Special Conditions For Experimental Wireless Telegraph Station-Non-Radiating Condition

1. The licensee shall, whenever so licensed, endeavour at all times to operate under non-radiating condition and such transmissions may be made at any time and on any frequency authorised in Appendix II.
The apparatus must be such that radiation therefrom will not perceptible outside the enclosure in which the apparatus is installed and no attempt shall be made to send signals to other stations. The transmitting apparatus must be located in an effectively screened enclosure and its aerial output circuit shall be connected to an “Artificial Aerial” whenever possible, so as to confine the radiation within the shielded enclosure. All electric and other wires led into the screened enclosure should be connected through filters to earth so as to suppress any radio frequency currents being conveyed though them to outside. By “Artificial Aerial” is meant a closed, non-earthed circuit arranged as nearly as nearly non-radiating as possible. Any inductance should be in one piece and of small dimensions (as distinct from an inductance of large dimension such as frame aerial). No outside aerial, whether intended for transmission or reception will be led into the screened enclosure, nor will any arrangement by which radiations generated in the screened enclosure may be connected to an outside aerial system, be permitted. The transmitting set shall be permanently located in the screened enclosure and shall not be removed outside it for any purpose whatsoever. Failure to prevent perceptible radiations beyond the enclosure in which the apparatus is situated, will render this licence liable to be cancelled.
Special Condition For Experimental Wireless Telegraph Station-Radiating Condition.

When so licensee, the licensee shall radiate transmissions only authorised frequencies specified, in Appendix III and only at the times and for the period sitiated therein.
