Antarctica has many research stations and field stations used for scientific research. Each country has their own communications resources to maintain contact between their research stations, field stations, and home countries.

Stations and camps at higher latitudes cannot access communication satellites and will use HF radio communications to supplement polar orbiting satellites. VHF and UHF radios are used for communications closer to the stations.

High Frequency Station

South Pole Station maintains communications with McMurdo Station, and other locations, using the South Pole HF (SPHF) system.

(This information is from 2007-02-15 and may be outdated.)

Group 1: McMurdo Directional

Using a directional TCI-548 log periodic antenna, three simultaneous frequencies may be received and a single frequency may be selected for transmitting.

Group 2: Omnidirectional

Provides backup to Group 1 communications and provides omni-directional HF access to other resources.

Group 3: Switched Coverage

Provides three receivers, providing coverage to Palmer, West Antarctica, and short range (using omni-directional NVIS)

McMurdo Station (NGD)

LMR Trunking

McMurdo Station reportedly uses a LMR trunked radio system in the UHF spectrum for station operations. Frequencies and talkgroups are unknown at this time.
