I take care of a couple television transmitter sites and one of the companies I do work for is Maryland Public Television and although this is not my site its our flagship station WMPT in Annapolis and on top the tower is a fourteen thousand pound dual antenna that provided our analog service at one time and our HD service. With the big repack we migrated down to channel twenty one so the entire structure had to be removed and replaced with a spacer and a new channel twenty one antenna. Apparently it was about a third the price to do this by helicopter and it only required less than three hours to swap everything out although another two days was spent doing final connections and lighting.
The entire process was video taped and can be interesting to watch. Go to:

My two sites are WCCB in Salisbury that already had a broadband antenna installed years ago and WDBP in Seaford that the tower crew spent a good two weeks on getting the tower rigged and everything prepared to do a much smaller antenna. That one was only twenty feet long and fifteen hundred pounds.
