Tuner A8 is fitted in conjunction with amplifierM13 for use with a vertical loop aerial.  It must be remembered that when employing this model, better reception will be obtained when the loop is pointed approximately in the direction of the transmitting station.  Good signals will, in fact, only be obtained if the transmitting station is on or before the receiving vessel's bow, or on or abaft her quarter.
