Thanks everyone
Yes, all the Vancouver stations are UHF. For me, my local stations could probably come in with a piece of hay wire.
With the big frequency auction in the US, according to Industry Canada, they will not make any stations here switch from UHF to VHF, or vice versa. I was planning on waiting a bit to see if any of the Bellingham stations might be reassigned to VHF. I believe UHF 37 will be the new top end of the OTA broadcast spectrum, so eventually up here a few channels will have to be reassigned to lower UHF frequencies. Apart from having two smaller antennas replace mine with a rotor, it might be overkill, but I think a db8e could be adjusted to both transmitter azimuths.
