Rubber duckies stock scanner antennas are a trade off. When creating a multi-band rubber duckie you loose something on all bands. The previous advice about the Remtronics antenna is sound but that’s primarily because it’s designed to play optimally on one or two bands. And, as is the case with all handheld stock antennas, treat them as if they were dummy loads. Follow the advice of the group when purchasing an aftermarket antenna. Most multi-band aftermarket antennas are much longer than the stock antennas-they really need to be when considering they must play at resonance on many different bands.
