J-Vertical for 10 meters - A Slim Jim for 10 meters band

Ground System on a 160M vertical - Ground system measurements on a 160 M vertical by Rudy Severns N6LF

20m T-Monopole - 20m T-Monopole short vertical antenna for 20 meters by AA5TB

A 40m Vertical - This antenna is intended as a simple, inexpensive solution for the newcomer to experiment across the 40m band (7.0–7.2MHz) when only restricted space is available

The Impact of Current Distribution on Array Patterns - Technical Correspondence, QST, July 1990 - Why even "perfect" phased array element currents don't produce perfect patterns.

The simplest phased array feed system that works - How to calculate "phasing line" lengths that actually work.

RF in shack with vertical and longwire antennas - Why a vertical antenna or longwire antenna might require a balun

Build a 2.4GHz Vertical antenna  ^pop - Building a 2.4GHz vertical collinear omnidirectional antenna

A 5 band log periodic dipole array - Modified version of the Telerana antenna which was orginially featured in the July 1979 issue of QST. The array is suspended within a framework made of fiberglass poles emanating from a central hub with the ends tied together with light weight rope around the perimeter. 10-15-20-30-40 meter band coverage

The full-wave loop antenna - These omnidirectional antennas offer Horizontal polarization, and about 2.1 dbd of gain. They are much quieter than a dipole or a vertical, have a broader bandwidth and will usually out perform a dipole antenna.

An automatically tuned 7-30MHz mobile antenna - This is a base-loaded vertical antenna that mounts on the car's roof. The loading coil is designed as a variable inductor, with a three-legged chariot that travels up and down inside the coil, with grooved brass wheels running on the coil turns, and driven by a slotted rotor tube.

PAC-12 Antenna - mobile multiband  ^pop - Here’s an award-winning, easy-to-homebrew, multi-band portable vertical antenna designed by long-time antenna aficionado James Bennett, KA5DVS. He’s documented the design and construction plans for a portable antenna that can be built with relatively ordinary components

A two dollar helical hf portable antenna  ^pop - Here’s an easily transportable vertical antenna for 20 meters collapsible to 4 feet that costs about $2.00 to make. This was created as a fun project to demonstrate how to enjoy operating HF in the field with a home-made portable antenna without spending a ton of money. Bev AH6NF (YL) made this antenna, tuned and ready to operate in less than one hour

Vertical plane antennas' beaming comparision - Animated quad and yagi comparison. You can see antennas' characteristics behavior in a vertical plane with changing of the height.

St. louis vertical updates - The St. Louis Vertical Revisited by Dave Gauding, NF0R here are a few ideas and observations on the St. Louis Vertical

PAC-12 Vertical portable antenna - Build the PAC-12 Antenna a multi-band portable vertical designed by KA5DVS, here’s an award-winning, easy-to-homebrew, multi-band portable vertical antenna designed by long-time antenna aficionado James Bennett, KA5DVS. He’s documented the design and construction plans for a portable antenna

A low cost fishing pole vertical antenna  ^pop - This antenna is based on a 10 Metre long fibreglass fishing pole, by G4AON

Field-Deployable Antennas - Resonant dipoles, the W3EDP and end-fed wires, the extended double zepp, non-resonant doublets, and the "Zip-Cord Special" , the W6MMA vertical.

WA3WSJ antennas - Field amateur radio equipment. Small, lightweight and stealthy antennas. If you operate in the field or want an invisible antenna, you've found the right place. Apartaments antennas. VBWFPA - Vertical Black Widow Fishing Pole Antenna

Hustler antennas - A new tronics company, antenna maker, HF vertical antennas, vhf antennas, cb antennas

K4TR Antennas - K4TR Manufacture and sell simple dipoles, half square 2 wire phased vertical arrays, end fed zepp antennas, G5RV antennas. 1:1 baluns

Butternut antennas - A Bencher antenna divsion, manufacturer of HF YAGI and Vertical antennas

Rotating Tower Systems - Using our components you can build a rotating tower with greater capability than 3-4 static towers. A rotating tower allows common rotation of HF stacked arrays, VHF and UHF arrays, and antennas mounted at optimum heights. Component design also allows tower shunt loading and end support for wire antennas
