I tried a couple of signal boosting type antennas and returned them all. The Dynalab whip has worked the best of any I have tried. But what really tricked it out was connecting the unit, then walking it around while my wife watched the signal strength meter on my tuner. The spot it ended up in surprised us both. I never would have tried it in that location. Parhaps try it with the one you have. You may find the golden spot in a most unobvious location.
Good luck, John
