I understand the "logic" behind low ERP on VHF stations. I've followed the DTV transition in the US and what a disaster low ERP VHF was down there. Being so isolated, Halifax won't likely have many issues with co-channel interference, even during tropo. Nonetheless, such a low ERP will make the station a challenge at best outside of the city.
It wouldn't surprise me if there's a conspiracy going on here by the stations.
What's the best way to turn off viewers from antenna television? Make the ERP low on VHF, therefore viewers have difficulty getting the signal. And other things as well, such as a defective programming guide, etc.
