Shortwave Antenna for the "Super Six"

ewe We have received many inquiries from owners of "Super Six" receivers asking for censtructional details of the short-wave frame antenna. Previously we have not thought this worth while, as this component can be obtained commercially at a quite reasonable price. However, for those who prefer to make their own, we publish the following details :- :

Twelve turns in all are put on, and they are wound in saw-cuts made approximately 1-8i1. apart in the four arms, All further details are given in the sketch. Owing to the smallness of the antenna, it will be found that tuning on both the: aerial. and oscillator condénsers, is rather critical, and for this reason slow-motion dials of gddd quality are a necessity,
