http://www.trentondistributors.com. I am thinking some of the Canada stations to the east will be received with the HDX1000 on that south facing balcony.
As a Test also put the HDX1000 in the north window for reception of the Canada stations.
Here is a indoor antenna that will receive the Canada stations to the east in the north facing window. Terk HDTVi. Buy the HDTVi where ever you can in Canada.
Using 2 antennas , The HDX1000 and HDTVi , a remote control A/B antenna switch will select the 2 antennas for the Tv connection.
