At first the converter did not get many stations and I saw some frozen images - but I noticed the message that the signal was weak. I called Access HD to complain. It turns out the FCC's own data shows at least 30% of TV owners will need a new antenna to get a good picture. Access HD identified the correct antenna using a zip code look-up plus a verification using Google Earth (look at surrounding trees and buildings) KINGSTON FLASH MEMORY .
It was awesome. Got the new antenna and I get more stations than I have ever received before - with DVD KINGSTON FLASH MEMORY quality picture. I am sure most of the complaints you hear about converters of all brands are not converter problems at all, but antenna problems! The before and after performance with a good antenna is amazing.
