Jack try this one.
Ramp up the power slowly at first though.
Never built one like this, so let us know how it works.

Happy Building Geo>K0FF

Now if I may ask you a question on the practical side.  I'm
>the one with the 80 and 160 mtr Inverted L with the 2:1 SWR.  I checked the
>antennas this weekend and did in fact find that the impedence of the two
>antennas were in the 28 ohm range as measured by the MFJ Antenna Analyser.
>So now I need to build a 2:1 UnUn.  I run about 1200 max .
Can you tell me how to build
>one and what core type/size and size wire I should use
Thanks and 73, Jack W4NF
