[TowerTalk] Non-vertical stacking question

[TexasRF at aol.com]

Regarding Bill's non-vertical stacking question:

In the directions that the antenas deliver in phase signals to the combining 
device, the stacking gain should be there and normal. In the directions the 
signals are out of phase, there wil be a null. In between directions will give 
in between results as well.

This would be a great application to use one of the variable delay line units 
to vary the phase of one of the antennas to allow proper in phase combining. 
There was an ARRL Antenna Compendium several years ago, authored by W5AH on 
such a unit to be used with two vertical antennas. The unit used several relays 
to switch different lengths of coax sections in/out to accomplish the variable 
phasing effect.
