jer9580, the spring can easily be unwound around the cable. To remove the antenna from the cable, spread the end of the spring wire and insert the rigger cable into the spring ( this is at the end of the spring towards the rigger boom). Push the rigger cable thru the spirals of the spring until it comes out of the last coil at the rear of the spring. To reinstall, wedge the rigger cable between the straight section of wire going to the the coax cable and the first coil. Rotate the spring around the cable so thet the rigger cable feeds thru the coils until it comes out at the end. It is really easy and only takes seconds.
No need to chop into the cable to add a video connector plus less connections to fail
I have been doing it this way since cannon first came out with the unit.
