I think that the purchase of F-connector has definitely paid off. The image on our TV is knotless and even in bad weather, it seems to be no weak spot. The installation is really easy if you stick to the default here. Luckily, there are on the Internet several assembly instructions, if one is not quite sure. I have with us in any case provided all the ends of the satellite cable with these F connectors and for over 10 years, they are now in use. Only now and then, the devices have changed, so that the F-connector only had to be unscrewed and re-infected. I admit these F connectors clearly the top grade. I am really pleased with these connectors. Although the F-connector to the LNB see not so very new, because they are exposed to just wind and weather, but inside there is nothing here oxidized, rusted or similar. The cable connection is even after many years still very good. Therefore, I recommend these F connectors also gladly.
For me it is always surprising that this plug holds so good, but since there is no pre-assembled cables are to connect these to the LNB or multi-switch, you have to assemble the cable to the F connector always on site. But as I have already mentioned above, this is the right tool and the right know-how not so complicated as it at first sight appears.
