While these prior prefabricated cables are very cheap, but it must be remembered: the coax cable diameter approx 75% smaller than standard, so grab F connector with standard measure into space, if you want to shorten eg the cable and new F-connector will screw. Second negative criticism-point: the F-screw is attached cheap, meaning it can ever get the nut when tightening the LNB or receiver to drop (Note: here you can easily squeeze with pliers that attached to the cable end part, so that the nut can not easily solve.)
