Better to keep things simple by enabling the T3200 antenna and hiding the SSID broadcast. By default the Telus Optik SSID is hidden, so you would only be hiding the public broadcast.
Another way is to leave the T3200 antenna OFF and get a Ven501 Access Point from Telus and connect it to the T3200 (hardwired). The access point will broadcast a hidden SSID just like the T3200, and of course it's also compatible with multicast traffic from STBs.
