Thanks Dave ... ... for the 4NEC2 download link. I didn't know 4NEC2 is free. I will be pleased to download and use it. 73, Hans DJ7BA -----Urspr¨¹ngliche Nachricht----- Von: [email protected]

Excellent advice, Hans. I might comment there is an alternative to EZNEC which is more power for antenna design, analysis, and modeling and if free for the download. That be 4NEC2. Being more

Not discussing unnecessary coax cutting - that would be a possibility for one frequency - if you agree to neglect losses without knowing them. But sometimes unknown losses are not negligable. And

Test clips have no place on 450 MHz!!!! If you must, carefully trim and insert the center conductor into the center of port 01. Carefully connect with no length the braid to the backshell of port 01.

How do you connect from the NanoVNA port to a stub length with no connector on it? I would like to test and cut a length of coax for a uhf stub that will later be soldered without a connector. At 450

If you are certain of the exact physical length of your coax and its velocuty factor. You could add a length at the radio end to make it equal to a multiple of a half wavelength, which will make the

Dan, I had the same question and found this post - it may help you decide.

Yes, it can be saved. CONFIG > SAVE

Thanks Hugen! Can I save that setting?

3300 is the maximum brightness, you can try.

Hello, I just finished building 4 12 element dual-polarity LFA antennas (96 total elements) for EME. A note concerning the H4 screen: the screen is very hard to see when outdoors in the sunlight.? I

Never mind. Found it under the marker menu. Sorry for taking up the bandwidth. Ron

Forgot to mention, do this rotation removal with a stimulus from 50kHz to twice the target frequency. Once the rotation is removed you can set the stimulus to the target range of the antenna --

It may not be possible to climb up the tower for calibration. As an experiment you can try to set a NEGATIVE electrical delay (setting can be found in the DISPLAY/SCALE menu) About -3.5nS per foot of

As Nigel said, no need for complications here. Just calibrate at the end of the cable and you're fine. The only requirement for the cable is to not change its properties between calibration and
