I strongly disagree. L.B. bases his recommendation for the 88' dipole on only one factor, the ability to maintain a broadside lobe between 3.5 and 14.5 MHz. That's not the only thing to consider.


1) The longer antenna will have a higher current, particularly at the current maxima. Higher current => more radiation => more gain/higher efficiency.



A short antenna will radiate just as well as a long antenna. Its length makes no difference in the amount of power radiated.

The only thing that changes the gain in a particular direction is changing the pattern of the antenna or changing its efficiency.
Its efficiency isn't going to change very much by changing its length 10% or so.
Getting power to the antenna can be a determining problem though.
