WHERE USED/FITTED

Fitted with Outfit SD. Quote.....It has been found that when the Bellini Tosi system of aerials is connected to the D/F set by long lengths of lead cased cables, their capacity is usually between 1 and 2 jars and tunes with the aerial circuit to a natural frequency of the order of 450 kc/s. To avoid excessive interference from signals transmitted on 500 kc/s, a high degree of selectivity is necessary and this is obtained by tuning the search coil circuit and coupling it to the tuned grid circuit of whatever amplifier may be in use.
