Notes:

1. Pattern computed using array theory and Remcom, Inc. X-FDTD 7.2 simulation of individual element..

2. Assumptions: PEC, free space, no loss in combiner & phasing harness.

3. Gain is specified dBi (isotropic) per IEEE definition. Mismatch losses not included.

4. VSWR measured using HP 8510C Network Analyzer with pole mounted antenna outdoors ~ 10 ft above dry concrete pad.
