What's the best way to find out for what bands (if any) my current

(http://www.amqrp.org/kits/antanal/) or the 'Tenna Dipper
(http://4sqrp.com/kits/kits.htm) answer this question?


These are toys when it comes to the grist of your question. No
analyzer will answer what is best as that is a subjective issue.
Further, an antenna has more characteristics than feed point Z which
impact the nature of your enquiry far more.

A low antenna that warms the ground will look like a charmer to the
analyzer, but then so would your dummy load. Get the idea? You
already anticipate this I am sure.

The old methods, prior to the invention of analyzers, encompassed a
simple sanity/reality check with the field strength meter. Put one
100 wavelengths out and take a reading. Do the same with a buddy in
town. The differences should be telling. This will reveal how much
power has escaped the grip of loss.

Repeat with a DX contact (you and your buddy working the same remote
station). You already have a basis of comparison for line of sight
power levels, you can now determine how well your elevation angles
work out. If you buddy comes in #1 and has a higher antenna, you got
a clue where your next step should be. But higher, lower, whatever,
differences will be revealing. No differences? Well then perhaps
doing some Dale Carnegie courses are in order.
