I have the Terk HDTVa. It also has a removable amplifier. And it USED TO work very well for distant US signals in my area, at least until the local channels went digital and somehow managed to overwhelm the US signals with their own.
The Amazon.com link you posted didn't ship to Canada. I did not check the 1byone direct shipping since it was down at the time I checked it. Still in principle it seems silly to pay twice as much just because I'm across the border. One perk of Vancouver living I will miss (moved last year) is the border being so close you could even take public transit there and pick up a package.
So to summarize, the availability of brand new ZSS & ZSS-Clones in Canada in early 2015 is quite iffy, and the prices from the U.S. are not only way too high but also are affected by the present day exchange rate, making the price even worse for Canadians.
FYI (time limited) Terk clone availability in GTA @ CNE
If anyone in the GTA is still looking for the terk amplified silver sensor clones there is a pile in one of the liquidation outlets at the CNE in the warehouse outlets section. The outlet has a big banner up that inclues the RCA and Best Buy logos IIRC.
The model is the CHDTVa and they want $27.99 plus tax. (Obviously you have to pay to get into CNE as well so factor that in to your cost).
As liquidation stock they are probably 'returns' or 'reconditioned' so caveat emptor.
I picked one up as a spare (- still using my HDTVa that I bought 4 years ago based upon feedback in this forum and very happy with it despite paying around 2x the price at Bell's TheSource).
They also have amplified Terk flat panel outdoor antennas, a Terk flat indoor antenna, and an RCA equivalent.
Is there any way one of these could be used in a manner that avoids receiving interference from subway trains that pass (above ground) about 60 yards away from an apartment's only window (and in the same direction the antenna must be pointed) ?
This was only about 6 miles away from the CN Tower. A guy had mentioned to me that he had tried once with a cheap indoor antenna to see what channels he could receive, which was as would be expected the Toronto ones, but the subway trains going past every couple of minutes would interrupt and make trying to watch anything pointless. I had a silver-sensor type of antenna sitting unused for about a year that I gave him to try. He said he was able to point it as much away from the subway tracks as possible and see the Toronto stations with the interruptions minimized compared to previously, but still sometimes occurring (along with three Buffalo stations he hadn't received at all the other time). I wondered if there was anything else that could be tried to avoid the interference from the trains. I think if he lived on any of the other three sides of the apartment building and on a higher floor he would probably get the Toronto and some of the Buffalo stations without too much trouble.
I'm on the third floor of an apartment building near Bayview and Eglinton, and I have the same problem with buses going past on the street below, with Buffalo signals. I have a Terk HDTVa, and it's great... but, man, is it picky sometimes.
I'm on the south side of a high floor of an apartment building located south of the CN Tower, and I have the same problem with planes going past over the lake below with Toronto signals.
Despite the planes often passing directly in the way of my line of sight of the Buffalo/Niagara Falls area I very rarely have a problem with any of the normal power level mainstream Buffalo stations.
Since the Toronto stations mostly relay US content, I usually only get irritated with the reception during local news or the odd programme on CBC or TVO.
I also have a Terk HDTVa, and agree that it's great. The upside of its picky sensitivity is you can usually manipulate it to get try and get the specific channel you want at the time you need it. But, it requires forethought if setting a PVR for multiple channels to make sure the antenna is at a good compromise location...
