I agree.. for receive I would use multiturn loops or a Flag antenna.

It does make losses more manageable to have the loading inductor near the top, as the guys mentioned earlier; but being a full near-field boundary distance from trees is desirable if it can be done (wavelength divided by 2*Pi). Whereas many hams on the eastern side of the Atlantic are allowed to pump massive quantities of power into a lossy antenna to achieve 1W ERP, if necessary, we will be limited to 200W TPO. Antenna efficiency will be the order of the day over here, I suspect. 73, John Davis
