Jack,
Have you determined that the radio is actually putting out 100W? The light
bulb test should give some indication. When I first got licensed on HF I
went through a bunch of antennas at less than 20 feet with essentially 0
results. For starters, unless you are DX, nobody will talk to you on 75 or
20 m SSB unless you are 5-9. I made my first contact half way across the
country on 15 m by using a 3 el 6 meter beam at 12 feet (In the attic of a 1
story house). Try getting out during a contest, but you really want to get
the wire at least 30 feet up. I don't think you mentioned what the antenna
is, or what bands you have tried.

 Jack What's the best way to find out for what bands (if any) my
 Jack current antenna is best suited?  Would something like the
 Jack Antenna Analyzer II (http://www.amqrp.org/kits/antanal/) or the
 Jack 'Tenna Dipper (http://4sqrp.com/kits/kits.htm) answer this
 Jack question?
 Richard These are toys when it comes to the grist of your question.
 Richard No analyzer will answer what is best as that is a subjective
 Richard issue.  Further, an antenna has more characteristics than
 Richard feed point Z which impact the nature of your enquiry far
 Richard more.
 That's pretty much what I figured.  I tried to provide a definition
 for best that was more objective than subjective.
 Richard A low antenna that warms the ground will look like a charmer
 Richard to the analyzer, but then so would your dummy load.  Get the
 Richard idea?  You already anticipate this I am sure.
 Exactly.  This is the same antenna that I've mentioned in the past,
 less than twenty feet off the ground and less than five feet from the
 house (which towers over the antenna by ten feet at its highest
 point).
 Richard The old methods, prior to the invention of analyzers,
 Richard encompassed a simple sanity/reality check with the field
 Richard strength meter.  Put one 100 wavelengths out and take a
 Richard reading.  Do the same with a buddy in town.  The differences
 Richard should be telling.  This will reveal how much power has
 Richard escaped the grip of loss.
 While I don't have a field strength meter, I do have a friend with a
 DC-to-daylight receiver.  He was able to receive me loud and clear
 over a mile away.  One hundred wavelengths would be twenty-four miles
 - -- if he had a real antenna, he'd be perfectly situated for that kind
 of test, but all he has is the whip that came with the receiver, so
 I'm not sure that's going to be a valid test.
 Richard Repeat with a DX contact (you and your buddy working the same
 Richard remote station).
 [... rest elided ...]
 Ahahahaha.  Richard, I've worked a DX contact *once*.  That was day
 one of the antenna's life, during the California QSO Party, when I
 logged a contact with a guy in Germany.  I have trouble working people
 several towns over, and in fact have had only one QSO since the
 weekend the antenna was installed.  This part of the test is a little
 optimistic.

 Thanks!
 Jack.
