ARYCKM-B-37X NARROW-BAND FM Yagi Antenna 3 elements 87.5-108 MHz

Q: For which applications is the ARYCKM-B-37X typically used?

The ARYCKM-B-37X is designed for professional FM broadcast sites where a directional pattern is required in the 87.5-108 MHz band, supporting coverage shaping and interference mitigation with a compact 3-element Yagi antenna.

Q: What are the main electrical characteristics?

The antenna covers 87.5-108 MHz with 3 MHz bandwidth, up to 9.2 dBi maximum gain, 50 ohm nominal impedance and V/H polarization. Typical beamwidths are 90 deg (H-plane) and 60 deg (E-plane). Maximum input power is 700 W with N-f connector or 1.2 kW with 7/16"f connector.

Q: Which mechanical and environmental features does it have?

The ARYCKM-B-37X is designed for severe climatic conditions with stainless-steel support and compact dimensions (1800x1500x100 mm). All metal parts are D.C. grounded, improving lightning behaviour and outdoor reliability on broadcast towers and masts.

Q: Which accessories and versions are available?

Accessories include the RAD87108 radome (PVC) and the ZAFZ25/114C clamp (hot-dip galvanizing). Versions: ARYCKM-B-37XA (aluminium dipole) or ARYCKM-B-37XI (stainless-steel dipole).
