Hi Nitin, I agree with Hans' comment at reply #3, I would add, cut back and solder both central core and screen, check both for continuity/resistance with meter, if you're 100% happy that both are good and no shorts, fill the void with epoxy putty (eg JB Weld - if you can't get it locally, mail order or I'll get you a pack and post it on at cost) and press magnet back into the plastic base. Press base onto a little piece of polythene, with a flat steel surface under it, you should find some epoxy will squeeze out. Once it's completely gone off, remove from poly and break off the epoxy that's squeezed out. If not completely flat, you can lightly sand on fine wet and dry paper. Then re-apply the sticky back plastic, or a new bit if you're feeling flush! Apply some electricians' silicone grease, or at least some Vaseline or vehicle grease to threaded part of antenna and you should have a permanently weather-proofed antenna, although the steel whip will rust quickly unless thoroughly painted. AN and W&S, any chance of supplying replacement whips without bases, preferably in stainless steel. I'd buy a couple!
