Radio suppression filter kit

Description

Capacitive filters are electronic components known as capacitors or condensers mounted close to the source of radio frequency energy. These capacitors direct the high frequency energy directly to vehicular ground before they can reach wiring that can act as an antenna. Vehicles on which suppression was factory-installed were tested and those which passed had the letter “S” (for suppression) painted on the cowl in blue drab During the war, the radio suppression system was continuously improved to improve efficiency and reduce cost. 1/4-ton trucks had several versions of radio suppression systems between 1941 and 1945. This kit shown in picture is for Willis MB 1944/1945 and late Ford GPW.
