Introduction：
The HHDF 5110A is a 30MHz handheld direction finding antenna manufactured by Schwarzbeck, Germany and authorized by EUTTEST Shenzhen for sales and quotation. This handheld direction finding antenna measures the electric and magnetic fields in the environment and is designed to be used with a suitable portable EMI receiver or spectrum analyzer to locate the position of the radio's electromagnetic field transmitter. The antenna is ruggedly constructed for outdoor use and works well even under harsh environmental conditions. Since its E-plane and H-plane pointing patterns are almost equal, it can measure horizontal and vertical polarization very well.
