1. [Antennaware] Re: When is a stub not just a stub (score: 120): Author: n4zr at contesting.com (Pete Smith); Date: Mon Jun 2 17:21:09 2003; It seems to me important to distinguish two distinct issues. The first is whether, for completeness, one needs to model the shield of the coax feedlines as a separate wire. Per observations by W7EL a; /archives//html/Antennaware/2003-06/msg00002.html (9,042 bytes)
2. [Antennaware] Feeding transmission lines with a common source (score: 117): Author: n4zr at contesting.com (Pete Smith); Date: Tue May 27 16:06:40 2003; I would like to be able to model the situation where two antennas are fed through transmission lines from a common source, but am having trouble figuring out how to do that in NEC-2. I tried using a; /archives//html/Antennaware/2003-05/msg00004.html (7,297 bytes)
3. [Antennaware] Feeding transmission lines with a common source (score: 118): Author: n4zr at contesting.com (Pete Smith); Date: Tue May 27 17:35:08 2003; It did -- many thanks to Bob and Chris N4VI. 73, Pete N4ZR The World HF Contest Station Database was updated 9 May 03.

4. [Antennaware] Modeling questions (score: 119): Author: n4zr at contesting.com (Pete Smith); Date: Tue Apr 29 15:59:32 2003; Using NEC-2 to attempt a model of my entire station, with particular attention to the 80-meter K3LR array that is suspended from the tower. I have a couple of specific questions: 1. What is a reasona; /archives//html/Antennaware/2003-04/msg00012.html (7,859 bytes)
5. [Antennaware] Modeling questions (score: 119): Author: n4zr at contesting.com (Pete Smith); Date: Tue Apr 29 17:45:06 2003; Thanks, Gary. This K3LR-type array seems to be very sensitive to the load value at the base of the tower, but even more so to ground conductivity. If I vary the tower-base load from 0 to 25 ohms, ove; /archives//html/Antennaware/2003-04/msg00014.html (7,341 bytes)
6. [Antennaware] Converting I and SI sources to Voltage Sources forNEC-2 (score: 118): Author: n4zr at contesting.com (Pete Smith); Date: Mon Mar 24 16:22:49 2003; I'm a layman non-engineer who needs to be able to convert I and Split-I sources to voltage sources so that they will run properly in NEC-2. For example, a simplified 8-wire yagi model with the source; /archives//html/Antennaware/2003-03/msg00000.html (7,056 bytes)
7. [Antennaware] Model needed (score: 118): Author: n4zr at contesting.com (Pete Smith); Date: Sat Mar 29 07:43:58 2003; I am working on a new method of predicting antenna performance (new to me anyway). To test the concept, I am looking for a 20 meter yagi model (EZNEC or NEC-2) that shows approximately 14.5 dBi gain; /archives//html/Antennaware/2003-03/msg00002.html (6,323 bytes)
