Given the vast number of changes in the Canadian markets, it's tough to know what the current situation is regarding which analog stations have been shut down. I picture the TV Fool staff working some looooong hours these days dealing with database edits.
Is CBLN still on the air on channel 40? If so, any consumer grade amplifier would overload.
If you consider only the top seven pending digital database entries, add antenna gain (about 9 dB), it looks like you will be delivering a total of +40 dBmV to the amplifier input. That does not account for any signal from FM or fire/police radio. The CM-7778 is rated for 23 dB gain on the UHF band, and a maximum UHF output of +50 dBmV... that's infers that the maximum input would be 27 dBmV (50 - 23). So, I think the 7778 will overload due to being over-driven by 10 to 15 dB.
Honestly, I think the CPA-19 will be on the edge of overload as well.
