10 out of 10! I have had aerial issue for 10 years and went through 3 different installers who patched over the issues I had. This guy came out and realised that there was something fundamentally wrong with my set-up. He spotted where the others went wrong and lo and behold my aerial wasn't even connected to my internal set up! A quick re-routing to my exiting set up and I have all my channels including RTE absolutely perfect. Quick and inexpensive. Credit where its due.
