You can try a Channel Master CM4228HD antenna to reach out for those USA Tv stations.
The CM4228HD will not be connected to the CS2V antenna.
Yes the CM3410 can be connected to the CM4228HD antenna.
Or you can get on the pre order list for the New Antennas Direct DB8e , at

It is interesting , the reception of those loooong distance Digital Tv channels.
CBS on REAL UHF channel 39 is being received Ok but the CW on Real UHF channel 32 is not.
You might pick up WNED Real UHF channel 43 PBS.
And WKBW Real UHF channel 38 ABC.
However WUTV Real UHF channel 14 FOX and WGRZ Real UHF channel 33 NBC , will most likely not be received reliably.
Any Tv stations with less signal strength then WGRZ NBC will not be received at all or only very rare reception situations.
It is fun to try for and get those loooong distance Tv stations.
The antenna aiming and location is Experimental.
Moving the antenna to different locations and changing the aim of the antenna can help reception.
A higher gain amplifier will most likely not help with reception , will most likely overload the Tv tuner with strong signal reflections (multipath) be picked up from the buildings.
