1. [TowerTalk] Q factor question... (score: 1): Author: VE2RYY <ve2ryy@globetrotter.net>; Date: Sun, 04 Mar 2007 13:18:56 -0500; I am on the way of building the three element parasitic array on 160 meter according to ON4UN LowBandDxing book. In the array, there is a parasitic element which is a Director...(1.935Mhz) This same; /archives//html/Towertalk/2007-03/msg00034.html (7,302 bytes)
2. Re: [TowerTalk] Q factor question... (score: 1): Author: TexasRF@aol.com; Date: Sun, 4 Mar 2007 14:31:09 EST; Noel, 3.6 uH has a series reactance of about 40 ohms; a Q of 289 equates to a series loss resistance of about 40/289 or about .14 ohms. At 1500w there could be about 6.5 amps of current flowing throu; /archives//html/Towertalk/2007-03/msg00036.html (8,411 bytes)
3. Re: [TowerTalk] Q factor question... (score: 1): Author: Jim Lux <jimlux@earthlink.net>; Date: Sun, 04 Mar 2007 13:26:11 -0800; Let's look at this in actual impedances... 3.6 uH at 1.935 MHz is about 43 ohms. So your Q of 290 implies an AC resistance of 0.15 ohms. What's the AC resistance of the element itself? What's the AC; /archives//html/Towertalk/2007-03/msg00037.html (9,569 bytes)
