Abstract
The present tuning circuit for a trap antenna having a plurality of traps tuned to a predetermined frequency comprises a coil in which a conductive compensation section is electrically coupled to one end of the coil and a conductive tuning section is electrically coupled to the other end of the coil. A pair of rods electrically coupled to the tuning section extend in opposite directions therefrom, whereby the adjustment of the rods and the coil allow the tuning circuit to be operable at a desired resonant frequency. To prevent the detuning of the trap to which the tuning circuit is being attached, the dimension of the compensation section may be adjusted to enable the trap antenna to be operable at both its predetermined frequency and the desired resonant frequency established by the tuning circuit.
