Why doesn't the computer modelled antenna work as expected? It could be that the antenna is designed in free space, and you had to mount the elements to a boom to make it. The boom adds negative reactance to the elements. This not a problem on HF, a minor problem on 2 meters , very noticeable on 440 mhz and can destroy a 1.2 ghz design. Ever scale an antenna up from a lower band and have it work poorly? Same problem. BOOM is a handy utility designed to give element correction factors for top insulated elements and elements going through the boom and still insulated. A second page will give correction for elements that are mechanically and electrically attached to the boom.
