I was of the understanding 1/2 wavelength and longer don't require a Ground Plane. Whether that's true or not, I can't argue with experience.

I used the original Imax GPK as it may or may not have resolved my RFI issues with the neighbors. As it happens I also added a Fugly Choke Balun at the same time. The Imax GPK was tested/reviewed for validity of purpose and deemed theoretical at best. I never believed it added any benefit in my receive.

Recently I put aside the 4ea x 6' fiberglass radials in favor of 4ea x 102" SS whip antennas lengthened to 103". Several over the hill local region neighbors are now reachable. They could always hear me but I couldn't hear them until now. And I feel the received DX traffic has also increased remarkably; but, that may be entirely imagination.
Only recently have I made my first contact with Australia. Again, it may be conditions were simply in my favor.
