Omarko Posted March 12, 2007 Posted March 12, 2007 hey guys I have Supernet 80GB STB PVR and this is my problem (by the way I had same problem with my previous STB box so its not the device): When I plug in the antenna cable into the wall I get constant glitching and freezing on channels 7 and 10, but channel 9 works perfectly. When I take the antenna out, so its just a coax cable connected to the Supernet, channels 7 and 10 work perfectly but channel 9 is freezing all the time ... I have bought an expensive shielded coax cable but no diff. When I hold the end of the coax going from the STB with my bare fingers, all 3 channels work perfectly. would a device like this help ? link http://cgi.ebay.com.au/ws/eBayISAPI.dll?Vi...p;rd=1&rd=1 can someone help ??? this is crazy ... I am plugging in and out the cable all the time while watching TV ... my wife is just laughing at me and makes jokes of my "latest technology" and usually ends up switching the TV to old ghosty analogue reception I am in Lane Cove so all transmitters are really close ...
Omarko Posted March 12, 2007 Author Posted March 12, 2007 I have been told I need an attenuator, is that right ? is this it - ? http://cgi.ebay.com.au/CATV-20dB-Adjustabl...1QQcmdZViewItem ta
mtv Posted March 12, 2007 Posted March 12, 2007 Omarko, As I advised in your other thread, your signal levels are too high. The attenuator in your link will help, however you can buy them cheaper in Australia (when you take postage into account.) Jaycar sell them, as do specialist TV antenna suppliers like Lacey's TV and DJ Coulter.
alanh Posted March 12, 2007 Posted March 12, 2007 Omarko, Are you in an apartment with a antenna socket on the wall? A lot of apartment blocks use Master Antenna systems, and if they are not designed for digital will not pass channel 6 & 11 as used by channel 7 & 10 analog. How is the ABC & SBS? Read Get the Best Reception, Sydney and read the links. AlanH
Omarko Posted March 12, 2007 Author Posted March 12, 2007 Omarko,Are you in an apartment with a antenna socket on the wall? How is the ABC & SBS? yes I am in a unit block with antenna socket on the wall. ABC and SBS is perfect. whether with antenna connected or without.
alanh Posted March 14, 2007 Posted March 14, 2007 Omarko It would be a good idea to try an indoor antenna. Use the link provided in the Get the Best reception post I refered to above. AlanH

AlanH I have tried indoor antenna, it works, but my wife does not want to have it in the lounge room .... so we are back to drawing board ... I will pick up an attenuator tomorrow eve and post how I went.
Guest Leon Bradley Posted March 23, 2007 Posted March 23, 2007 Ok, Here is the problem in the units where i live. I have both SD & HD Boxes in this unit, both are setup correctly. However, Frequently the Picture & Audio freezes for about 1-2seconds, Its one of the most annoying things. I just want to know, Is it the Antenna on top of the Building causing this?
digitalj Posted March 23, 2007 Posted March 23, 2007 attenuator solved all problems ta Looks like you owe MTV a beer
Guest WhiteRabbit Posted April 3, 2007 Posted April 3, 2007 Help! I am in Lane Cove as well, and it will not pick up Channel 7 at all. The only time my auto tuning managed to find channel 7 it just displayed a blank screen saying "weak signal". I can pick up all the other channels fine, although channel 9 did the same thing at first. I've only had the STB since saaturday. Do I need an attenuator too???
mtv Posted April 3, 2007 Posted April 3, 2007 Quite possibly, WhiteRabbit What antenna are you currently using? If you are in an apartment building with a common antenna, it's possible the distribution system isn't designed for digital reception. There are a lot like that around. As your location is close to the transmitters, an indoor antenna may work ok for you, however, signal levels may still be too high, requiring an attenuator. STB's usually overload when there is too much signal, resulting in data errors. These errors are often confused as 'too low' signal and appear to behave the same way. Attenuators are cheap, so worth a try, unless you pay a pro installer to measure your signals accurately and advise you further.
Guest WhiteRabbit Posted April 3, 2007 Posted April 3, 2007 OK Thanks. I'll go get an attenuator and see what happens. I am in an apartment building, and I have no idea what kind of antenna they have.
mtv Posted April 3, 2007 Posted April 3, 2007 I would suggest a variable attenuator, or a couple of 12dB attenuators, use one for 12db, or both for 24db. It's possible you may even need to attenuate the signals even more, but that's a good starting point. Without actual signal measurements, it's impossible to advise exactly what you need. Let's know how you get on.
