## Description

The US Army Command, Control, Communications, Computer, Cyber, Intelligence, Surveillance, and Reconnaissance (C5ISR) Center is interested in identifying industry antenna technologies that can allow tactical radios the flexibility to transmit across the Electromagnetic Spectrum (EMS) for purposes of avoiding congestion and contention.

**Problem:** Tactical vehicles integrate various omni directional antenna solutions that provide both a high physical and electromagnetic signature. Tactical radios are configured to transmit at pre-programmed frequencies (presets) and are limited to these frequencies when maneuvering across the EMS.

C5ISR Center is seeking information from companies offering solutions that leverage advancement in frequency sensing capabilities to automatically up or down convert legacy radios transmit frequency across the EMS to avoid RF congestion and/or contention. A frequency sensing capability should be integrated in a multi-band Software Define Antenna (SDA) that can support various frequencies across the EMS, waveform types, and multiple radio inputs. The information from companies can be a combination of all the desired elements or a subset of the desired elements.
