HAAT is used extensively in radio, as it is actually much more important than power. For international coordination, it is officially measured in meters, even by the FCC in the USA. Stations that want to increase above a certain HAAT must reduce their power accordingly, based on the maximum distance their station class is allowed to cover.
Before metrification at the FCC, the procedure to figure HAAT was relatively simple: from the proposed or actual antenna site, either 12 or 16 radials were drawn, and points at 2, 4, 6, 8, and 10 miles radius along each radial were used. The entire radial graph could be rotated to achieve the best effect for the station. The average altitude of all the specified points, minus the altitude of the antenna site, was the HAAT.
Contour data with 120 radials spaced 3 degrees apart can be downloaded from the FCC Mass Media Contour webpage (http://ftp.fcc.gov/oet/info/maps/mmb/).
Height above average terrain (HAAT) is used extensively in FM radio and television, as it is actually much more important than effective radiated power (ERP) in determining the range of broadcasts (VHF and UHF in particular, as they are line of sight transmissions).

Zone III (the zone with the flattest terrain) consists of all of Florida and the areas of Alabama, Georgia, Louisiana, Mississippi, and Texas within approximately 241.4 kilometers (150 miles) of the Gulf of Mexico.
Dilli Haat is a combination food plaza and craft bazaar located in the heart of Delhi.
Dilli Haat is an upgraded version of the traditional weekly market, offering a delightful amalgam of craft, food and cultural activities.
However, while the village Haat is a mobile, flexible arrangement, at Dilli Haat, a permanent Haat, it is the craftsmen who are mobile and ever - changing thereby offering a kaleidoscopic view of the richness and diversity of Indian handicrafts and artifacts.
