Frame antenna with built-in amplifier
In wooden housing with pertinax front and wooden base. On the outside of the housing is an antenna winding with two loops.
Above right is an on/off switch, on the left a light that lights up when the amplifier is on. Bottom left is a wavelength switch for long, medium and short wave (GO, MO and OC). The tuning knob is at the right.
Because the antenna mainly receives the magnetic component of the antenna signal, a large part of the interference is blocked. The built-in amplifier amplifies the antenna signal, so that good reception is also possible indoors.
This type of antenna was especially popular in Belgium and France.
R.R Radio S.A. is founded in Brussels in March 1930 by Messrs Roger Roy and Marc Revol. The address is 10, Impasse de l'Hopital. In 1934 the company moved to a new factory in Anderlecht, 44-46, Rue des Goujons. In 1953 the company moved again, to the Chaussée de Ninove 291. The company makes beautifully designed radios until the beginning of the 1950s of the last century. RR Radio stopped around 1966.

After the loop antenna is connected to the mains, the two plugs on the rear are connected to the antenna and groundbus of a radio unit and a radio station is found on the radio, the antenna can be tuned by means of the right button. By turning the antenna the reception can be further optimized.
Between the on/off switch and the pilot light there are two wire-wound resistors that provide the operating voltages of the amplifier. At the bottom left, the tuning capacitor with next to it the wavelength switch and below the long and medium wave coils. The shortwave coil is situated above the wavelength switch.
