Baltimore or Washington.

I'm in the same area and in the same boat and live in the shadow of a hill
that obscures the line of sight with the big TV antenna complex near the
Sears near Tenleytown. The problem I had with the rotor is that my DVR has
no way to rotate the aerial to the proper direction for the channel I want

They never do, do they?

to record. Since I have two DVRs, I ended up putting two antennas in the
attic: one optimized for DC and the other for Baltimore. I segregate my
recording based on that. Stations coming from Baltimore go to DVR one,
stations from Washington, DVR two.

Very clever. I haven't tried this yet but someone on
sci.electronics;.repair said one could use a splitter (combiner, same
thing) to connect both antennas together, implying that there would be
no problem interactino. No one contradicted him but I never asked
further. I figured I would try it, so there wasn't much point to
discussing it. But I havent' got the omni-directional antenna yet.
Still, I do have that 6 or 8 foot wire.

That works fine. On the same pole I think they should be at least 5
foot apart vertically. Also the wires coming to the splitter from the
antennas should be the same length.
