Default Omni directional beam :-( ??????

Hey gang, I gotta problem here with a with a 27 kHz. Maco Comet / Y Quad
.......

I bought a new Maco Comet. After assembly, I attached it to a ten ft.section
of tower and a 10 ft piece of thin wall pipe for final adjustments.

Overnight the wind bent the pipe and allowed the director elements to hit
the ground and bend them , so I downloaded the assembly instructions for a
Maco Y Quad and built " it " back in " that " configuration ( by the specs )
to use until I decided what I want to do.
Now here's the problem. I've mounted the Y Quad on the same section of tower
with a new section of pipe and a rotor.

The SWR is around 1.5 to 1, but ............. the antenna seems to make
little or no difference in the direction it's turned or what polarity is
being used ?????????? Its like a "copy stick" ( omni directional )

Now I need to add this ........ This antenna is temporarily located 28
ft.east of a 55 ft, steel tower that has three scanner antennas and a UHF TV
antenna. Also, a tier of three guy wires from the tower are no more than 25
ft, away from, and above it.

Also, several years ago had a "MoonRaker" on this tower and the directivity
and polarity were great !!!!!! just to let you know my location is OK, and
not to suggest that I expect the directivity to equal the MoonRaker

OK. What's the opinion of the group ?? And .......... what suggestions ??

I could try a location ( for testing and adjustments) farther from the
tower, it'd just be a lotta work, but I don't want the antenna put on top of
my tower the way it performs now :-(

Johnny
