VHFUHF Yagi Antenna Design Input Use the following entry areas to define your antenna requirements. Yagi UHF Antenna for the 70 Cm Band 430-440 MHz by F4HWK. This is a standard 6 elements design scaled for UHF application.

I like to use the basic DL6WU wideband Yagi designs whenever possible. By Kent Britain WA5VJB edited by John Maca AB5SS Editors notes. Homebrew UHF Yagi for Satellites For successful communication via AO-40 by using the UHF UpLink a Power of 150-200 Watts ERP was necessary ERP is a combination of Rig power output Coaxial loss and antenna gain.

Narrow beamwidth high front to back ratios effective in reducing interference. These antennas were made with this process and tested on this back-yard antenna range. This method of construction can be used on most UHF through low microwave Yagis and is especially useful for the 33 23 and 13 cm bands.

Fully welded 6 element construction. Uhf yagi antenna design uhf yagi antenna design Suppliers. For example a yagi antenna for 50 MHz would have elements that are around 8 – 10 feet 25 – 3 M long.

Specifying a Gain 216 dBd or a Boom Length 39 λ will limit the design to 216 dBd Gain and Boom Length to 39 λ. Nowadays the AO-40 belongs to dead birds but this antenna definitely is useful for any other Satellite like LEOs and also for the next HEO-Sat. Use the following entry areas to define your antenna requirements.

While there are plenty of high performance antenna designs most of the parts required to build them are not available. Specifying a Gain 216 dBd or a Boom Length 39 λ will limit the design. This antenna can be used to receive the ham satellite communications with any portable UHF receiver.
