Several folks asked if I had a decent 10M antenna...
This 8 element Yagi does very well!

One eagle eyed reader noticed a typo in the T-match rod length
in the Note file for my 6 element 15M Yagi (I sure wish YO stored
the modelled matching network parameters, instead of having to manually
type them into the Note file!).  The correct T-match rod length for the
15M 6 element Yagi is 36 inches, not 31 inches.

Use the H key to set the elevation angle to 2.5
degrees.  Use the M and Tab keys to set the
following T-match parameters: 
Rod Diameter:  0.5"
Rod Spacing:     4"  
Rod Length:     24"  
Lead Length      3"
Series Cap   99999 pf   
Feed Z         200 ohms 
When constructing this antenna, the actual driven 
element tip length must be set to 29 inches, the 
length that corresponds to a modelled impedance 
of +j20 ohms in YO
