First off, your existing antenna, if it's anything like the RCA that it appears to be like, is a miserable antenna. It's about the worst of the indoor antennas I've ever tested for UHF. Surprisingly, it's much better on high-VHF.

I wouldn't rule it out, but you'll need to do a few things right and get lucky on several others. The math says it *might* be doable.

Note that the azimuth to Syracuse is ~165 true. Can you avoid the tree in front of the house from your window and "see" the horizon in that direction?

Does your window have any of the following: Aluminum screening, low-E coating, metal grids?

Do you or any adjacent neighbors in the building with a balcony or patio or a spot in the yard that offers a good view in the required direction where you might throw up an antenna on a tripod or a mast in a 5 gallon bucket (sand or gravel to weigh it down) for a short period of time?

Using an amplifier is probably going to be necessary, but, due to the proximity of the channel 11 tower, care is going to be needed. You're going to need to suppress that station so it doesn't overload the system.
