Transmitters operating in the 1.7–2.7 GHz range are often used where SubGHz bands are congested or affected by interference. These systems use smaller antennas and are convenient for compact repeater setups. The 1–2W power output is sufficient for stable communication over medium and long distances when directional antennas are used. Well suited for mobile ground stations.
