[Elecraft] BL2 w/Multi-Band Dipole

[Ron D'Eau Claire]

It sounds like you are planning to feed a single wire in the center with 450
ohm ladder line so there will be standing waves on the feed line. 

In that case it's *always* more efficient to bring the parallel wire feed
line all the way to the rig and avoid the use of 50-ohm coaxial line in the
system. How much depends upon the SWR, which varies widely with frequency,
and the length of the coax, but you can lose half of your power, or more, in
a coax link with high SWR.

Hello Everyone!

I am planning on building a multi-band dipole fed with 450 Ohm ladder line
soon.  I have a K1 & K2, both with the ATU's installed, and the BL2
switchable balun.  I was wondering if I could connect the balun directly to
the back of the K1/K2 when I use this antenna?  My other option would be to
use one of my 18" foot RG8X jumpers between the rig and the balun.  I know
someone here has done it, or at least knows whether this will work or not. 
I am also posting this question to QRP-L, so I apologize if you see this
message twice.

Thanks ES 73,
