Let's go a little slowly here. It is not clear where the reading is
taking place. He states 'if I put a cap across the coax'. Where is the
reading? Across the coax or at the antenna?

He should make the reading at the antenna terminals and add compensation
there so that the VSWR changes from 2.1:1 to approximately 1:1.

I don't have a problem with a 2.1:1 VSWR. I'd leave it alone or retrim
the antenna.

No. The reading you have is an impedance. Impedances are given in
series form. If you shunt this with -j35, you should read 30.6 -j35


If you want to tune out the reactance, put your -j35 capacitor in
series with the load.
