A 144 MHz Halo - This halo antenna was built to have an omnidirectional coverage while working in VHF contests. The idea was to have a small but useful antenna for receiving, but it has demonstrated very capable on TX also.

The Joystick Antenna - The Joystick antenna was used many years ago as an all band vertical HF antenna under restricted space situations that would cover from 80 meters thru 10 meters with a tuner and was a great commercial success Some hams even had success with it on 160 meters.

HF insulation, the pitfalls - Although insulation may seem relatively insignificant in the larger picture, on it depends the quality of your performance on air and how long you will be communicating for.

Earth Systems - In order to resonate at a particular frequency, an antenna needs to be at least one half wave length long. Antennas below a 1/2 wave are dependent on a ground system for resonance as well.
