Biconical Antennas have dipol like characteristics (e.g. circular directional pattern in the H-plane, “8”-shaped in the E-plane, fixed phase center, comparable gain), with an enourmous wide bandwidth, achieved by the double cone elements. One of the earliest and worldwide most popular biconical antenna designs is the BBA 9106 with Balun VHA 9103. During the last years a growing need for expanded frequency ranges arised, which led to the design of biconical antennas reaching down to frequencies 20 MHz and up to 18 GHz and above. A further increase of bandwidth was achieved with qualified 4:1 baluns, providing a typical gain increase of approx. 6 dB at the lower frequency range.
The biconical elements can be mounted and dismounted within a few seconds providing perfect contact repeatability thanks to special clamping fixtures. A small wrench made of insulating material is supplied with the balun, it is tied to the balun head and thus always available whenever needed.
