I had an epiphany last night; all the stations in Lincoln are VHF, while all the stations in Omaha are UHF.  The amplifier for my antenna has inputs for separate VHF and UHF antennas, so I could use the old VHF antenna that used to be on the other side of the house with the UHF antenna on my side, with the two aimed in different directions.  Then I'd be able to pick up 7 additional stations without needing a rotor, giving me about 23 stations total.  Not bad for broadcast TV.

The existing mast is a bit too low.  It's just above the roof line, which is adequate for a single antenna, but not two.  Fortunately, the mast is modular; I just need to insert another segment.  I'm also going to need a new transformer, as the one on the old antenna is not really the right type and is hopelessly coated in electrical tape.   The most biggest difficulty, however, is undoing the guy wires supporting the mast.  I wrapped them up pretty tightly, and I'll have to climb the ladder again to get to them.  I've never been fond of ladders.
