Simple, resonate the vertical at about 1.9mhz. Then add the inductance across the feed point which may well be in the 2-3 micro Henry region. But use a variable L and slightly alter the L or top loading to get the match where it's wanted. I have used a hairpin match and a T Vertical for a number of years. The only valuation consideration is the vertical design i.e. is it a T or L . T being better, and the quality of the radial system. 73 Clive GM3POI

The other day a ham friend suggested using a coil ("hairpin") to match the low impedance of a well-radialed inverted L to 50-ohm coax. This struck me as a potentially-attractive alternative to a series vacuum capacitor, but I don't know enough to evaluate it.
