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.
