We are all prattling on about the aerial, but the tree huggers amongst us are curiuos about the welfare of the hedge, Was it a privet or laurel. Is it badly damaged or just suffering antennitis?
I hope it makes a full recovery, oh and good luck with the mast.
Sorry to hear this H but at least bodywork is ok...
PS. I hope that you called the Police to advise them of the "accident" (driving without due care) and reported the incident to your insurance company so that they can bump up your renewal premium...
