Hi If you are going to get any benefit from multiple antennas, you want to space them as far apart as possible. You are better off with one antenna and a splitter than with two close spaced antennas.
The cost of mucking around on the roof is non-trivial. The world is headed to L1/L2 operation on GPS and similar systems. Invest the money in one good antenna and mount rather than multiples.
