Until about a year ago I was completely unaware that an additional television station, Cape Town TV was launched in the Cape Town area. The station, operated as a non-profit organisation, broadcasts completely free of charge - so if you're in the area and able to see this tower on Tygerberg Hill (they use an analogue signal) - then you should be able to receive Cape Town TV!
To be honest, we're not big on television, so I can't comment on the quality of the broadcasting. I quickly scanned the stations website and found a fairly comprehensive television schedule - which lists the time and name, but regrettably doesn't offer much detail around the nature of the program listed.
Tune in - perhaps you'll enjoy some of the programming!
PS. You don't *really* have to be able to see the tower on the hill... seeing the hill will be good enough. ;)
