A two-way radio is a radio that can both transmit and receive (a transceiver), unlike a broadcast receiver which only receives content. A two-way radio (transceiver) allows the operator to have a conversation with other similar radios operating on the same radio frequency (channel). Two-way radios are available in mobile, stationary base and hand-held portable configurations. Hand-held radios are often called walkie-talkies, handie-talkies, or just hand-helds. These radios have a range of a half miles to 2 miles and use small batteries. Operators who are able to communicate with each other via a tactical radio automatically gain the benefits of the Common Bond edge and may share Bennies freely.
All the radios listed here are encrypted and require a Knowledge: Cryptology roll to listen in on the signal.
A throat microphone, also laryngophone, is a type of contact microphone that absorbs vibrations directly from the wearer’s throat by way of single or dual sensors worn against the neck. The sensors, called transducers, can pick up speech even in extremely noisy or windy environments such as on a motorcycle, or in a nightclub. Other types of microphones do not function well under these conditions because of high levels of background noise. Advanced laryngophones are able to pick up whispers, and therefore perform well in environments where one has to keep quiet while communicating with others at a distance, such as during covert military operations. Throat microphones are also very useful when helmets or respiratory protection is required. Many full-face SCBA, CABA, SAR respirator, PAPR or re-breather masks do not have a provision for a microphone inside the mask. The throat microphone can be used safely, as it is positioned outside the mask’s face seal and as such does not compromise the respiratory protection provided by the mask, nor does it violate mask approvals and certification.
The Rifleman Radio is a lightweight, rugged, handheld radio that transmits voice and data via the Soldier Radio Waveform (SRW). The AN/PRC-154 Rifleman Radio acts as its own router and is not dependent on fixed infrastructures, such as cell phone towers or line-of-sight communications. Soldiers can communicate with anyone on the network and send information up and down the chain, as well as into the network backbone provided by the Warfighter Information Network-Tactical (WIN-T). The Rifleman Radio can also be linked to the Nett Warrior, an Android-based smartphone that enables Soldiers to send messages, access mission-related applications, and track one another’s locations with Global Positioning System (GPS) technology. The digital communications also enables leaders to track Soldiers’ positions and provide protection in adversarial situations. The rifleman radio has a range of 3 to 5 miles and uses medium batteries.
The AN/PRC-155 is a two-channel manpack radio designed to provide line-of-sight (LOS) and beyond-line-of-sight (BLOS), high-bandwidth waveforms for on-the-move voice, sensor, data and position-location capabilities to dismounted troops or those in vehicles during combat. Certified by the National Security Agency to communicate classified voice and data at top secret level and below, the radio is capable of supporting all three of the army’s non-proprietary networking waveforms, including soldier radio waveform (SRW), wideband networking waveform (WNW) and the mobile user objective system (MUOS). The AN/PRC-155 uses large batteries.
The AN/PRC-155 Manpack radio is equipped with a MUOS high-power amplifier that provides the radio-signal strength needed to reach the MUOS satellites that are in geo-synchronous orbit. Using both channels, the AN/PRC-155 is the bridge that connects different radios and waveforms used by soldiers across a mission area. The AN/PRC-155 MUOS Manpack receives a call from a tactical radio on one channel, routes and retransmits the call using the second channel, sending the call to a satellite communications network, like MUOS or other tactical communications network.
The Harris RF-3080-AT001 antenna provides maximum UHF SATCOM performance from a 6.5 lb package. Its crossed Yagi antenna design in a partially assembled package allows rapid deployment and directional high gain radiation pattern. The frequency range of this antenna is 240 to 400 MHz. The entire antenna is stored in an 18.5 × 6 × 6 inch package making it easy to transport.
