Introduction：
BBAK 9137 + VHBB 9124 is a 460MHz biconical antenna made by schwarzbeck company in Germany, which is represented by EUTTEST in Shenzhen for sales and quotation service. This antenna consists of two parts, the balun and the antenna element, which can be disassembled for transportation without affecting the performance of the antenna. The product parameters of this antenna are similar to those of another combination BBVK 9138 + VHA 9103 B, but the coefficients and gains of the biconical antenna are smoother and more stabilized with the balun VHBB 9124.
