Topband: Choke Construction Info Needed

[ZR]

It all depends upon how much survivability you want, nothing will survive a 
direct hit.  Any 1.5 to 2.5 mH choke will suffice, just look at the safety 
choke in a commercial amp for the smallest choice.

The big ones are often found in scrapped BCB transmitters and tuning units 
as well as show up at hamfests and on Fleabay as old military gear had 
various candidates.
