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
