Very strange that you can receive CHRO (/A\) on 5 but not 43. I am wondering if your bearings are off and you are actually pointing west of CF, either that or something local is blocking the signal from Herberts Corners. Moving the antenna outside may help with that.
The CM4221 is a UHF antenna and will not receive VHF (channels 2-13) especially VHF-LO (channels 2-6) very well, so adding a VHF antenna would help a lot for those channels. VHF antennas are very big, so for indoors, rabbit ears are about your only option, but outside there are better choices. As malstew said, an FM trap may also help, but I would add an antenna that will work with channel 6 first.
