CGJ100M 1.8-50mhz Portable Automatic Antenna Tuner 1-40W USB Rechargeable with 0.91inch OLED Display
A part of the review has been auto-translated.
Got the antenna tuner on 07.Oct.2021. PL plugs cannot be screwed properly. PL plugs thread to DICK!!! Therefore no real ground connection PL-connector to the PL-socket at the antenna tuner! All my PL plugs don't get proper ground contact on the CGJ-100M. An approval process is not possible under these conditions. That's why I couldn't determine if the device was working. My transceiver Yaesu FT-817. Antenna tuner was switched on and 1 hour connected to 12v. Display ok. 12v disconnected device turned on display remains dark. How long must the built-in AKKU's be loaded. Or are there no battery's built in? The PL panel jacks will probably have the same problem on all CGJ100M devices. I'm freeing you a refund or a replacement with properly matched PL sockets. Wait for your answer. Until 12.Oct.2021 no reply received!!!
