a 20' choke in the coax.It's configured as a flat top, approx. 60' on 
each end and 50' at the middle, fed into a big old Dentron Super Super 
tuner in the shack.  On line I find several methods such as the link 
below but would appreciate any suggestions to get it right considering 
it's unusual size.Thanks,Jim - k2hnhttp://www.ke9ns.com/images/g5rv.png

If it's a "double size", won't it tune on 160 as-is?  I have a standard 
G5RV that works well on all bands 80 - 10.

There's one difference with mine:  the ladder line comes all the way 
into the shack, and it's matched there with a parallel tuner.  It works 
a lot better that way than it did with the coax attached.

I strap the feeders and tune against ground on 160.  It's not as good as 
I'd like, but it's easy for an old man
