<p>The invention relates to a temperature-compensated combiner comprising a control rod (12) disposed in a combiner housing (11) for controlling the center frequency; a conductor tube (13) secured to the housing and coaxially disposed around the control rod; a regulating tube (14) which is attached to the inner end of the control rod and which is coaxial with the control rod and the conductor tube; and temperature-compensation means (15) for compensating for longitudinal changes exhibited by the unit consisting of the control rod, the conductor tube and the regulating tube for changes in temperature. To reduce the length of the combiner, the temperature-compensation means comprise a temperature-compensation tube (15) which moves the control rod (12) in proportion to variations in temperature and which is disposed within the conductor tube (13) and secured to the inner end of the conductor tube (13).</p> |
