The aerial circuit includes a short wave variable condenser which in the 180°position short circuits itself automatically by means of special contacts fitted tothe movable and stationary plates. The secondary coil divided into 10 groups 152 PRACTICAL WIRELESS TELEGRAPHY. is fitted with an end-turn switch which spHts the winding into three completegroups. The secondary winding is shunted by a variable condenser which in thezero position is completely disconnected from the circuit, thereby cutting off the. AERIAL
