Hi Jay:
I am actually down near Mount Joy. I just used 'Harrisburg' as a reference since its a bigger city. Yep, if you look at the transmission patterns of the Philly stations, I shouldn't really be able to get them, but with my setup, I can get most of them (except 6-1 (now VHF), and sometimes 57-1 and 12-1).
I use only RG-6 quad shield in my setup.
I may just try the Jointenna 6 to see how it works, plus its pretty cheap.
There are actually a few reasons I don't want to switch pre-amps that I didn't get into in my first post (to prevent confusion).
I have 2 antennas in my attic. A homebrew UHF/hi-band VHF one I made over 25 years ago that still works. I have made some minor adjustments using a network analyzer to tweak it. This one is pointed towards Harrisburg (approx. 20 miles away). The CM 4228 is pointed towards Philly.
I actually have 2 amps, just only 1 power source connected. Both lines (one from each antenna) are separate down to my TV in the family room. In lieu of a switch, I simply plug the 'Philly' labeled RG-6 into the power source for the pre-amp. When I want to watch a H'burg station, I swap out RG-6 and plug that one into the pre-amp's power supply. I know this is a little antiquated, but it works for me. Just never looked for a coaxial switch.
If I changed amps, I don't know if I could still use the same power supply and just change the actual amp at the antenna. If not, I would have to buy 2 pre-amps.
Matt
