Schwarzbeck HFBA 9122 HF-VHF Broadband Balun / Holder

The 1:1 Balun/Holder HFBA 9122 was originally designed as passive field probe to measure very high fieldstrength at low frequencies from 100 kHz up. Depending on the element type in use the HFBA 9122 can be used up to 500 MHz. The charcteristics of HFBA 9122 in the VHF range are comparable to common biconical antennas. The HFBA 9122 balun accepts several biconical element sizes, e.g. BBVU 9135 or BBUK 9139, which allows an antenna factor shift to the desired application. In general the antenna factor rises (reduction of sensitivity) with smaller elements.
