To receive CJNT you will need an antenna with more gain or a higher mast. Another complication is that CJNT is scheduled to move to channel 17, the same channel as CITY. The direction difference between the two channels is 175 degrees. Horizontal stacking can’t null a station that close to 180 degrees ( off the back). A suggestion for CJNT is a pair of 91XG’s stagger stacked one above the other. Stagger stacking increases the front to back ratio by 10-20 dB and adds 2.5 dB forward gain. To stack, move one antenna 3” forward and the other 3” back. (you will need to redrill the booms). The feedline to the antenna moved forward would be 5” longer than the one moved back.
