Luftwaffe radio equipment ( Funkgerät ) of World War II During World War II , the German Luftwaffe relied on an increasingly diverse array of communications , IFF and RDF equipment for use in their aircraft and on the ground . Most of this equipment received the generic prefix FuG for Funkgerät , meaning " radio equipment " . Most of the aircraft - mounted Radar equipment also used the FuG prefix . This article is a list and a description of the radio , IFF and RDF equipment . Airborne communications . FuG I : An early receiver / transmitter set manufactured by Lorenz . It operated in the 600 to 1667 kHz range ( generally the entire American AM radio broadcast band ) at a power of 20 to 100 watts , depending on installation . FuG II : An update of the FuG 1 , also manufactured by Lorenz , that operated in the 310 to 600 kHz frequency range . FuG 03 : Codenamed Stuttgart , was an airborne receiver / transmitter set used in bombers . Was fitted in : Do 11 , Do 17 E and F , Fw 58 , He 114 , Ju 52 , Ar 66 , Ar 96 , Junkers W 33 and W 34 . Set consists of : S 3a Transmitter ; E 2a Receiver . Power source : G 3 Air - driven generator and 2 - 90 volt dry cells . The FuG 03 operated in the 1 . 250 to 1 . 400 MHz frequencies . FuG 7 : A compact airborne receiver / transmitter used in fighters and dive bombers . Prior to 1943 , it was fitted in the Bf 109C to G - 2 , and Fw 190 A - 0 to A - 3 . After 1943 , it was still fitted in the Ju 87 and Hs 129 . The FuG 7 typically operated in the 2 . 5 to 7 . 5 MHz , with a power of approximately 7 watts . The range of the FuG 7 was approximately 50 km in good weather . Later versions of the FuG 7 included the FuG 7a , which included the S 6a Transmitter , E 5a Receiver and Junction Box VK 5 A . FuG 10 series : A family of transceivers for both R / T and W / T communications . The German FUG - 10 panel , or rack , contained two transmitters and two receivers : One transmitter and its companion receiver operated in the MF or Longwave ; 300 to 600 kHz ( 1 , 000 to 500 m ) range and the other transmitter and its companion receiver operated in the HF or Shortwave range ; 3 to 6 MHz ( 100 to 50 m ) . Most of the FuG 10 series used a fixed wire aerial between the fuselage and tailfin or a retractable trailing aerial wire . The FuG 10P replaced the standard E 10L longwave receiver with an EZ6 unit for a G6 direction finding set . The FuG 10ZY incorporated a fixed loop D / F aerial and a homing device for navigation to a ground station . This loop aerial , usually fitted on a small , " teardrop " shaped mounting , was standard equipment on most fighter aircraft from late 1943 on . Manufactured by Lorenz . Typical power was 70 watts . FuG 16 Z , ZE and ZY : These sets were airborne VHF transceivers used in single - seat fighter aircraft for R / T and W / T communications , and were also used for ground fixes and DF homing on ground stations when used in conjunction with the FuG 10P or FuG 10ZY . Installed for Bf 109G - 3 / G - 4 and later , FW 190A - 4 and later subtypes . Frequency Range was 38 . 5 to 42 . 3 MHz . The FuG 16ZY was also used for " Y - Verfahren " ( " Y - Control " ) , in which aircraft were fitted up as " Leitjäger " or Fighter Formation Leaders that could be tracked and directed from the ground via special R / T equipment . Aircraft equipped with ZY were fitted with a Morane whip aerial array . Principal components : Transmitter , Receiver , Modulator in one case , S 16 Z Tx , E 16 Z Rcvr , NG 16 Z Modulator Dynamotor U 17 Antenna Matching unit AAG 16 Z Modulator Unit MZ 16 Homing Unit ZVG 16 Indicator AFN - 2 Navigation and direction finding . Peilgerät ( PeilG ) 6 : Codenamed " Alex Sniatkowski " , this was a long and medium range D / F set and homing device used mainly on bombers : Ar 234 , Do 217 , Ju 87 , Ju 88A - 4 on , Ju 188 , Ju 290 , Ju 388 , He 177 heavy fighters , He 219 , Ju 88G series are some of the aircraft types to be fitted . Frequency range was 150 to 1 , 200 kHz . A D / F loop made up of a series of metal strips in a " sunburst " pattern was fitted under a round , flush fitting plexiglass cover . A small " whip " aerial was also fitted to the FuG 10 radiomast . Manufactured by Telefunken . FuG 125 Hermine : A VHF radio beacon signal receiver for single - engine , single - seat fighters ; some types of Fw 190 and Bf 109s were known to have been fitted . Frequency range was 30 to 33 MHz ; range using earphones was . Weight was 10 kg ( 22 lbs ) . Manufactured in small numbers by Lorenz in 1945 . IFF . FuG 25a Erstling : This was an IFF set designed to respond to " Freya " , " Würzburg " and " Gemse " ground control radar through the transmission of identifying pulses . The reception frequency range was 125 + or - 1 . 8 MHz . Transmitting frequency was 160 MHz . It could be received at up to . The German Air Force was known to have fitted small aluminum strips which frequently carried explosive charges onto the outside of the equipment aluminium housings . These explosives were linked then by a fuse ( a slow match cord that when ignited , allowed for the evacuation of the crew ) onto any sensitive apparatus , which allowed it to be destroyed rather than be captured by the Allies .
