1-2 hours?..You must be kidding..no situation is that complicated that it takes that amount of time to determine whether there is a LOS or not..I've been with E* almost a year now and have had a couple NLOS's. I myself while walking to a customer's house check out my compass/inclinometer and see what it will take. I do what I can for the customer and for the company I work for. When I believe it might be a NLOS I usually build a test dish hook it up to my meter and walk around and try different spots either on the floor for a pole, on the roof...just about anywhere on the customers property. If I walk around with the Dish for 1-2 hours then I call it NLOS. I do this because I love to see myself as a platinum tech and the pay for it. Also, in my office any NLOS has to be verified by an FSM.
With all that said I still take my well being over giving the customer tv. I do not go on roofs that have ice on them or heavy amounts of snow. I call it in as incomplete due to weather conditions. I have also seen tech's install 3 dish's on a customer's roof in completely different spots just to get the job done. This to me seems like a little much to me.
With all that said, I know there are a set of lazy tech's out there and would call in and ask for another tech for a second opinion.
Sorry, Pal but we don't have 120 mins to build test dishes and all that other nonsense to determine LOS..Our experience and instruments tell us that. Usually within 15 mins I can tell whether or not there is any use in remaining at the home..
If I have a close call I will get on the roof if it's safe to check it out..I will leave no stone unturned if I think it'll go in..It's entirely stupid to leave a job that can be done because if it doesn't I make ZERO dollars..I will not compromise my safety for anyone..If they want satellite tv that badly they can put the thing in themselves..I didn't sign up for a 6 week stay in the hospital so some butt wad can watch WWE Slamfest...
