Page 4: General Information
GENERAL DESCRIPTION The AK-571-4 Horn Antenna kit is the newest member of A.H. Systems family of antenna kits. This Antenna Kit provides a convenient solution for increased frequency requirements from 700 MHz to 40 GHz. As specifications include higher test frequency requirements so does the need for an accurate antenna solution. - Page 5 A.H. Systems AK-571-4 Horn Antenna Kit and re-attached to the antenna. (The bracket is not needed for mounting if the tripod being used has an Azimuth/Elevation Head.) Operation: Attach the antenna to the tripod azimuth and elevation head through the hole on the antenna bottom or the hole in the mounting bracket.

A.H. Systems AK-571-4 Horn Antenna Kit OPTIONAL EQUIPMENT The AK-571 case comes with two additional cutouts for optional preamplifiers. In order to improve overall system sensitivity, the following equipment may be required: PAM-0118P with an SAC-18G-0.5 PAM-1840 with an SAC-40G-0.5 PAM-0118P Preamplifier 20 MHz –... - Page 7 A.H. Systems AK-571-4 Horn Antenna Kit head come in their own carrying case. Each tripod leg is independently adjustable in angle and length to facilitate antenna height setting. The tripod legs have a rubber tip on one end for indoor or hard surface use, and a metal spike on the other end for outdoor soft surface (such as dirt) use.

Systems AK-571-4 Horn Antenna Kit ANTENNA FORMULAS AND CALCULATIONS EMISSIONS TESTING Individual calibration data for the log periodic antenna is supplied at appropriate distances (3, and 10 meter) to comply with various emissions test requirements. For emissions measurements, add antenna factor plus cable loss to receiver reading in dBV to convert to field strength in dBV/meter.
- Page 12 A.H. Systems AK-571-4 Horn Antenna Kit dBmW/m = dBV/m - 115.8 The constant in this equation is derived following similar logic. First, consider the Poynting Vector which relates the power density (W/m ) to the electric field strength (V/m) by the following equation.
