Hi Chuck,
Questions 101...
Why the larger section of welded rod near the
high side of the feed point?
Did you feed yours with a decibel type coax
hardness or a KLM power divider.
[A quick update: KLM power dividers are now
sold by M-Squared (aka M2) antennas here in
California).]
I typo'd the last Email to the other gent...
I suggested he also review the DB-408 antenna
information, which should have read the
DB-411 information.
How much did an article in 73 mag pay way back
then (if you don't mind saying)?
Cheers,
Skipp
