Thanks to "TheSmokinApe" for this excellent discussion of the different variables found with vertical antennas.  A good introduction to vertical antenna theory and practice. Here are some general comments from "TheSmokinApe": In this video, we discuss vertical antennas, ground planes, and radials for ham radio. We also use a tool called MMANA-GAL to do some antenna modeling.

Thanks to Michael Martens (KB9VBR) for this nicely-done Off-Center-Fed (OCF) dipole antenna.  Because of its offset feed, the OCF provides a great match for several amateur radio frequencies, allowing for multiband HF operation Here are some comments from Michael: I build an 80 meter off center fed dipole antenna for this year's ARRL Field Day Event.

If you need a simple, multiband HF antenna, why not try this random length end fed wire project from "SurvivalComms?" The antenna can be used with an antenna "tuner" to get multiband performance at minimum cost. Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

100 watt 7 MHz magnetic loop for units and apartments

If you need a compact, easily-made HF antenna for your apartment or deed-restricted property, then this magnetic loop antenna from Australian radio amateur Peter Parker (VK3YE) should interest you. Here are some general comments from Peter: A description and demonstration of an ultra-simple but 100 watt capability 7 MHz magnetic transmitting loop for units and apartments. There are no hard to get parts or complex workshop skills required to build. Instead of the expensive vacuum variable capacitor, the loop is brought to resonance with a length of RG213 coax (approx 1.85 metres for a 3m circumference loop for 7 MHz). The sliding capacitor's dimensions are not critical but are approximately 6 x 8 cm. As demonstrated performance is excellent and would be significantly better

Thanks to Ray Anderson and Don Nichols (KV4PH) for this fascinating 10 meter J-Pole Antenna project.  This antenna is omnidirectional and has a "small footprint"--ideal for limited or restricted spaces. Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).
