</div>The Baden tower is VHF, while all the CN tower stations are UHF (except<br>
CTV). Your best bet would be to massively attenuate VHF signals with a<br>
high-pass filter. I have a UHF/VHF combiner that you could borrow to<br>
test. They are about 10 bucks, and you can just leave the VHF tap<br>
unconnected or connected to a short wire to ensure that nearly all of<br>
CKCO's signal is blocked.<br>
