HF Traveling Wave Dipole Antenna Codan TWD215/315/525
The HF Traveling Wave Dipole Antenna is efficient for short to medium distance communications. Its radiation patterns are generally omni-directional, resulting in a consistent coverage over the frequency range. Designed in three models to cover the HF spectrum, this antenna is rated to 1kW (PEP) voice and data.
This antenna requires a substantial cleared area at ground level for installation, and is more suitable for permanent fixed site installations.
- Antenna Traveling Wave Dipole TWD215 - 2-15 MHz (1 kW PEP)
- Antenna Traveling Wave Dipole TWD315 - 3-15 MHz (1 kW PEP)
- Antenna Traveling Wave Dipole TWD525 - 5–25 MHz (1 kW PEP)
Includes: pulleys, halyards and installation hardware.
