Connect a shorted, 1/4 stub across the feedpoint.

3.5 to 4 uH choke from antenna feed to ground ( across the feedpoint
coax ) will both provide a DC path and produce a near 50 ohm match for
the coax on low bands.

Just buy the same ones that mobile antennas have across the feedpoint.
Or wind it on a dowel rod .

Anyway, you get the idea.
