Special Features
Flat-panel, reflector-baxked spiral has not absorber can handle up to 100 watts, fully efficiently, 8dbi gain, provides circular polarisation, very wide bandwidths of 10: 1. Provides signal bi-directional, gain is 3db lower that for the equivalent size reflector-spiral, but remains just as efficient. Has uses for malti-band commnictions in commercial applications such as in-building distributive antenna systems (das) for cellular, wimax and emergency serrvices.
