If you put a 500pF cap in a box, with a couple of SO239 connectors so that
it's in series with the coax to the tuner, you'll probably be able to tune
30M.

Adjusting feedline length is another approach.

I am using a Johnson KW Matchbox antenna tuner with a 130 foot long, 30
foot high dipole fed with about 40 feet of ladder (window) line. It
works well on all bands including the WARC bands *except* for 30 meters.
