• Notes

• Amplified frame antenna in dark brown and black crackele painted metal case. The rotatable antenna is made of aluminium. Knobs from left to right: wave length switch, direction rotator for the antenna, tuning.

  A connector plug in the octal valve base in the rear of the antenna connects to the output valve of a radio, as the EF41 needs 6.3 volts heater voltage and 250 volts anode voltage.

  The antenna only receives the magnetic component of the antenna signal, thus eliminating most interference.

  There are different versions of this model with minor electrical differences and/or different antenna forms.
