For reference, I have tuned this exact 88' CF doublet with 75' of balanced feedline with the K2 ATU and it easily tunes on all bands and modeles very well on 40-10.
I used a homebrew 1:1 current balun right before it went into the BNC connector of the K2. Operating in the field on a battery for FYBO in the hail, I drew big static arcs to my EARS through my HEADPHONES until I ran a simple static ground from the K2's GND post to a nail pushed into the soil. What a Shocker! (sorry). I made my doublet AND feedline from 26AWG 19-strand copper weld wire intended for balloon lift that is VERY strong and flexible but doesn't twist or kink and seems to weigh nothing. I highly recommend it for a field antenna: http://www.davisrf.com/ham1/flexweve.htm Bottom of the page, PN "POLYS-26" Good stuff. 73, Steve N4SL __________________________________ Do you Yahoo!?
