Bit of a necro post, and yeah, I know ... almost no-one cares (much less watches) SABC or eTV these days, but ... what are people's current experiences with DTT ?
Referring briefly to analogue terrestrial TV for a second : for the past few years I've been noticing that the quality of the Sentech analogue signals - including MNet - appears to have been declining steadily. I have a very good antenna setup and pretty good line-of-sight to the Menlo Park transmitter, but the signal quality really isn't great.
For that reason I've played around a bit with a DiviTech DTT STB which I had on trial for a while. Not with any great urgency, but also without much success, I might add.
...seem like DTT signal was intermittent in Pretoria and now I have no signal...
Interesting. I had exactly the same experience. With the DiviTech STB I get periods of quite good reception (a few seconds at a time), then the picture breaks up and the cycle repeats.
Not sure if that's an infrastructure/transmitter problem or if I have a dud/incompatible STB.
Menlo Park only broadcasts at 40W power... I think you'd need to be pretty close. Try pointing the antenna at the Pretoria tower (S25 41.21 E27 59.02) which broadcasts at 70kW, channel 54 & 58 (UHF). Antenna polarisation is Horizontal.
Another interesting comment, Broadcom. I haven't tried the transmitter at that station (Gelukskroon).
I'd mentally dismissed the transmitter at Gelukskroon because it's so far away from me : 34km versus 4km (Menlo). Didn't realise the difference in ERP was so huge!
I've also looked briefly into
GOtv - partly because that's probably where MNet will migrate to when (or is it
if) the DTT mess gets sorted out.
I was interested to see that Gelukskroon is the transmitter recommended for
GOtv reception in Pretoria. Menlo Park doesn't rate a mention.
