ABSTRACT:
In the mechanical supporting of the resonator coil it is known to use around the resonator coil an injection moulded plastic U-shaped binder ring, with the loops of the coil running through the arms in the binder ring. The resonator wire can also be wound around a plastic body. The methods of the prior art considerably weaken the Q value of the resonator. According to the invention it is possible to achieve good supporting, without a weakening of the Q value, in such a way that the resonator coil (1) is supported from at least one point by a supporting leg (6) of metal, which one end is fastened to the wire of the resonator coil (1) and the other end is fastened to an insulation piece (8) having low losses, which in turn is fastened to the installation plate.
