That is a nice setup. I hope that E1 is being supported by a bracket of some kind - if it takes a fall I wouldn't want to be the one to pick up the pieces....
Re the antennas - do you have an attic? If you can get one or two antennas up there, fed through a splitter, you'd probably hear a bunch more than what you have now. The additional height will help. The E1 would also benefit from stringing something in the attic. It doesn't have to be fancy...
Even if you could get a scanner antenna as close to an outside wall as you can, you would likely be a little better off. Using a handheld with the shortest duckie you have to sweep the area for a sweet spot (most every apartment or condo has at least 1) would be worthwhile. 73 Mike
