Get in on the fun of radio direction finding (RDF) with this<br />
super kit ! The latest in affordable Doppler direction finding<br />
equipment available in a complete kit form ...this one<br />
even includes the receiving antenna assembly!<br />
A must for the “fox hunter” at an unheard of price! Radio<br />
direction finding is a fascinating hobby and is becoming<br />
more and more popular in today's portable world.<br />
With the increasing number of intentional jammers and other unknown transmitters around, Doppler DF locators have<br />
become the rage with a display that gives you a direct bearing on the location of the transmitter. Pretty neat trick considering<br />
you don’t need multiple separate receivers at different locations to triangulate on the mystery transmitter!<br />
The kit includes the Doppler Direction Finder display unit and all the parts necessary to build your own four point, 5 piece<br />
magnetic antenna assembly for easy setup and use. Operates on 12-15VDC and includes a matching 12VDC power plug<br />
for custom integration and connection into your vehicle or portable power supply. Easy to hook up to any FM receiver.<br />
Transmitter (the object of your DF'ing) need not be FM, it can be AM/FM or CW.<br />
