The AH Systems AK-18G Antenna Kit consists of five E-field antennas, one magnetic loop antenna, and two current probes. Each of the antennas and probes are provided with calibrations when connected to a 50-ohm input receiver or spectrum analyzer. Each of the E-field antennas mounts directly to the tripod azimuth and elevation head. The azimuth and elevation head allows the operator to vary the antenna azimuth (direction) and to change the antenna polarity (vertical or horizontal). Cables and an adapter are provided to connect each antenna and probe to either a BNC or N type connector on the receiver. Cable calibrations are supplied. To obtain the field strength of the signal being measured, the operator must add the receiver reading in dBuV, the antenna factor in dB, and the cable attenuation in dB. This yields the field strength in dBuV/m. Calibrations for the E-field antennas are supplied at appropriate spacings (1, 3, and 10 meter) to comply with various specification requirements.
