone can disrupt the signal.
I almost always park nose in at the back row of the lot so other rigs don't interfere with reception (and my hood doesn't get torn off), but past experience with a particular truck stop will dictate just where I will choose to park.
The antenna in my truck is built into the roof of the cab/sleeper, for what it is worth.
Overall I can't complain, I get to catch the Cup races sometimes (I am watching the Phoenix race right now) and other times I tune into something that provides that mind numbing white noise in the background.
Your mileage may vary. :twocents:
