I am sorry to hear some people having bad experience with Mr Antenna.
I am in the Northern suburbs of Melbourne and I had an antenna installed by them recently.
The guy showed up on time, went straight to his work and an hour later job finished and perfect tv reception the end result.
He even discounted his quote by about thirty dollars because I gave him a bit of a hand and a couple of beers for his work.
Aussie made antenna too.
He also gave me his bussiness card to contact him directly if I had any problems in the future regarding the installation.
Top bloke and highly recommended.
Must have been one of the easiest installations on record.
I'd spend at least an hour just performing a site signal survey before any of the installation work.
It's pleasing to hear you are a satisfied customer though.
