Many repeaters are located on hilltops or on tall buildings as the higher location increases their coverage area, sometimes referred to as the radio horizon, or "footprint". Amateur radio repeaters are similar in concept to those used by public safety entities (police, fire department, etc.), businesses, government, military, and more.
Linking multiple repeaters to enable a repeater outside the communications range of the handheld or mobile device to retransmit messages violates sections 95.1733(a)(8) and 95.1749 of the Commission's rules, and potentially other rules in 47 C.F.R.

Major Modifications and Amendments that change or add frequencies, emissions, ERP, Output Power, Antenna Height, Ground Elevation, change location of Base, Fixed, Mobile or Control stations or number of Mobile units and any change to station class.
The 2-meter amateur radio band is a portion of the VHF radio spectrum that comprises frequencies stretching from 144 MHz to 148 MHz [1] in International Telecommunication Union region (ITU) Regions 2 (North and South America plus Hawaii) and 3 (Asia and Oceania) [2] [3] and from 144 MHz to 146 MHz in ITU Region 1 (Europe, Africa, and Russia).
WPOZ had a repeater in Daytona Beach, WEAZ 88.1 MHz, licensed to Holly Hill; this station was permitted in 1995 as WANX, signed on as a simulcast of WPOZ as WEAZ in 1998. The operation of WEAZ (like WLMS in Lacanto) would also interfere with the WPOZ power increase, as it operated on the first adjacent 88.1 FM channel of WPOZ.
The military station operator will announce the specific amateur-band frequency being monitored. Usually, MARS stations are located in military and government installations such as The Pentagon, [5] Fort Huachuca, Andrews Air Force Base, Nellis Air Force Base, as well as Navy bases such as NAS Whidbey Island and several Coast Guard locations.
