Biconical Elements

Biconical Antenna

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 3 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.
