GL-DY280IIA-1 200-290 MHz 10 dBi Folded Dipole Antenna

Wideband Butterfly Array

The GL-DY280IIA-1 stands out in its family for an exceptionally wide 200-290 MHz match, a full 90 MHz of coverage, achieved through a butterfly eight-dipole configuration. It delivers 10 dBi at a 100 W rating from a compact 3.6 m structure. The butterfly element shape is what makes such broad bandwidth practical while keeping the horizontal pattern smooth and even around the azimuth.

One Antenna, Many Channels

A 90 MHz match means a single antenna can serve systems scattered anywhere from 200 to 290 MHz, including multi-tenant sites and networks whose frequency plan spans much of the band. That removes the need to source a narrowband array for each allocation and simplifies spares. The butterfly geometry also keeps the omnidirectional pattern stable, so coverage stays uniform across directions, and the design sustains continuous transmission at 100 W.

Mechanical Build

The 3.6 m array ships separated into two parts for transport and on-site assembly, with a 50 ohm UHF or N-female feed. A 60 m/s wind rating and weatherproof hardware support permanent outdoor service, and the compact height keeps wind load low for easy mounting on masts and rooftops.

Where It Fits

• Multi-channel coverage spanning 200-290 MHz
• Sites needing a single wideband array for varied systems
• Even omnidirectional coverage with minimal dead spots
• Government, telemetry and specialised band networks

Selection

Choose GL-DY280IIA-1 when wide frequency coverage and a stable pattern matter more than maximum gain. For higher gain on a narrower band, the GL-DY280IIA and GL-DY280IA configurable arrays are the alternatives. Confirm the connector and band plan when ordering.
