Although you did not state it, I assume you are testing these antennas through a length of coaxial cable- unless you account for the cable's electrical length and loss, the readings will not be accurate. Dale W4OP I've tested the other antennas (HF and VHF) at the end of the coax with the analyzer and they show the same results as on the air tests with the wattmeter. When I switch to UHF, the results are completly different between my on the air tests and the analyzer. I'd say this is a good indication of a problem. I also tested one of the UHF antennas at the antenna, with a small jumper, about 8 feet in length. |
