Open Conical / Collapsible Elements

Open conical elements offer the versatility of adjustable opening angles, providing similar performance to biconical elements with circular H-plane and “8”-shaped E-plane patterns. Their key advantage lies in improved performance at lower frequencies through the use of extensions. Models like the BBFA 9146, FBAB 9177, and FBAL 9178 are foldable, making them highly portable and space-efficient during transport and storage, ensuring convenience without compromising on performance.
