[OKDXA] Balanced Line Feed

[Jerry Chouinard]

Thanks for the input Jay.  I have two of the HFT1500s and use them mainly 
on 75/80 on my contest rigs just never tried them with ladder 
line.  Amazing what a picture in a manual will do for performance!
Yes, glad to have been at HamCom this year and happy we got to see you there.
