[NLRS] 2M and 450 ohm ladder line

[Cathy James]

Is 450 ohm ladder line practical for 2M feedine?

The loss charts in the handbook and antenna handbook imply that loss 
would be very low.  However, I've heard other sources say that the 
spacing between conductors is too large a fraction of a wavelength for 
proper cancellation to occur.

It would solve some issues I have with getting feedlines out of the 
house if I could use an existing 450 ohm ladder line as my 2M feed.

Alternately, is 450 ohm ladder line acceptable for 6M?
