HF antenna DF-A0015

DF-A0015 implements an 8-element active Adcock Antenna array with a centrally located ninth element for omni-directional sensing. This direction finding adcock antenna array covers a frequency range of 1 MHz to 30 MHz. For improved performance at low frequencies, the DF-A0076 can be installed instead. As well as the 9 elements of the original DF-A0015, this array also features a second array at approximately 4 times the diameter, consequently giving superior DF sensitivity in the 0.5 to 7 MHz band. The arrays are intended for use in conjunction with the Watson Watt (WW) DF estimation method. Corrected WW may also be used to enhance accuracy in the 25 to 30 MHz region. The array features a passive mode where the active matching circuitry is bypassed and powered down. All antenna elements are connected to the central combiner system for beamforming. Shipped in compact storage and transport boxes, the antenna can be assembled by one person in 60 minutes, without special tools or civils. Adjustable feet are located on each element, and as a result, accommodate uneven surfaces. The array is designed for long-term outdoor deployment and is weather resistant.
