The Marconi direction finder is anadaptation of the apparatus originallyevolved by Messrs. Bellini and Tosi;however, the device as produced bythese inventors was not adapted toship work. Improvements were madeby the Marconi Company and equip-ment is now turned out in a form en-tirely satisfactory for use by naviga-tors, giving, as it does, a high degreeof accuracy. 205. Description of Equipment.—The complete equipment consists of agoniometer with the necessary appliances for control as in Fig. 267, a tuned wire-less telegraph receiver shown in Fig. 268, a tuned buzzer tester as in Fig. 269,and an angle divider as in Fig. Fig. 267—The Radio Goniometer. 256 PRACTICAL WIRELESS TELEGRAPHY.
