I have a cottage on the north west side of the Georgian Bay Penninsule, near Lafontaine Beach.
My struggle is the CHCH repeater which sits on the same tower as the Global TV antenna.
Here is a signal report from rabbitears.info based on my estimate of your location:
This is an extract from that report:
This terrain profile shows the hill that you are behind:
The CHCH coverage in your area is weak because they are using a directional antenna that sends only about 1/3 of their power in your direction:
Doing some googling, I found some sites where it shows CHCH-DT-3 as having a virtual channel of 67.1. Is that just old and now replaced by 23.1?
The rabbitears.info report shows CHCH with real channel 23 and virtual channel 67.1
Both antennas feed into a combiner and then CM7778.
What type of combiner are you using, a UVSJ UHF-VHF combiner or a splitter in reverse.
I thought I would register something for CHCH. Would an antenna with a different frequency profile be a better choice?
CHCH is transmitting on real UHF channel 23, so the best antenna for it would be a UHF antenna that has good gain at the low end of the UHF band. It must be aimed at the CHCH transmitter.
They are scheduled to move to channel 28:
It might be worth the trouble to try different locations for the antenna to find a hot spot.
Trees block TV signals, especially UHF signals.
Some users behind a hill have found that tilting the front end of the antenna UP helps, but it doesn't always work. The Antennas Direct 91XG and the Solid Signal HDB91X have a tilt adjustment.
