I just put in a winegaurd today at 45 miles. At first, we didn't get anything. I was doing a 3 room so we were using a multi switch. I unplugged everything and just used the antenna cable straight to the box. Worked great, all but one channel. Seems that diplexers and Multi switches were stopping the power the antenna, thus not letting it work. I had to hook up the 3x2 diplexer that came with the antenna and two tv's worked. We have to order a 3x3 winegard diplexer for it to work. I struggled for a long time with it and finally figured it out. IF ANYONE IS USING A WINEGARD, DO NOT USE A MULTI SWITCH OR DIPLEXER (Except for the one they send). From what I learned today, it doesn't seem possible unless the multi switch has power pass on it like the diplexer they send does.
