Thanks for the reply. The cable from the main TV is too short to reach my bedroom TV from the wall socket, so unfortunately that's not an option.

Spoke to the electrician today and he mentioned that the new splitter he installed didn't connect easily with the older antenna cables (he had to clamp them hard), so he's agreed to look into some better connection options.

Clamping antenna cables hard is not a good practice, I can make 95% of Cables new or old connect upto new splitters.

Easier solution, re-cable the rooms then you can terminate them easily and connect to new splitter.

 

Really need to check that nothing has been ripped or tugged during previous roof access.

 

Before you do all that, I suggest you get signal level and quality measured at the antenna on all channels and report back once you can establish that the correct antenna is on there for the transmitter being aimed at, you can work on from there.

 

Something has gone wrong if you are suddenly not picking up a channel when you were before.

Thanks for the thoughts. The cable run to my room is through the roof, which is flat tin - there's no ceiling to speak of really and assessing the existing cable would be virtually impossible without pulling the roof off (not gonna happen). We'd have to run a new cable under the house if we wanted to be sure that wasn't the issue.

 

I asked the electrician about measuring signal levels; he said there's no point doing that in metro Melbourne. However he's clearly not an A/V expert, so I'm taking his advice with a grain of salt.

Measuring signals with an appropriate piece of gear is useful in identifying the problem.

 

Regularly fix problems like this - just come back from one now - a beautiful mechanical installation & cabling - pity the brand new cheap **** antenna was stuffed - using an appropriate instrument, took all of 15 minutes to identify & fix.

 

The customer did the right thing, called for a second oppinion, had it sorted, same day service.

Sounds like just what I need. Where are you located? Maybe PM me for further discussion.

No dramas. Can anyone recommend an A/V Tech in SE Melbourne?

The report in the local paper says that TV reception in Rosebud is bad, ...

While I was watching GO last night, every time a particular tram passed my place, the TV picture would break up for 5-10 seconds (similarly for the sound) and wouldn't get back to normal until the tram was well past. It was only one particular tram - all the other trams didn't affect my reception at all. So I suspect there could be something wrong with that tram. Is there anything I can do about it?

I live in the Melbourne Southern suburbs, with good reception of Mt. Dandenong. I have a professionally installed band 3&4 log periodic rooftop antenna that's only a year and a bit old, with a 2 way splitter that was installed at the same time, and pre existing cable. Normally I get a signal strength of 95-96% on the Nine network channels as reported by my TV, and a signal quality that's rock solid at 100%. The installer said I had a signal strength of 58 dBm, I think that's at the wall outlet but not 100% sure.

The tram line is behind my antenna, not in front of it.

Ron,

The cause of the errors in the received signals is caused by arcing between the tram overhead wire and the pantograph on the tram. Possibly the wheel on the end of the pole is worn or the tension applied by the pole is incorrect. The arcing probably will also will affect any electronics on the tram for example the fare collection machine. Find out the number of the tram and report it to the tram company.

Sounds like an issue with the tram, they're supposed to have suppressors but as Alan says, could be a panto issue or someone forgot to refit the suppressor when the tram was serviced etc etc
Was it a new tram or old one?

It was an older one.
