Solicitation for a computer antenna program
Due to discovering that my antenna model in the ARRL "crippleware version" of EZNEC has a 20~30% error I am looking for a computer software example of an inverted V. Either 4NEC2, MMANA GAL, or EZNEC models would be appreciated. For those who might like to help a old guy out, please send me a file for an inverted V by either PM or email.
FYI: emails asking for a copy of my current non-working EZNEC model will be ignored, I'm not interested in what I did wrong but how to do it right.
I posted an EZNEC file in another thread that will give you the right result and should run with the free version of EZNEC. If there was really a 20%-30% error you were doing something wrong
To save you searching, here it is again:
In the "View Antenna" window of EZNEC, move your cursor over the wires and a note box will come up telling you the length of the wires. You don't have to calculate wire lengths by hand. Do you have a transmission line in the model? That can translate the resonant frequency.
There is about 1% difference between the file you sent and my file. The main difference is you entered wire end #2 as a X dimension (24) and I entered it as a Y dimension (24.5) which rotates the antenna 90 degrees.
Thank you I'll try that, because I was about to give up on EZNEC and go back to a calculator!
