Trustpilot

50 Ohm Dipole Insulator Centre – Impedance-Matched Antenna Hub

This insulator is the central component in a dipole antenna system, engineered to maintain a 50 Ohm impedance balance—ideal for efficient RF signal transmission in amateur radio setups.

Key Features:

  • Impedance: 50 Ohm, matched for standard coaxial feed lines

  • Connector: Integrated SO-239 socket for PL-259 plug compatibility

  • Construction: Lightweight yet durable (approx. 50g, 92mm wide)

  • Wire Compatibility: Optimized for 50m enamelled copper wire

  • Design Elements: Includes element crimps and strain relief holes for secure wire anchoring

Applications:

  • HF/VHF/UHF dipole antennas

  • Inverted V, fan dipoles, G5RV, and doublet configurations

  • Amateur radio and field operations

  • Balanced feed systems for reduced signal loss

This insulator ensures symmetrical signal distribution across both antenna legs, helping to minimize SWR and maximize transmission efficiency. It’s available from Radioworld UK.
