I installed two Channel Master CM3016 VHF/UHF suburban antennas in the attic of my two story frame colonial. One is aimed at New York City, about 40 miles to my northeast; the other at Philly 50 miles to my southwest). (My exact location- Southeastern Hillsborough NJ, N40° 28.3688', W074° 35.7299', about 10 miles north of Princeton). Antenna 1 hangs from an attic rafter and is pointed at NYC about four feet behind and about nine feet to the left of antenna 2, which is pointed at Philly.
The two antennas are combined (using a splitter in reverse), then immediately split using a second splitter.
A coax runs from the splitter output 1 to the basement, to a cheap Radio Shack 12db VHF-UHF distribution amplifier. It is then splitt four ways- to two digital converter boxes/TV's, one Hauppauge HVR950 ATSC stick/Dell PC, and one stereo FM receiver.
A coax runs from the spltter output 2 to a second spitter, then to two tv's in bedrooms beneath on the second floor (no amp in this branch)
Devices on Antenna: 1 (Zenith DTT901 digital converter, 1 Magnavox TB100MW9 digital converter, and 1 HVR950)
Device on Antenna 2: Zenith DTT901 digital converter
Reception is strong on all stations from both NYC and Philly (including VHF 7, 11, 13 and 6, 12). I did have to play around with the antenna locations to get good reception from both cities; many trips up to the attic until I found the 'sweet spot', but in the end was able to get excellent digital reception from both cities without the need of an antenna rotator.
