I routinely have QSOs exceeding 1000 miles (1600 km.) with small whip antennae standing less than 8 feet above a simple ground plane consisting of only two tuned radials. This arrangement is hardly ideal from the standpoint of establishing a station at home or some other permanent place. However, it does represent the ability get on the air and make contacts with only a car battery and five minutes' time for setup. I'm no magician or miracle worker. I do tend to say, "Let's see what happens if ... [fill in the blank]" and sometimes I'm surprised and delighted with the result. Best wishes, "Sal" (really KD6VKW) |

Indeed, but where I came in was to promote discussion as to whether that inefficiency of short antennae was in some way due to the need for coupling into the Universe around the antenna, perhaps a "twist" of the electric field being necessary. Such a twist will be there if there is a half-wave at any time on the antenna, but it would be much smaller if only a fraction of a half-wave were there, as the difference in field to give that twist can only be much smaller. It was a genuine attempt at discussion but was met by tirades of abuse from American rednecks. |
