First of all, don't waste your money on a big all-channel antenna like a Winegard HD8200U
or a Channel Master Crossfire 3671 While both are good antennas, you are only interested channels 7, 10, 11, and 13, which are high-band VHF stations. The aforementioned antennas are designed for low-band VHF, high-hand VHF AND UHF. Unfortunately, their UHF parts are not as good as using a separate UHF antenna like the XG-91, and you have no further need for their low-band VHF capability. I suggest using a high-gain VHF high-band yagi like a Winegard YA-1713
plus an AntennasDirect XG-91 mounted above a rotator. Mount the YA-1713 right above the rotator, and mount the XG-91 4' above the YA-1713 on the same mast Use a Channel Master Titan 7777 preamplifier, which has separate VHF and UHF inputs on the mast-mounted preamplifier. Connect the two antennas using coaxial cable to their respective inputs on the preamplifier. Before making any connections on that preamplifier, open the case and find the input selector that allows combined or separate inputs, and slide the switch to "separate. As for mounting, you can attach to a chimney if you like, a gable or use a tripod. Remember, however, that altitude is your friend, and that the higher the antenna system, the better the reception.
Bring you coaxial cable and rotator control cable inside the house. In New England, where basements are common, its customary to find a place in the basement that has AC power available and is equidistant to the two TV sets. Mount your preamplifier power supply in that spot, and mount your coaxial splitter AFTER the power supply. If you have indoor coaxial cable already, and it makes a convenient run to your TV sets, use it, but do not attempt to use twin-lead 300 ohm cable to connect to the coaxial cable.
I usually recommend using a Channel Master 9521a rotator, but I understand that there is a supply issue with them at the moment that makes them hard to find. I suggest using a rotator since you also have the Hartford- New Haven stations available to you as well as the NYC channels, and its always nice to have duplicate networks available in case of preemption of programming.http://www.winegard.comhttp://www.antennasdirect.comhttp://www.channelmaster.comhttp://www.channelmasterintl.com/docume ... lation.pdf
