Hi Guys,

Thank You for all the wonderful ideas on getting my 160-m. Inverted L tuned.  
Your ideas got me going!

My first mistake was connecting the radial ground to my tower ground.  Here's 
what fixed the Inverted L:

1) Disconnected the tower ground from the radial ground and the SWR improved.
2) Put in a new 10' ground rod at the base of the Inverted L and tied it into 
the radial ground and the SWR dropped further to 1.8 @ 1.77 Mhz @ Z=28.
3) Now that the Z was down where it should be I added the 50/25 ohm UNUN and 
presto: SWR is 1.06 @ 1.761 Mhz.

Tomorrow I plan to cut the top of the L a little shorter for resonance at 
1.830.

Hope to work you in the ARRL-160 Test this weekend!

73,
Dick- K9OM
