Compact Top Band antennas - Modeling compact 160 meter antennas, inverted L, half wave dipoles and linearly loaded dipole

Matching Coil Adjustment - There is a specific procedure which must be followed if proper adjustment of a shunt matching coil is to be achieved.

Loading Coils for 136 kHz - This page starts by showing how to make loading coils for LF, and goes on to describe two of the loading coil assemblies used to resonate the experimental vertical antenna used at GW4ALG.

The Short Dipole Using Coils  ^new - A very popular method of making a short dipoles resonate at a given frequency. This type of antenna is suitable for single band, narrow bandwidth use.

Tee Vertical Antenna for the 630M Band - The conventional configuration was an inverted-L arrangement with the vertical section going up about 13m and then a horizontal top-load wire extending about 8m, the end of which was supported by a tree at about 10m.
