I'll just add my experience with OTA  analogue vs digital.  I live only 
~25 miles south of the Missoula Montana TV transmitter sites but I am 
shadowed by a mountain from direct line of sight.  I suffered the first 
few years with extremely degraded ghost ridden NTSC reception.   A year 
or so ago,  I upgraded the family TV and switched to ATSC OTA digital.   
I went from grade "C"  to grade "A" excellent crystal clear reception.   
I did find that I had to replace my exterior TV antenna with a four bay 
bat wing (four X wire antennas in front of a mesh reflector)  and UHF 
preamp which I purchased from solid signal.  The antenna has a small 
wind load and looks extremely rugged suitable for our Montana winters.   
I'd consider giving OTA another try if I were you.
