What kind of cable is it? RG59 or RG6?

WUTV can be hit and miss in the GTA. For me in Markham, it's one of my strongest Buffalo channels. For others at similar distances... barely registers.

At any rate, a preamp WILL be useful for long distance reception. I would recommend a quality model that doesn't overload easily. Also, if you can get your antenna higher that would be good as well... 12-15 feet isn't particularly ideal for doing much more than local pickup.
