I just got my Sammy HLN507W and my Dish 921 hooked up on Wed. I am able to pick up the Baltimore digital stations almost perfectly, but for DC, nada. This is interesting, because I am in Laurel and the DC stations are somewhat closer. According to the 2150 website, most of the DC stations are just under 15 miles to the SW, and the Balt. stations are over 20 miles to the NE.
When I try to tune a DC station the signal strength meter goes from 0 to around 65-70, then immediately changes from locked to unlocked and drops back to zero, all within less than a second. It repeats this cycle over and over. It doesn't seem to matter which station. I am able to pick up their analog brethren OK though.
I'm guessing this might well have something to do with antenna placement as I have a Terk TV44 mounted on my dish on the back (north) side of the house and the peak of my roof is between it and DC. But there are so many other potential causes; e.g. the antenna itself, the signal strength of the stations, and the tuner in my 921 to name a few, I'd like to eliminate as many as possible before spending any more money (or climbing around on my roof in this weather).
Does anyone have any thoughts, suggestions? I have already tried putting an amplifed RS antenna in my front window, but that doesn't seem to make a difference.
I am also in Laurel and it probably depends on what part of Laurel you live in. Although we are closer to the DC transmitters, I think that the terrain makes the biggest difference.
When I first got my STB, I lived in a development near the intersection of the BW Parkway and route 197. In that situation, I had no problems with DC (I had a UHF yagi on the third floor of my home), but Baltimore was harder to get (I had to mount an antenna on the roof). A couple of years ago, I moved to a home that is probably not even 15 blocks from my previous home, and the reverse is true. I can get Baltimore easily, while DC requires the roof top antenna.
In either event, I'm not much of a fan of the Dish mounted antennas. They are not very directional which makes it harder. You should get a rotor and a directional antenna (UHF yagi or bowtie type). This would probably give you the best signals from both markets.
Also, if you look at the antennaweb.org site, I have found it to be a good predictor since it exactly predicts the experiences I've had between the two homes in terms of DTV reception.
