The Radioddity HF-009 is a versatile portable HF antenna designed for operators who value performance, portability, and efficiency in field operations. Because it covers multiple HF bands, it’s ideal for portable, mobile, and QRP applications.
Built with durable materials and engineered for reliable signal transmission, it provides a strong balance between compact design and effective radiation.
Overview of the Antenna
The HF-009 is a telescopic whip antenna paired with a high-quality loading coil. This design allows operators to manually tune it to resonance across several HF bands, usually from 7 MHz to 30 MHz. The whip extends fully for maximum efficiency and collapses down for transport.
Since it uses a simple yet effective base mount, the HF-009 is often paired with portable transceivers like the Xiegu G90 or the Icom IC-705. Its light weight and compact form make it an excellent companion for field work, SOTA (Summits on the Air), or emergency communication setups.
Key Features and Their Benefits
The HF-009 offers several core features that enhance its usability and performance. Each contributes to efficient communication and quick deployment, especially in portable scenarios.
Telescopic Stainless Steel Whip
The whip section provides an adjustable length, allowing precise tuning for different HF bands. Because the length can be varied, the antenna can resonate efficiently without external tuners in many cases. It is built from corrosion-resistant stainless steel, ensuring long-term reliability even in outdoor conditions.
Adjustable Loading Coil
A critical part of the HF-009, the loading coil compensates for shortened physical length by providing electrical length to achieve resonance. Operators can adjust the coil tap to fine-tune performance. This flexibility allows you to operate efficiently across 40 through 10 meters while maintaining a manageable physical size.
Compact and Lightweight Design
The entire antenna assembly weighs very little, typically under one pound. Therefore, it’s perfect for portable operation or travel. It can fit easily in a backpack and be deployed in seconds.
Durable Mounting System
The HF-009 uses a standard 3/8″-24 thread mount, compatible with a wide range of mobile and portable mounts. It can attach to magnetic bases, tripods, or vehicle mounts. This versatility gives operators freedom to choose mounting setups that match their operating style.
Efficient QRP Performance
Because of its compact coil and efficient matching characteristics, the HF-009 performs exceptionally well for QRP (low-power) operation. It delivers effective radiated power even with 5–10 watts, making it an efficient choice for small portable rigs.
Installing the Radioddity HF-009
Installation is straightforward, but proper setup ensures optimal performance. Begin by mounting the antenna on a sturdy base such as a magnetic mount or tripod. Ensure a solid electrical ground or counterpoise connection, since it significantly improves efficiency. Next, extend the telescopic whip to its full length, and connect the coaxial feedline to your transceiver.
To tune, start by selecting your desired operating band. Adjust the coil tap position until the SWR (Standing Wave Ratio) reads near 1:1 or as low as possible. If needed, slightly adjust the whip length for fine tuning. This step ensures maximum signal transfer and minimal reflected power. Once tuned, lock the coil adjustment and whip position to maintain stability.
