The initial tests on these antennas ( in the APS talk) indicated that the MFJ Long Ranger, which should be as good as the ski pole, was down in power by almost 50%. Surprising. These tests were done at close range, 60 ft, with a directional wattmeter and a relative power slug. No batteries in the meter so this is a close range measurement. Yesterday, I decided to do a 10.3 mi. field test with the rubber duck, the Long Ranger, and the ski pole. Line of sight was poor. I was just going to use my ears to compare but I discovered a way to measure signal to noise without expensive equipment. It is probably publishable in a pedagogic journal. This is detailed in a pdf link below.
Bottom line, the rubber duck did not get in at all. Again, I get the MFJ is down by almost 50% power. The SWR is 2 and only accounts for 10% loss. I don't know if it is the matching section or the telescoping radiator or both that is so lossy. Weird, but at some level I don't care, the ski pole is much more pleasureable to use.
