Get in on the fun of radio direction finding (RDF) with this super kit ! The latest in affordable Doppler direction finding equipment available in a complete kit form ..this one even includes the receiving antenna assembly! A must for the “fox hunter” at an unheard of price! Radio direction finding is a fascinating hobby that has been becoming more and more popular in today’s portable world. With intentional jammers and other unknown transmitters becoming more frequent, Doppler DF locators have become the rage with a display that gives you a direct bearing on the location of the transmitter. Pretty neat trick considering you don’t need multiple separate receivers at different locations to triangulate on the mystery transmitter. Up to now, directional antennas with a good front to back ratio (such as Yagi’s or Quads) were required, and were tough to use. However, it’s a little bit impractical to mount a Yagi or Quad to the roof of your car for mobile applications. A much more practical approach to the mobile application is to use four 1/4Wave antennas and the Doppler principal. The kit includes the Doppler Direction Finder display unit, and all the parts necessary to build your own four point, 5 piece magnetic antenna assembly for easy setup and use. Operates on 12VDC, and includes a matching 12VDC power plug for custom integration and connection into your vehicle or portable power supply. Easy to hook up to any FM receiver. Transmitter (the object of your DF’ing) need not be FM, it can be AM/FM or CW. Requires only a connection to your receiver’s speaker jack and radio’s antenna. The whips can be cut and optimized for any frequency from 130-1000 MHz. An easy to build, reliable kit that compares most favorably to commercial units costing upwards of $1000.00! Assembly Required.
