I called WYCN-LP the main transmitter for the repeater stations W33AK and W39AR.
http://en.wikipedia.org/wiki/WYCN-LP. General Manager Mark Graham 603-845-1000 , says that W33AK and W39AR are off the air for upgrade from Analog to Digital and will return to the air as Digital stations in a month or so. To days date is 11-12-12.
WCSH-DT REAL Digital UHF channel 44 , virtual number (6.1-2) NBC and Local News Weather.
Is the weakest Tv station signal strength.
I recommend install antenna at about 40 feet.
I recommend install a Winegard HD7082P antenna with a Antennas Direct CPA-19 preamp aimed at about 56 degree magnetic compass direction.
Here is how to aim antennas ,
http://www.kyes.com/antenna/pointing/pointing.html.
As always the starting aim direction is the -> starting aim direction. The antenna can be turned to to find the aim direction for best reception.
For your reception situation that is WCSH-DT 44 NBC.
WMUR-TV 09 , ABC and MeTv , is at 202 degree magnetic compass direction and is a fairly strong digital Tv station at 30.1 NM(dB) and will most likely be received through/at the back angle of the HD7082P antenna.
(W33AK , W39AR , when return to air as digital) , WPXG , WENH , are all Strong digital Tv stations and will be easely received with antenna aimed at 56 degree magnetic compass direction.

In your favor it does not look like there are any trees for some distance to the north east , the direction of WCSH-DT 44 NBC.
As always trees and tree leaves do a real fine job of reducing or blocking Tv reception and so do buildings and other obstructions.
It is best to locate a antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception.
The Tv's Must channel scan for the Broadcast Tv Channels , sometimes named the 'Air Channels' or 'Antenna Channels' in the Tv setup menu because the Tv transmissions travel through the air from the transmitting antenna to the receiving antenna.
DO NOT channel scan for cable tv channels.
