A dual band wire beam for 17 and 12 meters - This wire beam Moxon antenna offers double duty on 17 and 12 meters with one 50 Ω feed line by Allen Baker, KG4JJH

Endfed 20/30 Mtr Antenna - Article with detailed pictures of an endfeed antennna for 20 and 30 meter band

K7MEM Center-Fed Half-Wave Dipole ( 3-30 MHz) - A Center-Fed Half-Wave Dipole is probably the simplest of antennas to construct and use. It is usually suspended between two supports, from it's end insulators, and has the feedline hanging from the center.

Better Feedline Loss Measurements with Antenna Analyzers - Various publications through the years have shown how the SWR measured on a shorted (or open) feed line can be used to calculate feed line attenuation

Transmission Lines - About feed lines, parallel lines and coaxial lines, notes on impedance, SWR, Baluns, velocity factor and more by NZART

Eliminating TX RF Feedback Problems - Malfunction of transceivers due to stray RF pickup is a common problem, especially when using end-fed antennas, high-impedance feedlines, or a poor ground counterpoise

Coaxial-feed axiam mode helical antenna - Coaxial-feed axial mode hemispherical antenna is studied experimentally and theoretically

Helical Feed Antennas - Helical antennas have long been popular in applications from VHF to microwaves requiring circular polarization, since they have the unique property of naturally providing circularly polarized radiation. Paul Wade W1GHZ

Antenna Impedance measurement - When experimenting on an antenna it's often important to determine its feedpoint impedance at various frequencies across the operating band. It's easy enough to measure SWR, but sometimes we need to know more detail than this

Super J-Pole for 435MHz - The Super J Pole antenna is a co-linear vertical consisting of a number of half wave length vertical elements separated with half-wave length stubs (Tuning stub) feed with a folded matching stub by vk6ysf

The DBJ-1 VHF-UHF Dual Band J-Pole - Searching for an inexpensive, high performance dual band base antenna for VHF and UHF ? Build a simple antenna that uses a single feed line for less than $10.
