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

Q: Where is the ARYCKM-C-48X typically used?

The ARYCKM-C-48X is used in professional VHF installations in the 108-150 MHz range when a high-gain directional pattern is needed for coverage control and interference mitigation, including RF signal survey/radiomonitoring and airband monitoring within 108-137 MHz when used in that sub-band.

Q: What are the key electrical specifications?

It covers 108-150 MHz with 8 MHz bandwidth, max gain 10.2 dBi, return loss >= -14 dB, VSWR <= 1.5:1, 50 ohm nominal impedance and V/H polarization. Typical beamwidths are 75 deg (H-plane) and 55 deg (E-plane). Max input power is 700 W with N-f connector.

Q: Is it suitable for harsh outdoor environments?

Yes. The antenna is designed for severe climatic conditions and continuous outdoor service. All metal parts are D.C. grounded, improving behaviour against electrostatic charges and lightning-related effects. A radome cover for the adapter can be supplied on request (no full radome).

Q: Which versions and accessories are available?

Versions: ARYCKM-C-48XA (aluminium dipole) or ARYCKM-C-48XI (stainless-steel dipole). Accessories include RAD108150 PVC radome and the ZAFZ25/114C hot-dip galvanized clamp (about 1.9 kg) for Ø 35-114 mm masts.

MOD. ARYCKM-C-48X

4-Element Directional Yagi Antenna (Narrowband) – 108–150 MHz
Designed and manufactured in Italy, with robust materials and careful mechanical construction to ensure long-term reliability.

Directional 4-element VHF Yagi engineered for professional installations in the 108–150 MHz range, where a high-gain directional pattern is required to improve link quality and to reduce unwanted signals and interference. The ARYCKM-C-48X is designed for continuous outdoor service and severe climatic conditions, making it suitable for fixed sites and critical monitoring points.

This antenna is frequently adopted where coverage shaping and interference mitigation are important, including RF signal survey / radiomonitoring, VHF spectrum monitoring, and airband monitoring within 108–137 MHz (when used in that sub-band for professional monitoring/receiving purposes).

The structure includes stainless-steel support and a radiant dipole available in aluminium or stainless steel (depending on version). The antenna is D.C. grounded (all metal parts) to improve behaviour against electrostatic charges and lightning-related effects. On request, the adapter can be protected with a radome cover.
