Dear George,

The best possible advice I can give you is to visit the Web site of Cecil 
Moore.
http://www.qsl.net/w5dxp/


There you will find tried and true solutions to all-band antenna tuning 
problems. There is no one in the world who has ever published any better 
information directly related to your problem.

Furthermore his solutions aren't pie-in-the-sky solutions - they are the 
real deal.

My question is; how can I make my 270 foot flat-top fed with 200 feet of 450 
ohm ladder line and terminating at a 4:1 balun outside the shack where it 
takes 15 feet, approximately, of 50 ohm coax into the house and to my auto 
tuners, tune the low ends of 160 and 80?
I like this antenna as it is basically a all frequency non resonate antenna. 
I'm fighting putting up dipoles!
I find that my rigs internal tuner baulks at anything below 1.875MHZ on 160M 
and 3.620MHZ on 80M. All other bands and frequencies up to 30 meters tunes 
fine. I do a lot of CW DX'ing.
My question is; If I lengthen the flat top from 270 feet to, say, 290 feet 
will this help my lower ends of 160 and 80? It is extremely inconvenient to 
alter either the ladder line or coax lengths. The flat top is the easiest to 
alter as both ends are on pulleys and I can lower them in minutes.
Anyone got suggestions?
George
