Fu.NP.E a/c is a radio direction finder antenna with amplifier and bandpassfilter.
Frequency range is from 0.19 to 25 MHz. Receiver used with the antenna was Fu.H.E.u1.
Fu.NP.E a/c was used both in air and ground operations.

My purpose is to find the position of a transmitter hidden in Maridalen west of Oslo.
The transmitter is a WW2 AGENT SET MODEL 3/II - "BERIT"
It was possible to localize the transmitter with an accuracy of less than 100 meter.
In springtime 1945, one of the secret transmitters of the resistance was hidden in Maridalen west of Oslo.
The germans found them by the use of direction finding equipment. Two of the telegraphers were killed in the subsequent exchange of fire. The third one was taken prisoner.
Both the sender and the direction finding unit that we used were of the same model as those which were used during the war.
