Ok, figured out the pending applications thing. So CJNT is at -7.1 dB at that height. Looking at the HBU44, it has an 8.2 dB gain. So 8.2 + -7.1 = 1.1 dB noise margin. That's 13.5% over the minimum signal needed to receive that station - not much margin.
CJNT runs at 683 MHz, and your 91XG has a gain of about 17 there, so your NM is about 10, or about 3.2x above minmum signal level. This seems like a more reasonable margin. You could add another Y5713 to the 91XG mast to add CFCF, if you wanted that. Or WVNI is close to 180 degrees from CFCF, so you could maybe use a Y10713 and pick up WVNY off of the backside of the Y10713 pointing at CFCF.
If you will be in the USA, your HOA doesn't have much say in your choice of antenna height. Here are the rules -
