Smart Antenna On-Air Test - 70-miles SE from Mt Wilson (L.A.), outdoors hung on Pergola at 7-ft height, plus about 18-ft above local terrain. Antenna "direction" was optimized prior to taking data. RCA ANT2000 was sensitive to physical direction, DTA5000 not so much and Folded Dipole even less.
RCA ANT2000 vs DX Antennas DTA-5000 vs "calibrated" 0 dBd Gain Folded Dipole (1/2-in Copper Pipe): Folded Dipole was better than either Smart Antenna for CH7-13, the primary target for this test!!!
Although some local UHF stations showed up, NONE could reliably receive Mt Wilson UHF stations.... which shouldn't be that much of a surprise....although a 4-Bay could get about half.
BTW: Winegard YA-1713 10-Element Yagi was the overall winner for Hi-VHF - as expected. Despite limitations of the jury-rigged "steering" mechanism, the YA-1713 could steer a null towards local low power CH12 (only 2.7 miles away), which is co-channel with CH11 and CH13.
Apex DT502 CECB was used for collecting Signal Quality (SQ) and Signal Strength (SS) statistics. Autoscan used for all tests, then tried to improve SQ/SS by manually "steering" Smart Antenna (no help). RCA DTA800B1L was also briefly used to verify consistency of Apex DT502 results.
