In my basement office I had very bad to no reception from the D1 network. Was then looking for a low-cost solution, as the demand area anyway was quite small. The price of this system seemed fine. I needed the external antenna only from the basement window position and the indoor antenna somewhere in space. Everything seemed easy, but first worked nothing. I installed the system as the items were labeled (indoor antenna / Outdooerantenne, input / output on the repeater). When nothing worked, I've read through the description. Lo and behold, there the outdoor antenna was described as a "broad" antenna. Under the "broad" antenna but was indoor antenna (?). So, replace both antennas and it is still not working. Then I thought to myself, if the labeling on the antennas is already wrong, then yes, the label (input / output) on the repeater be wrong. And so it was. Here also changed the cable accordingly and already was all good. Now I have also in my office full reception, as outside the basement window.
