Ensure there is nothing in front of the aerial that could block the signal, such as trees. This bandwidth was chosen to allow reception of a varying frequency, yet also to exclude as much ignition noise from the van's engine as possible. Because of the broadness of the TV transmission bands, and variations in the intermediate frequencies used, a detector receiver could have needed to be tunable between 29 and 240 MHz.

When the two combinations were of equal strength, the van was alongside the house. Fig. Secondly, the propagation of signals at this wavelength and their tendency for confusing reflections from many nearby surfaces meant that the previous triangulation method from a couple of positions was no longer reliable. [viii] To give a narrower directionality, two of these aerials were mounted together in parallel, and spaced apart by 6λ, or six wavelengths at the detected frequency. Electromagnetic noises can be produced by sparking in electrical installations or other sources. The licence was originally issued by the General Post Office(GPO), which was then the regulator of public communications within the … At low frequencies, the large spacing needed required an extension of the van's roof forwards in a prominent box. "[9], Around ten generations of detector van technology were used. £39.99. In contrast to traditional methods of finding the optimal TV signal strength, TV signal meters are considerably easier and typically feature detailed instructions. In radio, a detector is a device or circuit that extracts information from a modulated radio frequency current or voltage. The deflection current was a sawtooth with a frequency of 10.125 kHz. The two networks did not have their line-scan signals accurately synchronised. FAST & FREE. Two new problems needed to be addressed for detection of the new sets: firstly the emissions were both higher in frequency and lower in signal strength than before. The article quoted Ron Smith, who was in charge of the operation, and explained the process: "When a TV set is switched on it gives out a radio signal. At 20° off-axis, the power detected would be half that from the same source on-axis. The receiver circuit was a triple superheterodyne, with the second IF frequency being swept between 60 and 70 MHz, in synchronism with the CRT horizontal scan. In that situation your mobile phone loses the ability to make a phone call. Shop today! Secondly the available signals are now divorced from the broadcast signal.

As the number of broadcast channels in use locally was very small,[vii] only a couple of the mechanically-switched bands would be needed for each detection search. You need to manually fill channel frequency in the meter. The line-scan frequency was generated within the TV as a multiple of the mains frequency and could vary slightly long-term. The second harmonic frequency was chosen as it allowed the use of commercially available radio receivers, whilst avoiding both excessive ignition interference at the fundamental frequency, or confusing long wave radio carriers with the higher harmonics. This is a typical measure for the directionality of an aerial. One of the methods used to identify TV use without a licence was TV detection equipment mounted in a van.
