Have you tried substituting another antenna and cable (even just a 
short cable with the antenna indoors)?  This looks like what I'd 
expect a 3801 to do if its antenna or antenna connection were 
intermittent.  While you have it disconnected, check that the 3801 is 
putting antenna power on the coax.
