Hello, here reporting my new helical antenna, in terms of the measurements I have used this web page: https://www.jcoppens.com/ant/helix/calc.en.php
These are the data that I entered in the calculator of the page:
Design frequency: 1539.87 MHz
Number of turns: 6
Turn spacing 0.19 (wavelengths)
Materials:
* Bronze square of 140 mm and thickness: 1,5 mm
* Copper wire: 3.8 mm (Thickness)
* SMA Female connector adapter
* 1 Bolt and Thin wood stick to support the spiral and Cable Plastic Zip tiesThe signal is more stable, less packages with errors and good values of SNR that although it is not constant at least maintains higher values with a fine pointing, I would like to know your comments and opinions, suggestions ..Here are some photos and screenshots.
Thanks
