The Antenna Holder / Balun with cascaded matching baluns is primarily designed for the use with biconical elements such as BBA 9106 or BBAL 9136. It may also be used with rod elements as a dipole with improved bandwidth. The VHBB 9124 Balun provides an extraordinary degree of symmetry (common mode rejection), especially at the low frequency end (20 to 40 MHz), where otherwise lack of symmetry with a cable braid current may cause a severe error. Biconical antennas are generally mismatched at low frequencies and show a negative gain. The worldwide popular dipole VHA 9103 with BBA 9106 bicones provides at 30 MHz an antenna factor of 19 dB/m. The same biconical elements in this 200:50 W VHBB-Balun is 5 dB better in gain and shows a "more sensitive" antenna a factor of 14 dB/m.
