Modeling an HF NVIS Towel-Bar Antenna on a Coast Guard Patrol Boat. A Comparison of WIPL-D and the Numerical Electromagnetics Code (NEC)

Abstract

A Coast Guard patrol boat high-frequency (HF) near-vertical incident skywave (NVIS) antenna is selected as a test case to compare the electromagnetic modeling programs Numerical Electromagnetics Code, NEC and WIPL-D code. Differences between the models and program outputs will be presents. The radiation pattern predictions will be compared. Agreement between the results is found to be good. Minor adjustments of the two coordinate systems of the programs are necessary. A summary of the comparison is presents.
