I just received a refurb SCH2P last night from TSS. I bought it to keep as a backup unit in case my 10-year-old main radio ever dies. Anyway, I did a little bench-testing and saw that it continually reports "antenna disconnected" with signal strengths of 0 on both satellite and terrestrial. On the front panel display both the "sat" and "ter" bargraphs are flashing which, according to the manual, means the antenna is not connected. This unit came with an outdoor antenna which uses an F connector, so I connected it using known-good (works fine for my TV) RG-6 cables. I tried connecting the antenna directly (using a single cable) as well as through the supplied splitter (using 2 cables plus a terminator, exactly as shown in the manual). I placed the new antenna outside in the same general area as my existing outdoor antenna (which gets great reception) but still got nothing. My conclusion is that either the antenna is bad or the RF circuitry in the radio is bad (or both). Would you agree? Is there anything else I can try before I initiate a warranty return on this puppy? I would have tried swapping in my known-good Sirius antenna but it uses the original push-on style connector and I don't have any adapters. Ideas, anyone?
