Herb >> A good way to test a TX antenna is to listen to one of the many SDR receivers available on line <<
We can use the reverse beacon network. RBN, select DX spot HF > 160m http://www.reversebeacon.net/dxsd1/dxsd1.php?f=3 The SDR return the signal intensity in db and you can compare with other callers at same time. Also RBN keep a report archive you can download raw data, using excel you can filter band and time. http://www.reversebeacon.net/raw_data/ This feature allow you to run A/B test and later download the results, just keep record of the time you switch A or B antenna. Another advantage is to know if the band is open, thing not so common nowadays, I don't raise a skimmer in EU for several weeks, JA, ZL or VK since August.
