[SOC] Antenna feedline

[Robert Naumann]

It probably won't make any difference on 40m. Forget the coax if you really
want to use it on 20m.

How are you going to match the 450 ohm line to 50 ohms for your rig?

Hi all,

I'm thinking about putting up a 40 meter dipole between a couple of trees 
and would like to know the current thinking on whether to use coax (RG-8, I 
guess) or 450 ohm 'window' line to feed it.

I'm using a barefoot Elecraft K2 with an auto tuner.  This will be my only 
antenna (at least for now) and I operate on 40 meters about 75 percent of 
the time (CW).  The rest of the time I'm on 20 meters psk31 as well as cw on

15 and ten meters, when they're open.  So for those times that I'm not on 
forty I'll use the tuner.

I've read that the 'window' line is less lossy and a qrp levels I guess 
that's important.

Thanks in advance for any comments you may provide.
