AMSAT-SA Dual-band 144\/430 MHz Yagi<\/p>\n<\/div>\n

AMSAT-SA<\/strong><\/a> have made available a new dual-band 144\/430 MHz Yagi antenna for amateur satellite operation.<\/p>\n

The Yagi has a unique element called an ‘Open Sleeve’ which is a director very close to the driven element. The driven element is sized for 2 metres. When operating on 70 cm the ‘Open Sleeve’ acts as part of the driven element on 70 cm (Third harmonic of 2 m).<\/p>\n

The AMSAT SA version is based on a design by Martin Steyer, DK7ZB with modifications by the late Larry Brown, WB5CXC. The first South African version was a collaboration between Guy Eales, ZS6GUY and Gary Immelman, ZS6YI. It was developed for YOTA 2018 where young people successfully used the antenna operating satellites using hand-held transceivers.<\/p>\n

The mechanical structure of the AMSAT SA version was redesigned by Gary, ZS6YI. A choke around the boom was added to isolate the antenna from the coax and reduce the effect human contact has on the antenna. A handle was added on the boom end which makes it more comfortable to hold and further isolates the antenna from the handler.<\/p>\n

The antenna is plug and play. No tools are needed except for soldering on a connector to suit the application. It comes complete in a carry bag with full instructions. This antenna can be assembled and dissembled in minutes. For more details and how to order, visit http:\/\/www.amsatsa.org.za\/<\/a><\/p>\n

SARL and AMSAT SA members get a discount.<\/p>\n
