HI guys,
I'm back and want to thank you again for all you help several years ago

Quick rundown of fact.  I'm located near Chester, MT, zipcode 59522.  I ended up using the old antenna at my house (24", I thinkt hey call it a  winegard style, see pic in the link above).  I also bought a Channel Master Titan 7777.
This set up worked great for several years and then everything cut out at once.  TV said "no reception".  After trying several things, I ended up bypassing the preamp box thing on the mast, but left the powered box thing near the tv connected.  By doing this, I regained TV!
So, now I get channels:
  1)  3.1 CBS
  2)  3.2 CW
  3)  5.1  no signal
  4)  5.2  no signal
  5)  12.1  no signal
  6)  13.1 CFCN-5  (W-five)
  7)  21.1 no signal
  
I beleive I lost NBC, ABC, and PBS.  I don't watch TV much.  So, my question to you is should I buy another Titan Pre-amp?  Or something else?
I pose this question as over the last couple years, stations have been swithing to digital and I don't know what would be best again.
Also, can some one explain to me what the two components (mast mounted component and power component near TV) do?
Thanks a million and a big thanks to TigerBAngs for helping me out last time.
See ya.
