Good morning SpikeRyan,
There is no such thing as a tv antenna that is not "digital ready". The antenna does not care if the signal is digital, analog, standard definition, high definition, etc. TV signal is TV signal.
We have created an add-on for the Sensar antennas that does improve UHF gain, which is being used more now after the transition. For more information please visit http://www.winegard.com/wingman.
