04 / PERFORMANCE COMPARISON

MTTA Series: attenuation & power performance

Compare the published cable-only attenuation and average-power references for MTTA-460, MTTA-520 and MTTA-630. Each curve ends at that model's specified operating-frequency limit.

Attenuation vs frequency

Lower values indicate less cable-only RF loss per 100 metres.
