I got an 2000 Explorer, I set the two antennas 6ft apart .The back antenna is 4 inchs shorter then the front antenna. The coax is the same length 9913.I do have 12 ft to the amp. My SWR is 1.4 back swing to 1.2. I still get RX and TX from the back and the side but I do not know if my directivity(is that a word) is more in one direction or if I'm still omni direction and pulling close to a figure 8 pattern. I read that 10 ft of 66% VF coax is about 150 degree phase shift between the 2 antennas and you get the 4.5db gain.in phase (no shift 1.1db gain) So I am still expermenting too.
