I want to be able to use the remote control associated with the Joey over a greater area.The little uhf antenna on the back of the hopper is not working well enough. What kind of connector is used by this antenna so I can make up an extension cable ? The Dish installer had a very tough time putting the antenna on - I think he might have cross-threaded it by trying to screw in an "F" connector (which it definitely is not). The threads appear to be similar to a 'mini-uhf' connector but the center pin seems to be the wrong type. Can someone point me in the right direction ?
