Model 3102 is very similar to model 3101 (refer to Item 372) but has a greater frequency range and is smaller in size. The typical gain, 3dB beamwidth and axial ratio data is shown in the handbook. The gain data shown was from measurements with two identical antennas spaced 1.0 metre apart, tip to tip. Construction details are also the same as Item 372. Typical antenna factors are: 1GHz-25dB rising to 48dB at 10GHz.
