No, I am using one of these (R180 at Checkers Hyper):

Which gives a "Fair" signal quality and strength on my decoder, and I get really terrible signal where I am, standard terrestrial TV on that antenna is un-watchable.
With that I get no pixellation of the image, it is just as good as DSTV (SD), and the sound quality is great except on E-TV, which is slightly tinny and echoes. I am going to assume for now that it is problem with their broadcast. SABC 1-3 and Tswhane TV is crystal clear. I have not tried 5.1 surround yet.
I intend to re-connect my grid antenna this weekend (which was cut by either the Top TV or DSTV installer) whose picture was also snowy but not as bad as the bunny ears, and will come back with results, but I expect the signal quality to be better.
