Notes:
1. Unless stated otherwise, all performance data computed using Remcom, Inc. X-FDTD 7.0 simulator.
2. Assumptions: PEC, free space, no balun. 300 Ohm transmission line reference.
3. Gain is specified dBi (isotropic) per IEEE definition. Balun and mismatch losses not included.
4. There are two common meanings for Front-to-Back Ratio (F/B). One specifies ratio as measured 180 degrees opposite boresight. The other, used by IEEE

4. There are two common meanings for Front-to-Back Ratio (F/B). One specifies ratio as measured 180 degrees opposite boresight. The other, used by IEEE
specifies the ratio of boresight gain to maximum gain in rear hemisphere. The IEEE definition is the most conservative. IEEE F/B values shown here are
computed based on azimuth and elevation cuts provided in this document.
