The Opticum digital satellite system is stable and allows enough reserve for bad weather. Together with a wall bracket, 100m copper cable and satellite a few screws I have thus realized for under 90 Satellite. Yet I can not recommend the product and it would not buy me one more time. Amazon indicates that a wall mount with 50mm diameter is often bought with the satellite system. Since the mirror is made of steel, came to me even a holder with 50mm diameter in question, to keep vibration in the setup even in high winds limited. But beware: The supplied mounting clamps are only suitable for a tube up to 42mm. I bent apart them so they fit around the 50mm holder, but they were too short. In three different hardware stores no matching mounting clamps were available and I received each time just the answer that these are included in the SAT systems. Not only does a steel mirror that adjusts any 50mm-holder, a total misconstruction is - to make matters worse, this circumstance is not mentioned in the product description, so you possibly could it be considered when deciding what to buy. Even the Amazon Marketplace seller was the circumstance probably not known, because who had laid the improper wall bracket for the shipping even in the box of the mirror. After complaining I was given by the seller then still mounting clamps larger Druchmesser, but I had to modify even according to the original clips to prevent twisting of the mirror in strong winds. Although this odyssey but still had a happy ending for me, I forgive only 3 stars because it took 14 days to go with me, instead of the scheduled hour. Totally incomprehensible to me, however, why Amazon indicates that the product is often purchased with a 50 mm-holder, but all three previous reviewers have awarded 5 stars. Either the product with various mounting clamps is supplied what I but can not imagine or Notice Amazon is wrong and I was the only one who bought the wall bracket with the product, or all three previous reviews are faked. To him that as I attaches great importance to a wall mount with 50mm diameter, I recommend in any case, prefer to invest a little more money into a product with matching mounting clamps.
