1. [TowerTalk] Modeling (score: 1): Author: kq2m@mags.net (Robert Shohet); Date: Sun, 3 Feb 2002 11:20:30 -0500; Hi Guys, It seems we have two "sides" to this issue. Those who believe in the value of modeling and those who are skeptical. Among those who are "believers", some believe that they should always use; /archives//html/Towertalk/2002-02/msg00090.html (13,840 bytes)

How about that, it worked. No modeling, no guess work, no scratching m; /archives//html/Towertalk/2002-02/msg00092.html (8,684 bytes)

But it worked compared to what? and compared to the same antenna at what heights? No modeling, no guess work, You are either being funny or you don't understand how modeling works; /archives//html/Towertalk/2002-02/msg00093.html (8,778 bytes)

[TowerTalk] Modeling (score: 1): Author: k2av@contesting.com (Guy Olinger, K2AV); Date: Sun, 3 Feb 2002 20:55:46 -0500; What the model DOES predict is that the dipole has a weakness at very low arrival angles that the vertical does not. The model *AND* your comparisons tell me that stuff is likely coming in at very lo; /archives//html/Towertalk/2002-02/msg00109.html (11,452 bytes)

Thompson); Date: Mon, 4 Feb 2002 11:22:28 -0500; Please don't rely entirely on modeling when designing and installing an antenna. Remember its just a tool to see if an antenna works in theory.

You should model your complete installation, including interaction with other antennas. (One anecdote) I do, and it prevented me from putting a 10M beam above a 15M be; /archives//html/Towertalk/2002-02/msg00120.html (10,678 bytes)

Now, if we can forget about painting towers and antennas all will be well. I think that the sun shining brightly on aluminum is a glorious sight!
