SMC - HF Dipoles Centre Fed Dipole Antenna

Centre Fed Dipole Antenna

Experience top-tier performance and seamless communication with our Centre Fed Dipole Antenna. Whether you require specific frequencies or prefer customisation, we offer two options: ready-made antennas or the flexibility to cut them to your desired length. With line taps and frequency charts included, on-site adjustments are a breeze.

Crafted from high-quality purpose-designed components, our antennas are engineered to thrive in the most extreme environments, ensuring reliable performance when you need it most. Ideal for short to medium-range communication, these antennas deliver exceptional results.

At a quarter wave above ground level, our Centre Fed Dipole Antennas predominantly radiate upwards, offering partial omnidirectional coverage through skywaves. Increase the height to half wave, and the radiation pattern transforms into a figure of eight, catering to different coverage requirements.

Technical Specifications:

  • Antenna Elements: Choose from 7/0.44” (7/1.118mm) or 7/0.36” (7/0.914mm) hard drawn copper magnesium strand.
  • Insulators: Carbon loaded polypropylene for optimal performance.
  • Spreaders: Antenna spreaders on FDA/1 models are made from durable fiberglass, while feed line spreaders are either porcelain or fiberglass, as appropriate.
  • Baluns: Our wide range of matching balun transformers ensures compatibility with various input impedances and powers.

Key Performance Details:

  • Bandwidth: +/- 2% of the center frequency, ensuring precise communication.
  • VSWR (Voltage Standing Wave Ratio): Better than 1.5:1, minimising signal loss.
  • Power Handling: Supports power up to 2kW, providing ample capacity for your needs.
  • Impedance: 50 Ohms, facilitating smooth signal transmission.
  • Polarization: Horizontal, ensuring efficient horizontal signal propagation.
