  • Abstract
    By expressing the front fields of the subject conical horn in terms of its gain, and by explicit evaluation of the known GTD expressions for its back field, a concise formula for its front-to-back (F/B) ratio is obtained. The much lower level of back field produced by a corrugated-wall horn as compared to a smooth metallic-wall horn of the same gain is then pointed out.
