dts--
Have had V* since mid-november, and can remember only about 2 instances when signal was lost due to weather. The 18" dish is more susceptible to this than a larger dish would be. The bigger the dish, the more signal gathering power it has. When I purchased and installed my own D* system, I went with the larger eliptical dish, and never once had a signal loss in approx. the 2 years I had it before switching to V*. Will stay with the 18" dish for now and see how it performs over the long haul. Good luck with your install tomorrow, and happy Vooming!
