10 Element for 432 MHz (Winkler Antennen) by DF9CY
For my return to 70cm Amateur Radio I have been looking around for a short light-weight yagi antenna, which could be rear mounted to the supporting mast. I came to Winkler Antennen who make and sell antennas for good price.

11 Element for 432 MHz by DF9CY
This is a new own design for 2 * 11 element antennas for 432 MHz. It is derived from a design by Rainer Bertelsmeier DJ9BV (20 BVO). I cut it down to 11 elements and have a length of about 1.90m overall for the antenna.

6m/2m/70cm Yagi Antenna Built from Old TV Antenna by KGØZZ
This turned out to be a great little antenna. It works the 6 meter, 2 meter and 70 centimeter bands. You can use one common feedpoint or two seperate feedpoints depending on how you would like to connect this antenna to your transceiver.

70cm Moxon Beam by G3XBM
Do give 432MHz SSB a go sometime and if you think you have no suitable antenna then turn to your wife or girlfriend's wardrobe and search out an old coat hanger.

9 Element for 432 MHz (DK7ZB Type) by DF9CY
I have decided to build this antenna for two reasons: First I wanted to build an antenna of my own, which shall replace the 432 MHz stack of two times 10 Element. Second I want to get some experience in building antennas and check calculations done with the EZNEC+ program.

Cheap Yagi Antennas for VHF/UHF by WA5VJB
These antennas are relatively small, easily constructed from common materials/tools and have surprising performance. The feed method is greatly simpified by directly soldering the coax to the driven element.

Corner reflector antenna by VE3RGW
This design is a periodic plane spaced behind a radiating dipole. The critical factors are the corner angle and the spacing between dipole/vertex ( fold point of reflector ).

Dual Band Tape Measure Yagi Antenna by KM4LGM
While I wait for my Arrow antenna to arrive, I thought I would experiment and build a dual band tape measure yagi since I already had most of the parts on hand.

My Arrow-Style VHF/UHF Portable Satellite Antenna by VE2ZAZ
One of the pleasure of working the amateur radio satellites is making contacts in a portable application and with QRP power. This requires a VHF/UHF handheld FM radio and a handheld 2-band antenna.

Portable UHF 4 elements Yagi Antenna by YO4HHP
Although I’m not a big fan of V/UHF, going over DK7ZB’s website I was impressed by his numerous Yagi antenna design and their good efficiency, and also, myself, eager to do some mechanical construction, I decided to try building this four elements Yagi for 430-440Mhz, to use it this summer in portable operation, mounting hiking etc.

The $4.00 Ham Radio Satellite Antenna by KGØZZ
It's a dual band 2m/70 cm yagi antenna made with common materials and cost very little to make. Also, the antenna is fed with only one coaxial cable and does not use a duplexer.

The 440MHz Slingshot Antenna Project by N9YBP
I needed an antenna with some directivity that I could point east. I saw the Slingshot antenna project on the Hamuniverse website and wondered if it could be cut down to 440 Mhz from 2 Meters.

VHF/UHF X-Beam by KØEMT
I sat down and drew out what I did and thought I'd pass on what I did/found out. The design is from The 1993 ARRL handbook that was given to me by wd0hbx. The x-beam was originally intended as an HF mono-band beam. I used the formulas to build it for 6m. It also happens to work out really well for 2m & 70cm use as well.
