So what is a good wire lenght that will cover all bands? I have up to
100 feet of wire to work with. looking for 160 to 6 meters but 80 to
160 would be fine.

There really are two separate considerations:

?

1.? Will it "match"?

?

2.? How efficiently is that length of wire RADIATING (or receiving)?the signal on that frequency?

?

I've seen 37 feet listed as a length that would match most - but NOT all - of the bands.? I'd expect radiation efficiency of the 37 foot wire to be very poor on the lower bands, however.

?

It's also going to depend upon your installation and antenna configuration.? Grounding and "RF in the shack" issues are critical.

?

I'd start with the 100 feet, see what that will match and start trimming until I was satisfied.

??

Keep records and share?your results with the group.? Please include the wire size (guage), type, and configuration of your antenna (slopper, inverted L, etc).??

?

"Zip" cord wire?is an inexpensive way to?experiment with wire lengths and antenna configurations.

HI !

Wire length should be something else than half wave to
avoid high voltage feed point and arcing inside the
tuner. Sometimes I had very nice blue shining light
inside my old manual tuner when running higher bands.
(That time I used 600W output and antenna was G5RV)

I made that excel file to see same time all bands
compared to half wave length and wire length.When the
wave length divided by wire length gives something
like 1,15 (2,15 , 0,85 etc.)it is enough far away from
high voltage feed point.

My wire length is 51 m, 10m up and 41m horisontal.
(51m = 167 feet) 41m horisontal is because if changing
later to dipole, it is already right length.
10 meter comes from distance betveen balcony and
horisontal wire. First the vertical length was
something else ( I dont remember anymore) and some
bands where difficult to reach good SWR (less than 2
).
I shortened vertical wire a bit and after that it was
better.After making better ground everything was ok.
My tuner is AH-3, AH-4 is quite similar with longer
wires ( 51m it is not yet real long wire..) .
