Thank’s Karl,
I saw that one. I believe I would like four or five antenna ports, and I know 
MFJ has them, but they are pricey. I see others available which are cheaper, 
and wonder if these things really need to cost $239 for 5 ports. I see kits 
online for around $50. That’s about the right price range, but I wonder how 
good these are.
