bent my old electric aerial mast for the 2nd time in as many years, fitted the last couple of replacements myself whithout a problem. When it came to this one I just fitted, the top end of the mast wouldn't go all the way in, so I snipped a bit of the nylon track off to make the thing shorter and it retracted perfectly. Problem now is, when the mast extends out, the mast gets to its full length and then the motor continues to extend for a further
10 seconds or so and you can hear a noisy rattling/ buzzing coming from the motor or gears as if some of the gears are fighting with the teeth on the nylon. Any ideas or experience if this is a fixable problem e.g. sensor to tell it's fully extended or something else or just give up and get a new one?Cheers :-(
