Optimum length for ladder-fed dipole

I'm planning a dipole installation fed with ladder line and a
wide-range antenna tuner.
I'd like to be able to use it on 160 through 10. A half wave at 160
meters is a bit under 260 feet. Is there any particular reason I
should limit its length to 260 feet? I have enough room to make it
about 320 feet... any particular reason I shouldn' t do that?
Thanks...
RickYou might give some consideration to radiation patterns at the higher
frequencies where greater lengths will produce more pronounced lobes and
nulls and reduce broadside radiation. You might check cebik.com for
further information.

The couple of times I have tried a long antenna like this optimization
of the antenna was mostly finding a length the tuner was happy with on
all bands. IF you have a better tuner than my MFJ you may not have
this problem. Check Cecil's website, Hes the man when it comes to no
tuner antennas.
