Introduction
In January, 1998, the ARRL Board of Directors changed the ARRL advertisement-acceptance policy to permit the advertising of antenna gain figures for antennas whose performance can be accurately modeled using either NEC-4 or Yagi Optimizer modeling programs. To do this, advertisers submit their antenna models for verification by the ARRL Laboratory staff. If the Lab is able to verify that the model accurately represents the design of the antenna, the advertiser may then advertise the antenna gain figures in ARRL publications.
This new policy was introduced in an article that appeared in the April, 1998 issue of QST, "Antenna Ads in ARRL Publications." The full ARRL ad-acceptance policy is found in the Advertising area on the ARRL Web site.
The ad-acceptance policy encourages manufacturers to allow ARRL to make their files available for download. This page contains links to files submitted by manufacturers, along with a number of other antenna-modeling files from various sources.
