1. [TowerTalk] Tennadyne LPDA (score: 1): Author: karkdivd@otsego.net (Dave Karklin); Date: Thu, 9 Apr 1998 20:44:38 -0400; Dear Scott: I didn't get too many comments but Bob, WS1A, agreed with my conclusion that something appears amiss on the inter-array line impedance. He stated "... you can't design a 2-boom LPDA for a; /archives//html/Towertalk/1998-04/msg00253.html (8,337 bytes)

In fact, he specifically states that it is the correct value of 377 ohms in the product brochure. A balun is required to bri; /archives//html/Towertalk/1998-04/msg00260.html (9,921 bytes)
3. [TowerTalk] Tennadyne LPDA (score: 1): Author: rhummel@cheshire.net (Robert Hummel); Date: Fri, 10 Apr 1998 10:10:18 -0400; I think you are mistaken, Anthony. Tennadyne sells their T-10 HF log as having a 50-ohm nominal impendance suitable for direct feed with 50-ohm coax. They suggest the usual 10-turn coax balun as an R; /archives//html/Towertalk/1998-04/msg00263.html (8,702 bytes)
4. [TowerTalk] Tennadyne LPDA (score: 1): Author: karkdivd@otsego.net (Dave Karklin); Date: Sat, 11 Apr 1998 09:36:09 -0400; Thanks for the suggestion, Rick. The T-10 is not a 200 ohm feed design - but nominally 50 ohm. From my approximate measurements, Z actually varies between 25 and 125 ohms.
