03 / RF performance

Explore attenuation and power by frequency.

The curves connect the catalogue's published tabulated values. Each cable line stops at its own stated frequency limit.

Cable attenuation vs frequency

Typical cable-only loss at +25 °C, VSWR 1.0. Lower curves mean less attenuation at a given frequency.

Units: dB/100 m. Lines join published points for visualization only; no performance is shown beyond each model's listed limit.

Average power handling vs frequency

Source reference power values at +40 °C ambient, 100 °C inner conductor, dry air at sea level and no solar loading.

Reference kW values are not rated continuous-power guarantees for MTT production or completed connector assemblies. Consider connector ratings and temperature derating.

900 MHz quick comparison

Cable-only attenuation, dB/100 m. Lower is better.
