It almost sounds like an inverted Vee turnstyle antenna except you
normally feed the second Vee with a quarter wave length of 75 ohm cable
between it and the other antenna input if you're using 50 ohm coax to
feed the "array". This provides you with a 360 onmi directional pattern
generally good for the frequencies at which the antennas are cut. I'm not
sure what kind of radiation pattern you're getting just putting the
antennas in parallel and at 90 degrees to each other. Were you feeding
them with open wire line?
