DAB-ARYCKM-D-48X VHF DAB Yagi 174-240 MHz | Protel - Protel Antennas - Professional Antennas for Telecomunications

Q: Which DAB/DAB+ applications is the DAB-ARYCKM-D-48X designed for?

It is designed for professional Band III DAB/DAB+ broadcast installations in the 174-240 MHz range, including transmitter sites and coverage optimization where a directional pattern is required.

Q: Can it be used for high-power transmitters?

Yes. The antenna supports high-power operation and can be supplied with N-f (500 W) or 7/16"-f (1000 W) connector option, depending on installation requirements.

Q: How does it behave against electrostatic charges and lightning-related effects?

All metal parts are D.C. grounded, improving behaviour against electrostatic charges and increasing reliability in outdoor sites where lightning-related effects may occur.

Q: Which versions and accessories are available?

Versions: DAB-ARYCKMD48XA (aluminium dipole and elements) and DAB-ARYCKMD48XI (stainless-steel dipole and elements). Optional RAD-DAB radome. Standard mounting with ZAFZ25/114C clamp for Ø 35-114 mm masts.

DAB ANTENNA
MOD. DAB-ARYCKM-D-48X

Directional VHF DAB Yagi antenna engineered for Digital Audio Broadcasting (DAB/DAB+) in Band III 174–240 MHz. The DAB-ARYCKM-D-48X is designed for professional broadcast sites where a controlled directional pattern is required to optimize coverage, improve network planning (including SFN deployments), and help mitigate unwanted signals from off-axis directions.

Built for continuous outdoor service in severe climatic conditions, this antenna features a stainless-steel support structure and can be supplied with radiant dipole and elements in aluminium or stainless steel (according to the ordered version). All metal parts are D.C. grounded, improving behaviour against electrostatic charges and lightning-related effects on towers and masts.

The antenna covers 174–240 MHz with 20 MHz bandwidth and supports high-power operation with N-f (500 W) or 7/16"-f (1000 W) connector option. On request, the adapter area can be protected with the RAD-DAB radome, to enhance durability and long-term reliability in exposed installations.

Note: antenna designed and entirely manufactured in Italy.
