Nothing wrong with experimenting. The explanation of the physics of how that thing works is a matter for debate. In real terms, dinky (with respect to wavelength) antennas are not efficient and do no

are not efficient quarter or half wave Capture area is a product of gain and wavelength, not physical antenna size. Always important to remember that!! If you have an antenna 500 feet long on 20 met

Cable radiation, anyone? I've yet to see a review of a CFA/EH that demonstrated the reviewer understood that possibility, took serious precautions against it, and then measured it. Lacking all that,
