The moderator (me) has no problems with this subject. I have no deputy moderators, but will and have intervened if something gets out of hand. This is a good discussion that I find interesting. It ap
Hi Gedas, If I have read you correctly...... First, set your ground descriptions to "very poor" or "extremely poor". In reality, ground losses on 630m will be huge and unavoidable, so one might as we
Very interesting. You should note from the resonance Z of 42 ohms and the combined R in the big coils of 40 ohms that just about all the power is dissipated in the coils. This is why people have gone
At this point in the experiment, you wind it, put it on the analyzer, read it, use it. It will show the separate R and X. Measure, measure, measure and type the facts into the EZNEC loads. The more s
Hi Dave, What are you using for the vertical's counterpoise? What are you using for the the ground type? Where is your source placed? These are essential to answer your question. 73, Guy ____________
Hi Dave, Just to make sure I didn't totally wander off the reservation in replying to your original question, you asked about the ratio of segment length to conductor diameter. I HAVE heard segment f
Hi Kevin. There are a lot of "gotcha" situations in antenna modeling where the math and the method do not deliver correct results (or worse) if those gotcha's are not avoided. The reasons are in the
Hi, Kevin, When the wires converge to a close point, like a feed point, the segments close to the convergence should be equal and small. LIterally modeling two inches of connection wire at a feedpoin
Hi, Karin, You normally can run a program where it has errors with length of segments. If wires aren't meeting at segment ends, that will stop calculation. Would need the exact error messages to make
I dont have the cd, so if you could attach the .EZ file to an email and send it to me off reflector I could run it with EZNEC Pro/4 and see if it has something that requires NEC4 or perhaps requires
