I tried making spacers by drilling holes in pieces of zip ties. worked pretty well, but I ended up going up to a 10ga pair of wires for the phase lines and have had better luck keeping them straight.
I put the DBGH with no reflector in my attic aimed roughly west and ended up getting about 12 analogue channels (about 2 were clear, some were fuzzy, and most were unwatchable) and I got 2 digital stations! CH 11.1 and 36.1, both from hamilton. 11.1 came in at about 82% and 36.1 came in at about 72% strength. Can't wait to get it on the roof.
