UHF viewing and television channel selector type

A statistical analysis of the relationship between UHF viewing and television channel selector type is presented. It is based on a data set that contains information on UHF, VHF, and total viewing on over 3,800 individual television receivers, information on the channel selector on each set, and information on receiver, antenna and household demographic characteristics. The data, were assembled from diaries and follow up telephone interviews. An exhaustive examination of this data set revealed no evidence of a systematic relationship between UHF viewing and channel selector type. In particular, no evidence was found that electronic channel selectors are associated with higher levels of UHF viewing. The report concludes that assertions that channel selectors have a substantial effects on UHF viewing should not be accepted in the absence of empirical evidence demonstrating the existence of a relationship.
