💡 Why does a standing wave ratio below 1.5 matter for SMA male antennas in wireless data modules? This ratio keeps signal reflections low so more power reaches the intended receiver. - Vertical polarization pairs well with common receiver orientations - 50 ohm impedance matches standard transmission lines easily - Independent channel use cuts down on interference issues - Supports steady gain across drone and alarm system installs
