[SOC] Antenna feedline

[Art - W6KY]

Tom,
Here is a great article from March 2004 QST on the
classic multiband dipole.
http://www.sgcworld.com/Publications/Downloads/ClassicMultiband.pdf
Use the EleCraft balun for your K2 and you are home
free.
The ladderline will exibit almost 'no' loss at 7Mhz
compared to coax.
I put up one of these with 100' of copper on each side
at about 20' high on one end and 70' at the other.
Worked 53 countries on 160 in about 3 months with 100
watts. DXCC on 80 thru 10. Great wire antenna. 
Hope this helps.. 73, Art  W6KY
