The DF-A0037 is a rugged wideband Direction Finding antenna suitable for harsh enviroment applications. Based on the more portable DF-A0029 product, the rugged version features upgraded mechanical and environmental features to improve performance when mounted on a vehicle.

The antenna has a loop array for good DF performance at low frequencies where the phase size of the array is small. It also has two pentagonal arrays for the middle and high frequency ranges. Secondary pentagonal arrays of dipoles and monopoles provide good omni-directional antennas up to 3.6 GHz when appropriately combined. A HF whip on top of the antenna provides a sensitive omni output for this band.

There is a decagonal cylindrical cavity inside the antenna. It’s approximately 350 mm by 370 mm, allows for switching, amplification and RF processing, thus reducing cable loss and weight.
