Just moved from one side of Port Melbourne to the other. I've gone from perfect reception on the HTPC to constant break-up and drop outs.

 

Had an antenna guy replace the antenna, install a mast-head amp, and retune. It took several antenna adjustments before I could get channel 7 at all. Now they all tune, but almost every channel pixelates and drops out. 

 

The TV's inbuilt meter (as much as that can be trusted) shows the signal quality dropping all the time from 100% to 50% and lower.

 

Are there any installers out there that won't roll their eyes and blame the HTPC? I'm literally 500m away from where i had 4 uninterrupted years of HTPC bliss.

Hi due to national re-tune and in your case moving location, you may be pointing to the wrong transmitter or translator.

Step one find out which one you need to point antenna to.

Step two, find out the frequencies involved.'

Step 3 do a manual tune to get the correct transmitter tower or translator.

To clear previous tunes, do a auto scan with antenna connector pulled - that will clear old settings.

 

It is best to manually tune the stations you want via the TV tuning menu. Get a tech savvy friend to help.

When tuned to the wrong transmitter pictures will break up like you described. Good Luck

 

Whirlpool has discussion threads, where this problem is being discussed and help suggestions are made :-)

Sorry can't cut and paste the link on this site for some reason. :-(

Thanks but done all that. The installer refused to believe me at first when I showed him the frequencies, but I am getting the best signal from the Mt Dandenong transmitter that's 30KM away, vs the one that's 2km's away. That's if the injector is turned on. With the injector turned off, i get better signal from the City transmitter 2km away. With the injector not plugged in, I get nothing. But no scenario gives me a stable signal.

 

 What concerns me is that because the installer immediately installed a masthead amp, that we were doomed from the beginning. As the two transmitters are in almost the same direction, I fear he has ended up with it in a  bad direction based on mixing signals from the transmission towers to make his signal meter happy rather than understanding what was actually happening.

Sounds like Jim's Antenna's or similar LOL.

 

I would remove the Booster amp. You should not need that. It would kill the transmitter 2km away and more than likely produce problems for the TX 30km away as well.

 

Boosters are known trouble makers in capital cities and Melbourne has TX's on both sides plus translators in the inner city. Amp/booster = disaster. Disconnect it imho.

 

Double check the required frequencies for your needs in the channel listing of your TV.

 

Good Luck and thanks for replying to my posting :-)
