I Have a few questions on repeater Antennas


Michael Lussier
 

I am looking for some help with antenna questions for my GE MASTRII/RANGR
Repeater
What is the consensus on 4 bay dipole arrays for repeater antennas ? I
have looked into the coverage maps with both the 4 bay dipole array and an
Omni stick. The closest repeater on the same pair is 50 miles away. The
idea of going to the array was to place a null in the direction of the
other system. According to my coverage maps it cleans up and expands my
coverage going to the Omni.
Now for the second part of the question. The 4 bay array antenna have a
phased harness can I put three of them at the same level and the fourth
antenna as a reinforcement in the direction I want ??

Currently the 4 antennas on the array are on the western leg pointing North
and South my coverage is for no better word Terrible
7 miles away to the east I get an S4 , to the west 20 miles an S9

If you are on 2 meters or lower, you can point three in the same
direction and the fourth in another, but the elements cannot be at the
same level (elevation). You will, however, loose gain in the direction
of the three elements by facing one in another and could have a problem
if you are on a large tower. The elements must remain at the required
vertical spacing. At 440 and up, you cannot - they must all point toward
the same direction. You might get away with it at 220.
