Excellent performance and easy installationThe Sigma HF-X80XP can be mounted either on the ground or in an elevated position, depending on your needs. The antenna has a maximum transmit power of 1 kW PEP, making it ideal for radio amateurs who want to operate at high powers.
How does the Sigma HF-X80XP work?
This antenna is fed with 50 Ohm coaxial cable via a SO-239 connector at the base. The integrated 4:1 UNUN transformer, housed in an IP65 waterproof housing, lowers the impedance at the feed point, resulting in more efficient operation and easy tuning with an external ATU. For users who experience static noise, the antenna can be grounded without affecting tuning.
Frequency range with external ATU:
- 80m (3.5MHz) – 1:1 SWR
- 60m (5 MHz) – 1:1 SWR
- 40m (7 MHz) – 1:1 SWR
- 30m (10 MHz) – 1:1 SWR
- 20m (14 MHz) – 1:1 SWR
- 17m (18 MHz) – 1:1 SWR
- 15m (21 MHz) – 1:1 SWR
- 12m (24 MHz) – 1:1 SWR
- 10m (28-29 MHz) – 1:1 SWR
- 6m (50 MHz) – 1:1 SWR
Recommended coaxial cables
Use a high quality 50 Ohm coaxial cable such as RG-213 or Mini-8 for optimal performance.
Please note: When using a high power amplifier it is essential to place an external ATU between the antenna and the amplifier to prevent damage.
