Yes. Also see the Choke Cookbook in k9yc.com/RFI-Ham.pdf  16 turns of a 
4 ft length of two parallel #12 THHN conductors connected as a section 
of parallel wire line makes an excellent choke for 160-30M, and will 
handle a lot of power if the antenna is reasonably well balanced. W8JI 
has shown that a vertical with a folded counterpoise is not well 
balanced (the FCP is electrically short), and high power could fry this 
choke.
