I have a dipole hung from trees in my yard. I am going to lengthen my

just as well to allow the ends to dangle?

=============================

Depending on how much longer your antenna will be, you may notice a modest
improvement in signal strengths on the lowest frequency band. But you might
notice a small decrease in signal strengths on the highest frequency band.
On the other hand, you may notice nothing at all except a change in tuner
settings. But a change in tuner settings can be beneficial.

That is the main thing I am trying to do. The tuning is pretty sharp on
80-75 meters. (the dipole is 96 feet at present) It works okay, but
since I am going to experiment with higher powers, it seemed like a more
forgiving tuner environment might be a big plus. Plus of course not
having to use as much inductance.



I would prefer a Z or C shape. This maintains a high average height for the
antenna and so increases the probabilty of improvement in signal strengths.

Makes sense.

The directions in which the ends are extended will have a slight effect on
radiation patterns which you will NOT be aware of. As your dipole is
non-rotatable it won't matter anyway. For practical purposes, taking one
band with another, you can still refer your antenna as being
omni-directional.

Reciprocity ensures whatever happens on receive will apply equally to
transmit.
