Kestrel Feather Antenna


Available on back-order


The Kestrel Feather Antenna (KFA) is a 2 dBi gain, multi‐band near‐field antenna that lowers the noise floor of the Signal Hound™ SDR Receiver. This enhances the Probability of Detection (POD) within spectral ranges that are common to wireless communication standards.

The KFA exhibits excellent near‐field characteristics across nearly the entire Signal Hound TM SDR Receiver operational bandwidth.

The Kestrel Feather Antenna is a passive, high gain antenna. It lowers the Ambient Noise Floor (ANF) while exposing hidden and potentially hostile signals. This gives improved performance over a less sensitive broadband sectional whip antenna.

Cellular: 802 MHz ‐ 896 MHz
GSM: 890 MHz ‐ 960 MHz
DCS: 1710 MHz ‐ 1880 MHz
PCS: 1850 MHz ‐ 1990 MHz
UMTS: 1885 MHz ‐ 2025 MHz
UMTS: 2120 MHz ‐ 2200 MHz
Wi‐Fi: 2403 MHz ‐ 2483 MHz

The Kestrel Feather Antenna (KFA) has an engineered design range of 802 MHz ‐ 2483 MHz. During TSB lab testing by the manufacturer Kestrel-TSCM, the antenna exhibited excellent near‐field TSCM characteristics between (1 MHz ‐ 3500 MHz).
