I presently have a DB-224E as my 'main' repeater antenna.

I have a second DB-224E available to me.

The existing antenna is on a four-foot side-mount at the top of my
now-40-foot tower.  (The tower was a 140' self supporting unit, but
suffered a failure; I am now using the remaining 40 foot 'stub' as the
present position of the side-mounted DB-224E.)

I have a second DB-224E available to me.  I am THINKING of placing the
second antenna on the same side-mount, but mounted below the one that
now extends UP from the 4-foot side mount that is now in place.

1.  Do I mount this antenna 'right side up' or can I simply install it
inverted? (I am assuming that the elements must be top-end-up.)

2.  How can I FEED the two antennas?  (I am thinking of a commercial
POWER SPLITTER, or making up a home-made phasing harness.)

3.  I am also considering a new PATTERN for the antenna(s) as follows:
     A. Arrange the top DB-224E for a bi-directional pattern
     B. Arrange the lower DB-224E as either omni (or bi-directional)

4.  What is (if any) the critical spacing that I should achieve
between the active elements, or when the entire array of eight active
elements is considered?

MY MAIN QUESTIONS:
- AM I FOOLISH in considering this task?  (Is it worth the effort?)
- What would you suggest as the best way to gain coverage, using two
DB-224E antennas?
- Rather than re-invent the wheel, I'd just as soon tap the experience
of you good folks.

Thank you!!
