The purpose of the D.F. Station, Mobile, B.C.
No.2A is to provide an indication of the directional bearing of an indication of a distant
wireless sender, the signals from which are being received on the D.F. The equipment comprises a rotating loop direction finding station entirely
self contained in a 10cwt trailer which may be towed to any required operational site.
Two interchangeable rotating loops (Aerial loop DF "B"
No 5 and "C" No 5) are used to cover the working frequency range of 0.48 Mc/s to
10.0 Mc/s. In addition , there is a vertical rod aerial (consisting of four antennae rod F
sections) which is used in conjunction with the loop aerial in order to provide an
indication of "sense". The vertical aerial is also used for non-directional
reception when searching for a station. |
