I'll try to post a picture later but the new NV panels are wider and thicker and have a radio box usually right behind them. They are doing one panel per sector like that here. So if a tower antenna array was previously 2, 3 or 4 panels per sector the new style will be one larger panel per sector. It appears like at some of the sites around here they are leaving the older panels on the array too but those are likely just dummy panels now.
