CS-13326 – Vertical HF Antenna 1 kW (1.5–30 MHz), Land Stationary Kit

CS-13326 – Vertical HF Antenna 1 kW (1.5–30 MHz), Land Stationary Kit

The CS-13326 is a high-performance vertical HF antenna designed for fixed land installations (“Land Stationary”). Covering the full 1.5–30 MHz band and supporting 1 kW PEP, it is ideal for long-range HF communication networks used by military, governmental, industrial, and civilian operators.
Thanks to its standard 50 Ω impedance, the antenna operates with most HF transceivers without requiring an external ATU.

The CS-13326 vertical HF antenna is engineered for 1 kW operation and delivers stable performance across the entire HF spectrum.
This CS-13326 vertical HF antenna offers excellent efficiency for fixed HF communication sites and demanding field environments.

The CS-13326 vertical HF antenna provides outstanding performance for professional HF communication networks.

Technical Characteristics

• Frequency range: 1.5–30 MHz (wideband)
• Power handling: 1 kW PEP
• Impedance: 50 Ω
• Installation type: Land Stationary (fixed ground installation)
• Three available lengths (L):
  • L = 24 ft (≈ 7.31 m) – 6 elements
  • L = 28 ft (≈ 8.5 m) – 7 elements
  • L = 32 ft (≈ 9.6 m) – 8 elements
• MIL-STD qualified components (wind, corrosion, humidity, vibration resistance)

MIL-STD Rugged Construction

The CS-13326 is built with reinforced mechanical components and high-quality materials capable of resisting harsh environmental conditions:

• Wind, vibration, and shock resistance according to MIL-STD-810H
• Protective coatings compliant with MIL-T-704K
• UV, corrosion, humidity, and salt-spray resistant
• Heavy-duty hardware for long-lasting performance in extreme climates

These build standards ensure excellent reliability in desert, tropical, polar, coastal, and high-altitude areas.

Performance Across 1.5–30 MHz

Thanks to its wideband vertical architecture, the CS-13326 provides:

• High efficiency across the entire HF band
• Optimal radiation angle for NVIS, regional, and long-distance HF communication
• Natural matching for 1 kW HF transmitters
• Strong low-frequency performance (1.5–5 MHz), especially with the 28 ft and 32 ft versions

Longer versions improve low-band efficiency, making them ideal for long-range and emergency communication networks.

Advantages of the CS-13326

• ✔ Full HF coverage: 1.5–30 MHz
• ✔ High-power operation: 1 kW PEP
• ✔ Vertical omnidirectional radiation
• ✔ Land Stationary Kit – easy fixed installation
• ✔ No external tuner (ATU) required
• ✔ MIL-STD construction for harsh environments
• ✔ Choice of 3 lengths depending on requirements

This flexibility makes it suitable for military, industrial, humanitarian, governmental, and professional radio systems.

Typical Applications

• Military and governmental HF networks
• Emergency and disaster-relief HF systems
• Fixed HF bases and remote communication sites
• Maritime coastal communication stations
• Industrial facilities in remote or off-grid locations
