VHF – UHF Antennas
Dipole and Yagi Antennas for Amateur Repeaters
High-performance VHF and UHF antennas for repeater stations, designed for fixed installations and suitable for single use or collinear array configurations to maximize gain.
The lineup features a wideband UHF dipole antenna in black anodized aluminum (DKB/2C), alongside a wideband VHF dipole (BKG/1) and a 3-element VHF Yagi (BKR/3). The dipoles are crafted from SurTec 650-treated aluminum, while the Yagi antennas are built from stainless steel; all models incorporate PTFE insulators and stainless steel hardware. For ultimate safety, all metallic components are DC-grounded to protect against lightning strikes.
Engineered for heavy-duty operational life, these antennas are extremely rugged and fully weatherproof. Part number DKB/2C-4. specifies our 4-dipole UHF antenna system, complete with phasing harnesses and a power divider, delivering a total gain of 8 dBd.
