Introduction：
BBVK 9138 + HFBA 9122 is a 320MHz biconical antenna combination manufactured by Schwarzbeck, Germany, and authorized by EUTTEST Shenzhen to provide quotation and after-sales service. It can be used for radiation reception test from 20MHz to 320MHz, and can be used up to 500MHz, but the antenna coefficient will be increased, and the noise of the receiver will be higher, so it is recommended to add a preamplifier above 320MHz.
