The New York City Tv stations/channels are much weaker.
I recommend a channel surfing friendly second antenna system.
This second antenna system is a Separate system and Will Not be connected to the the first system.
For reception of the New York City group of Tv stations/channels install a Winegard HD7084P antenna with a Winegard AP8275 preamp aimed at about 82 degree magnetic compass.
Here is how to aim antennas ,

For connecting the Tv's.
Use a ,

HFS-4D 4 way splitter. Also available at solidsignal.
The 2 Separate antenna systems are separate all the way to the Tv's where a remote control A/B antenna coax switch will be at each Tv location.
Each system will be connected to the inputs of a A/B switch and output the A/B switch connected the Tv.
This 2 Separate antenna systems is channel surfing friendly , push the button on the hand held remote control , change antennas , and keep on channel surfing.
