"That splitter" isn't going to be very good. You need a 2-2,150 MHz, but if it's rated for 5-2150 MHz, then it should work fine.brockley said:Tried with a 40-2150 mhz splitter from RS, no luck, same problem. I will try again with the non high freq. barrel connector and see if I can get those transponders to show again. I hate to ask again, but anyone else have any suggestions on how I can get this working?
