Diamond CP‑6SR Vertical HF Antenna – Multiband 6 to 80m, 200W PEP, Compact 4.8m


Trustpilot

The Diamond CP‑6SR is a compact, high-performance multiband vertical HF antenna designed for 6, 10, 15, 20, 40, and 80m frequencies. With a total height of just 4.8m and 1.8m radials, it offers a space-efficient solution for amateur radio operators. Rated at 200W PEP, it maintains an SWR below 1.5, adjustable via radial length for optimal tuning.

This antenna includes mast clamps (30–62mm) and a PL connector, with flexible radial installation—ideal for limited-space setups. Its DC-grounded radiator protects against static buildup and nearby lightning strikes, enhancing safety and reliability.

The upgraded “S” version features mast isolation, reducing resonance interference and simplifying radial tuning. A short cable with a choke is included to further improve performance.

For 80m operation, the standard radial targets CW DX (3490–3520 kHz) and can be tuned up to 3550 kHz. Optional radials are available for:

  • 3575–3650 kHz (upper CW, digi-modes, lower SSB)

  • 3650–3725 kHz (lower/mid SSB), included in article 11225.R

Ideal for amateur radio, DXing, and compact installations, the CP‑6SR delivers robust multiband performance with minimal footprint..
