G3TXQ shows characteristics for common mode chokes

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.
