Hi-Q-Tech pages

These pages will show you the ACTUAL MEASURED Hi-Q antenna Mechanical/Electrical performance.
NOT the Mr. KNOW it ALL gestimation you find published on websites, NOR the results of any mobile antenna shootout’s using Harbour Freight $9.00 DVOM.

This page updated, as NEW projects developed and tested.
