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