The equipment used a directional aerial in the rear fin for both transmission and reception. The AN/APS-13 ( also referred to as the RT-34 or ‘Monika’ MK.7) was a tail warning airbone radar detector designed to warn the pilot of an aircraft of the approach from behind them of another aircraft, between the range limits of 200 and 800 yards. Used in the rear tail of Second World War bomber aircraft such as the B-17 bomber and also in British bomber and fighter aircraft after the Second World War.
