DESCRIPTION
Bird APM Series Plug-In Elements are precision-calibrated RF power measurement elements engineered for use with the Bird APM-16 True Average Power Meter. Unlike standard directional elements, APM elements measure true average power independent of modulation format, making them suitable for digitally modulated carriers including LTE, TETRA, DMR, and other complex waveforms.
The APM family covers a frequency range from 2 MHz to 960 MHz, depending on band selection, with available power ranges from 1 watt to 1000 watts (band dependent). Each element is factory calibrated and frequency band specific, ensuring measurement accuracy within the defined operating range.
APM elements maintain Bird’s standard 7/8" plug-in element mechanical format, allowing secure insertion into compatible Bird meter platforms while delivering repeatable, stable RF power readings across specified bands.
Frequency bands are designated by letter (H, A, B, C, D, E) and correspond to defined frequency segments within the total 2–960 MHz range.
