<H1>2M Yagi (144MHz) beam antenna with 7 elements</H1>
<P><FONT face=Verdana><STRONG>Derek Hilleard G4CQM</STRONG> has carried out a
major update of his article comparing three yagi designs for 144MHz.</FONT></P>
<P><FONT face=Verdana>Derek now includes details of a more efficient way of
feeding the OWL yagi.</FONT></P>
<P><FONT face=Verdana>Meanwhile Joe KF7MIX has contributed to the
<STRONG>article*</STRONG> having built the featured 2M7N50 yagi design with a
link to his story.</FONT></P>
<P><FONT face=Verdana>Finally, more N50 yagi designs for 2M, 70CM and 23CM have
been added and all calibrated to NEC-2.<BR></FONT><A

<P><FONT face=Verdana>For this article I have designed from scratch three
State-of-the-Art yagi antennas to highlight the power of YO and to expose some
myths. I make no apology for the fact that I have designed the <B>OCV</B> and
<B>N50</B> yagis for the DX end of the band and so don't recommend these
antennas for general use. However, as further evidence of the power of YO
checkout my two <I>new</I> designs, the wide-band </FONT><A
