##  A  50 uh solenoid choke would work..and not series resonate on any ham
band....typ resonates around 40 mhz.

## 16-22 ga magnet wire, wound on a toroid would also work. Then you could
probably achieve > 50 uh, and still not series resonate on 20-10m.

##  The choke could be wired directly across the feed point of the ant.
