Towards the bottom section of the text:
How far apart in order to phase two 34's? The 34A's could be stacked at 22
to 30 feet apart and XA's 36 to 45 feet apart.?
What is the best height for the 34? The Lowest band usually suffers the
most at low heights. In order for 20 meters to do the best job. it should
be up 45 feet or more. Over 120 feet is questionable because performance
may not be optimum when the band is wide open. A lower height might be
better. 60-70 feet is probably optimum for most applications.
