1. [Towertalk] OWA Yagis (score: 1): Author: kk9a@arrl.net (kk9a@arrl.net); Date: Sat, 13 Jul 2002 08:43:24 -0500; Does anyone have any experience with the OWA design yagis. Is there any advantage other than low SWR and direct 50 ohm feed? I modeled the 15m 6el X 36' boom and compared it to my DX Engineering 15DX; /archives//html/Towertalk/2002-07/msg00364.html (7,239 bytes)

3. [Towertalk] OWA Yagis (score: 1): Author: sm2ekm@telia.com (Jan Erik Holm); Date: Sat, 13 Jul 2002 18:15:33 +0200; As far as I remember OWA=optimized wideband array, that would explain it all! Why in the first place use a OWA design on 50 MHz? Not needed with so narrow band. 73 Jim SM2EKM --; /archives//html/Towertalk/2002-07/msg00372.html (8,256 bytes)
4. [Towertalk] OWA Yagis (score: 1): Author: btippett@alum.mit.edu (Bill Tippett); Date: Sat, 13 Jul 2002 16:45:12 +0100; KK9A: advantage other than low SWR and direct 50 ohm feed? I looked at the OWA when I was considering retuning my KLM 610's. I could see no significant gain or bandwidth difference for the same boom; /archives//html/Towertalk/2002-07/msg00374.html (7,378 bytes)

[Towertalk] OWA Yagis (score: 1): Author: n4kg@juno.com (n4kg@juno.com); Date: Sat, 13 Jul 2002 11:03:05 -0600; Generally speaking, the higher the gain, the lower the Feed Impedance for a split dipole feed. When antennas are tuned to produce a 50 Ohm feed, they give up some gain. The TA33 is a 'classic' exampl; /archives//html/Towertalk/2002-07/msg00375.html (8,702 bytes)
6. [Towertalk] OWA Yagis (score: 1): Author: Mark <AA6DX@arrl.net> (Mark); Date: Sat, 13 Jul 2002 22:43:08 -0700; Lots of folks have a problem with the Classic beams having a longer driven element VS the reflector .. due to the feed via coax inserted into the driven element. I do not see a REAL loss of gain via; /archives//html/Towertalk/2002-07/msg00384.html (8,542 bytes)
7. [Towertalk] OWA Yagis (score: 1): Author: n4kg@juno.com (n4kg@juno.com); Date: Sun, 14 Jul 2002 01:10:57 -0600; The gain loss is NOT due to the classic feed (actually a clever idea). The gain loss in SPLIT DIPOLE FED antennas comes from *detuning* the parasitic elements enough to raise the feed impedance to 50; /archives//html/Towertalk/2002-07/msg00386.html (9,806 bytes)
