Antenna Couplers Explained | 3 Core Benefits
Antenna couplers dynamically match your radio’s impedance (typically 50Ω) to an antenna’s fluctuating impedance—preventing up to 70% power waste as heat or reflected energy. For example, a naval HF radio transmitting 1kW into a mismatched whip antenna without a coupler might radiate only 300W, losing 700W to inefficiency. Couplers like the Rohde & Schwarz QTL1810 […]
