A '''tower array''' is an arrangement of multiple [[Radio masts and towers|radio tower]]s which are [[mast radiator]]s in a [[phased array]].<ref>{{cite book |url=https://books.google.com/books?id=XePEDwAAQBAJ&pg=PA129 |title=Broadcasting Journalism |author=Jacoby Barrera |year=2019 |isbn=9781839472893 |pages=129–132 |publisher=EDTECH}}</ref> They were originally developed as ground-based tracking [[radar]]s.<ref>{{cite book |url=https://books.google.com/books?id=4LtmjGNwOPIC |title=Introduction to RF Propagation |author=John S. Seybold |year=2005 |isbn=9780471743682 |publisher=[[Wiley (publisher)|Wiley]] |page=54}}</ref> Tower arrays can consist of free-standing or guyed towers or a mix of them. Tower arrays are used to constitute a [[directional antenna]] of a [[mediumwave]] or [[longwave]] [[radio station]].<br />
<br />
The number of towers in a tower array can vary.<br />
In many arrays all towers have the same height, but there are also arrays of towers of different height.<ref>{{cite book |url=https://books.google.com/books?id=K9N1TVhf82YC&pg=PA759 |title=National Association of Broadcasters Engineering Handbook: NAB Engineering Handbook |author1=Graham A.

For directional antennas with fixed [[radiation pattern]], linear arrangements are preferred, while for switchable directional patterns (usually for daytime [[groundwave]] versus nighttime [[skywave]]), square arrangements are chosen.<ref>{{cite book |url=https://books.google.com/books?id=m5DIroWLw2EC&pg=PA411 |title=Radio-electronic Transmission Fundamentals |author=B.
