(Thank you for your interest. Due to personal matters, shipping will be after October 25th.) This is a power supply "PSD-4" for a booster, manufactured by DX Antenna Co., Ltd. It has significant sun discoloration, especially on the back. The back is about the color of image ②. I searched and found that there are quite a few listings, and they are selling for around 3,000 yen, so I will list it for 1,800 yen. For those who don't mind the appearance, please consider it.
