Description

EasyEDA project for easy and quick build HF Antenna power supply module for working with different active antennas. Project include schematic for Antenna power supply and PCB's with differences in power circuit (PCB with/without reverse polarity protection circuit). Version for mounting SMD components.

Current development progress:

List of changes:

Version 2.1.EE: changes of the toggle switch (SW1) on the printed circuit board, now the contacts of the case are soldered to the GND area.
Version 2.0.EE: the RF line width has been recalculated using Saturn PCB Design V7.08. At the moment, the resistance of the RF line is close to 50 Ohms.
