Overview

I've organized antenna resources by type of antenna. Some of the links are to homebuilt projects here and on other sites, and others are to commercial antennas.

Directional - Beam & Yagi

M2 Antennas 23CM22EZ: A 22-element beam for 1.2 GHz operation featuring 16 dB gain.
M2 Antennas 23CM35: A long-boom beam with 18.2 dB gain.
HyperGain 2.4 GHz (ISM) Radome-enclosed Yagi: 14 dBi with a 30 degree beam width.

Directional - Parabolic Grid

HyperGain 2.4 GHz (ISM) Parabolic Grid Antenna:  offered by HyperLink Technologies, the parabolic grids have beam widths that range between 8 degrees and 15 degrees, and 24 dBi to 15 dBi respectively.

Directional - Home built

Express Pizza Antenna: This home-built special is super low cost and can be built in less than 15 minutes, according to its designer, F4DAY.
Helical Aerial for Wireless ISM Band Devices (2.425 GHz): A project initiated by the Canberra Linux User's Group which can be easily adopted by hams (in fact, the project's developers credit the ARRL Antenna book for helical design information).

Vertical

Comet Antenna GP-98: Tri-band base/repeater 5/8 wave on 23 cm vertical for 2m and 70 cm and 1.2 GHz with 9.0 dBi.
Comet Antenna SB-97: Tri-band mobile 1/2 wave on 23 cm vertical for 2m, 70 cm and 1.2 GHz with 9.6 dB gain.
Comet Antenna SBB-94: Tri-band mobile 5/2 wave on 23 cm for 2m, 70 cm and 1.2 GHz with 7.2 dB gain.
Hustler Base Spirit Antenna: 6 dB to to 12 dB verticals for base station use.
HyperGain 2.4 GHz omnidirectional: 8 dBi for frequencies between 2400 and 2500 MHz.

 

Yagi

Quad

Double Quad Antenna: This medium gain antenna is great for mobile and base station use, designed by DL5NEG.

J-Pole

"Baby-J" 1.2 GHz J-Pole Antenna: GHz J-poles? Why not! Check out this little j-pole and build yourself an inexpensive yet great performer for general FM use, by K1JRS. (Link and pictures coming as soon as I get my digital camera back from loan!)
