Do not fill this in! == HAAT == {{main article|Height above average terrain}} The height above average terrain for VHF and higher frequencies is extremely important when considering ERP, as the signal coverage ([[broadcast range]]) produced by a given ERP dramatically increases with antenna height. Because of this, it is possible for a station of only a few hundred watts ERP to cover more area than a station of a few thousand watts ERP, if its signal travels above obstructions on the ground.
