I went to my friend's ranch this weekend to help out and hang out. Cell phone service there is poor to non-existent. There's a tower off in the mountains some miles away, but my phone just won't hook up strong enough to work. My friend has some kind of cell phone amplifier that works pretty well, but I decided to try out another approach. I took an old satellite TV dish, nailed it to the top of a fence post, and aimed it where I thot the tower was. Then I held my phone about where I thot the focal point of the parabolic dish would be and started moving the dish around a little this way and that way. I found a spot where I could get 1 or 2 bars of signal strength and was able to call home. So, until the wind blows it off the post or an elk rubs his antlers on it and trashes it, I think this thing is going to work pretty well.
