The GBC 58.3287.00 is an inductive RF adaptor designed to split a single coaxial antenna input into two separate RF female outputs. Both connectors use the standard 9.5mm IEC format found on televisions, set-top boxes, and antenna amplifiers.

Built from nickel-plated brass, the adaptor provides reliable contact and corrosion resistance over its rated frequency range of 5–1000 MHz, making it compatible with terrestrial and satellite-band antenna distribution.

Key Features

• Splits one 9.5mm RF male into two 9.5mm RF female outputs
• Nickel-plated brass body for corrosion resistance and secure contact
• Frequency range: 5 MHz to 1000 MHz
• Inductive (passive) design — no power required
• Straight inline form factor for compact installations

Product Benefits

• Allows a single antenna cable to feed two devices simultaneously
• 5–1000 MHz range covers all terrestrial TV bands and most satellite IF bands
• Nickel plating reduces oxidation and maintains signal quality over time
• Compact metal body fits behind TVs and inside media cabinets without adding bulk
• No tools or cable preparation needed — push-and-twist IEC connectors
