[CA] SR150 antenna connection
I am trying to install a new SR-150 WX receiver to use with my Axiom MFD's. It is replaceing the old SR-100 that I used with my E120 MFD. I want to use the existing SRA-40 antenna. I have wired up the power and network connections. The weather receiver shows up on the Axiom.

My problem. The antenna wire coming to the receiver is just a piece of coax (RG-58, I think). The outer cover and shield are removed, I just have the plastic surrounding the center conductor. As near as I can determine this just plugged into the old SR-100.

There is a SMA to SMB adapter supplied with the SR-150. One end has a male pin with a nut that I assume goes into the SR-150. The other end is a female receptacle. Needless to say the female end on the cable will not mate with the female end on the adapter. Should I just strip back the antenna cable, to make it a male end, or do I need some type of adapter? I know one end is SMA and the other is SMB but I do not know which is which. Should the antenna wire shield be terminated or are we only using the center conductor?

Bottom line; how di I connect the old SRA-40 antenna wire to the new SR-150 receiver?
