symmetrical antenna current indicator

Device to monitor transmitter antenna current in an open feeder line to an antenna. Amount of antenna current is indicated by five rows of LED's in ascending order. The higher the antenna current, the more rows are lighting up. A sample of the antenna current is derived by a ferrite current transformer. by choosing the correct number of secondary windings, the monitor can be scaled for antenna currents from 25W to 2 kW.

    Designed for L-band satellite reception using the designated FR-4 from PCBWay. Manufactured antenna nicely matches the simulated performance!
    Very nicely done - A++
    The board arrived within the scheduled time. The surface finish and printing were smooth. The vacuum packaging was also strong.
    Great quality. No chips or cracks, only a few visible layer waviness. This could be sanded and polished away if need be. No complaints.
    Excellent from start to finish
    Surprisingly the silkscreen was very good and defined for my tiny text. The PCB feels very nice and the milled edges are smooth and clean. The copper pour and routing are all accurate (though I used 1...
    Came out exactly as I had hoped. Very minimal layer lines are visible in some places. They could be polished if need be. If you order these in clear resin, do not select tapped threads. I’m going to h...
    I used PCBWay to create a PCB for an environmental monitoring project with an ESP32. The entire process, from uploading files to setting up production options, was straightforward and user-friendly. ...
