Introduction：
BBVK 9138 + VHA 9103B is a 600MHz biconical antenna combo from Schwarzbeck, Germany, authorized by EUTTEST Shenzhen to provide quotation with tax and after-sales service. This biconical antenna element BBVK 9138 and the antenna element BBAK 9137 both have dipole-like biconical antenna directional pattern characteristics. However, the size of antenna element BBVK 9138 is smaller than BBAK 9137. According to the relationship between higher frequency and smaller antenna in the industry, BBVK 9138 has a wider frequency range than BBAK 9137, so this antenna combo can be tested in the range of 60MHz-600MHz.
