I really don't like these Anderson Poles. I think for small projects they are just too much work. That said I have an MFJ1106 to distribute low current 12VDC to some accessories. I need a few replacement "Anderson Pole" assemblies but cannot determine which size this MFJ1106 unit uses. Any body know? Are they the 1331s? I don't want to spend an hour on the phone waiting to ask this question--too much to do. This is a simple question but cannot seem to find the answer anywhere on the internet. The MFJ manual doesn't say what the size # is. I want to order today if possible. Thanks to all!
