At the end of December, Justin Johnson G0KSC launched an OWA Yagi design site providing free effective designs for Ham Radio operators for bands from 21Mhz to 430Mhz. The OWA (Optimised Wideband Array) Yagi is a very effecient Yagi. Whilst on paper gain figures may appear less than lower impedance designs, no matching device is required resulting in zero matching loss. Add this to design time ensuring high efficiency antennas and the result can be an antenna that radiates 100 Watts of every 100 Watts inserted. Most designs available (all free) have been built and tested. These include dual band, single feed yagi's too. If you want to give building your own antenna a go, visit the site and take a look, you may find a design you could use. www.g0ksc.co.uk Source: http://www.southgatearc.org Adam Jaroszuk Design Coordinator WILEY & CO PTY LTD Level 3, 100 Ipswich Road Woolloongabba QLD 4102 Ph. 61 7 3859 8845 Fax. 1300 385989 adam.jaroszuk@xxxxxxxxxxxx www.wiley.com.au Make Yahoo!7 your homepage and win a trip to the Quiksilver Pro.
