Hi and Welcome,
If that trimmer is connected to the ANT post it's not suppose to be there. The antenna connects directly to the bandswtich to the ant coil. There is a 10K swamping resistor across the primary but no caps. If if measures 21 ohm I assume it going from the ANT post to the chassis. What you are measuring is the resistance of the primary of the ANT coil+ the capacitance of the trimmer.
Very common issue for the model 60 is to have an open primary on the antenna and feedback winding on the oscillator coil.]
