DAB-ARYCKM-D-25X Protel NARROW-BAND VHF DAB Directional Yagi 2-Element Antenna 174-240 MHz (Made in Italy)

Q: What is the DAB-ARYCKM-D-25X used for?

DAB-ARYCKM-D-25X is a directional 2-element Yagi for DAB / DAB+ Band III (174-240 MHz), used on broadcast sites where a controlled pattern supports coverage shaping, selectivity and interference mitigation, including transmitter sites, gap fillers and monitoring stations.

Q: Which electrical specifications should I expect?

It operates in 174-240 MHz with 10 MHz bandwidth, up to 7.2 dBi max gain, 50 ohm impedance, VSWR = -14 dB. Typical beamwidths are 130 degrees (H-plane) and 70 degrees (E-plane).

Q: Which connector and power rating are available?

Depending on configuration, it can be supplied with N-f connector rated up to 500 W or with 7/16-inch female connector rated up to 1000 W.

Q: Is it suitable for harsh outdoor environments?

Yes. The antenna is built for severe climatic conditions with stainless-steel support and D.C. grounded metal parts for improved behaviour against electrostatic charges and lightning-related effects. An optional RAD-DAB radome can protect the adapter when required.
