Hello again.Some good advice here for removing the aerial from its base.Simple really but effective.After much difficulty attempting to get mine off to replace with a smaller nicer one and tugging and pulling my guts off {yes I have some before you say it} I decided to try using a 90 degree angle jemmy bar and yes it came straight out.HEYPRESTO.Just make sure to undo the aerial totally then prise between the base and upper aerial{not car paintwork}. Lots easier than any other way I tried.
