Hello LFers & Lowfers,
Volume 7 of the ARRL Antenna Compendium has an interesting article by John, VE2CV, on an electrically small
antenna for 160 meters. He mentions how a virtual inductance can be created at the top of a tower by means
of "insulating a suitable conductor inside the tower and shorting it to the tower at some judicious length away
from the end." The top loading wires are attached to the top of this conductor which extends above the top
of the tower by some distance.
Has anyone here tried this very interesting approach? I don't recall hearing or reading of this method of putting
an inductor at the top of a vertical section of a top loaded LF antenna. Being more of a mechanical nature rather
than the usual elevated coil, its losses may be less. I might give it a try myself just to check it out.
