at this point in my life I dont have the time nor desire to build things 
but prefer to buy off the shelf.  my current antenna is a DX DTA-3500 
active antenna. the one good thing about Lo-V is I canpickup harrisburg 
on many directions. With High V I have one in allentown and one in 
lancaster and two up in scranton. The allentown is religious but has a 
good signal. Lancaster NBC is good but the antenna directivity kicks in. 
All the rest are on UHF all over the place. So if I do replace this I 
need all three bands.

The other pet peeve is how the receivers scan and store. The vizios 
allow you to do a partial search but sometimes it seems even there it 
will erase things previously saved. There's no consistency on this IMHO.
