I'm a relative newbie to the antenna world, but I'm aiming to get channels from both Washington, DC and Baltimore. If it's possible to get channels even further out (such as Hagerstown or York, PA), I'd be interested in that too. In short, I'd like to figure out how best to upgrade my equipment and where to locate it (attic vs. chimney). I have a limited budget and even more limited expertise. If I can get both DC and Baltimore strongly and cheaply, that would likely be the best option. If I can get the stations that are much further away without too much additional expense, I'm open to pursuing that, though.
Here's my location and setup information:
I live in the Wheaton Hills neighborhood of Wheaton. Unfortunately, I'm near the bottom of one of said hills, and there is substantial tree cover all around my house. The only location that rises above nearly all of the tree cover is on the top of the chimney. The DC channels are 6-7 miles away and at approximately 190 degrees from my location. The Baltimore channels are 30 miles away at approximately 47 degrees.
To date, I've been using a Mohu Plus in my basement and a regular Mohu on the main level of my home. I pull in the majority of the Washington channels using this setup (WRC, WTTG, WJLA, WUSA, WFDC, WDCA, WETA, WHUT, WDCW, WNVC, WPXW). Two low-powered stations (WDDN, WWTD) are inconsistent. I don't receive the other low-powered stations. I have been unable, so far, to get anything from Baltimore.
My antennas are located near windows toward the rear of my home, facing in the direction of the NW DC towers. That is the only direction not heavily surrounded by the trees. I don't have any windowed access in the direction of the Baltimore towers - just the walls, the brick exterior, and a bunch of trees.
Thanks in advance for your advice.
