Hash: SHA1 "Richard" == Richard Clark writes: 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.
