This is a used Mfj 940b antenna tuner I bought for use on a shortwave random length long wire antenna. It worked well for that but I have now gone to a new antenna that needs no tuning on the bands I am listening.
I have never transmitted through it so I cannot vouch for that part of it. I have a copied manual for it that is included.
