Model: HF-250B
Frequency Range (Reception): 2–90 MHz
Effective Transmission Range:
3.5–14 MHz: very limited efficiency (primarily for reception)
18–30 MHz: limited transmission
30–50 MHz: recommended low-power use
50–57 MHz: limited transmission
Impedance: 50 Ω
VSWR: Typically <1.5 (for reception use)
Power Handling: Up to 250 W PEP (SSB, structural rating)
Length: 713 cm
Durability: Wind survival speed up to 30 m/s
Weight: 3.2 kg
Connector: M
Designed primarily for wideband reception. Transmission efficiency is limited, especially below 14 MHz. For effective HF communication, a full-size or tunable antenna is recommended.
