Co-phasing Wheel Antenna
 

Can anyone tell me how I would go about co-phasing or stacking 4 wheel
antennas to improve gain? I am looking at the 33cm band.

Matt

usually putting them in-phase and spacing them a half-wave apart vertically.

Are they big wheels, i.e. 3 full wave loops in each big loop or simply one
loop?
You may want to consider whether you will use a power divider or a phasing
harness.

My old 2 meter big wheels (3 full waves) use a phasing harness and are set
48 inches
apart.( about 5/8 wavelengths). It uses a phasing harness with the coax
going to a center point, splitting into an upper and lower leg. The upper
and lower legs then split again and go to the upper two antennas or the
lower two antennas.

Here is how it is done at 2 meters, you should be able to work it out for
the lengths as the spacing is given in wavelengths. They are about 1.5 meg
for each file.
