I asked this same question here a couple of months ago, and from what I 
received in answer, I assume unless you have a meter to detrmine inpedance, 
reactance, phase angles, vectors, etc, it is not worth doing to do it right.

So, there is another question I have.  If you just put up 1 vertical and put 
up another one 1/4 wave away, can you use this as a director or reflector by 
switching a coil in and out?

This seems like it would be a lot easier to do.  Thanks and 73
