There's lots of measured data in the RFI tutorial on my website. A 16 
turn (x2) bifilar choke connected as parallel wire line  will work VERY 
well on 160-40M.   It will handle legal limit if the common mode voltage 
is fairly low at the point it is inserted. That is, if the antenna is 
reasonably well balanced.
