ARYCKM-C-48X 4-Element VHF Yagi 108-150 MHz | Narrow-Band | Protel - Protel Antennas - Professional Antennas for Telecomunications

Q: Which applications is the ARYCKM-C-48X typically used for?

It is used in professional VHF fixed sites where a directional pattern helps coverage control and interference mitigation, including VHF monitoring, spectrum surveillance, and ground-station deployments within 108-150 MHz (including airband monitoring in 118-137 MHz).

Q: What are the key electrical specifications?

The antenna covers 108-150 MHz with 8 MHz bandwidth, up to 10.2 dBi maximum gain, 50 ohm impedance and V/H polarization. Typical beamwidths are 75 deg (H-plane) and 55 deg (E-plane). It is rated up to 700 W with N-f connector, with VSWR = -14 dB.

Q: Is it suitable for harsh outdoor environments and lightning-prone sites?

Yes. It is designed for severe climatic conditions with stainless-steel support. All metal parts are D.C. grounded to improve lightning behaviour and outdoor reliability.

Q: Which versions and accessories are available?

Ordering versions: ARYCKM-C-48XA (aluminium dipole elements) or ARYCKM-C-48XI (stainless-steel dipole and elements). Accessories include the RAD108150 PVC radome and the ZAFZ25/114C clamp for 35-114 mm masts.

Q: Is the antenna made in Italy?

Yes. The ARYCKM-C-48X is designed and entirely manufactured in Italy.

108 - 300 MHz

VHF ANTENNA
MOD. ARYCKM-C-48X

Narrow-band 4-element directional Yagi antenna engineered for the 108–150 MHz VHF band where a controlled radiation pattern is required to improve signal-to-noise ratio, reduce co-channel / adjacent-channel interference and optimise fixed professional installations.

Designed for severe climatic conditions and continuous outdoor service, the ARYCKM-C-48X features a stainless-steel mechanical support and radiating elements in aluminium or stainless steel (depending on version). All metal parts are D.C. grounded to improve lightning behaviour and long-term reliability on exposed sites.

Typical applications include VHF monitoring and spectrum surveillance, interference hunting / direction finding support, ground-station links, and airband monitoring within the 118–137 MHz portion included in the operating range.

On request, the adapter area can be protected with the RAD108150 PVC radome. The antenna is supplied with a hot-dip galvanised clamp with stainless-steel bolts for Ø 35–114 mm masts, and uses a standard N-f connector with 700 W power handling.
