Can someone tell me what causes a shadow or double image on a TV?

My config:
                       Splitter(3.8db loss)
               |\      
 ANT >---------| >-----+-----> TV
               |/      |_____> Stereo

             30dB WB(50M-1G) LNA

I inserted an amp just after the antenna just so I could see channel
68(FOX,~795M) better. The VHF signals were all about 10 mv, UHF
75-100uv.  The UHF jumped to about 200mv w/the amp, VHF 1-5mv.

Long story short...  Everything worked fine until about a week ago when
a shadow appeared on channel 9 (~187M ).
