Yes I have found that my three element 80 meter beam at 190 feet seems to slightly outperform my 30 foot vertical run with a four foot ground stake as a radial. I can easily hear signals that have a signal strength of one milliwatt.
However I am experimenting with a full wavelength 80 meter vertical with 1.3 million pennies as the ground-plane. You have to use the old pennies, as the new ones are copper plated zinc, and will make galvanic noise. For the same reason, the pennies should be spot welded, not soldered, as the dissimilar metals in the solder also cause noise. Also feed line losses become a problem at these low power levels. I want every microwatt of my milliwatt. My tower is located seven miles away from the shack, so I use two parallel twelve inch copper pipes, spaced four feet apart to prevent arcing, and suspended sixty-three feet above the ground by Kevlar ropes to telephone poles every fifty feet. I circulate a mixture of 50/50 distilled water and ethylene glycol through the pipes for heat dissipation, and to prevent freezing. Are you actually a licensed Radio Amateur? You don't sign with your call, and your posted questions are getting progressively more bizarre.
