Lightweight, flexible, and field-ready: this 10 m RG-316 coaxial cable with BNC male connectors is ideal for portable, QRP, and travel-friendly HF setups. Low loss at HF while keeping your pack small.
Key Features
- Impedance: 50 Ω
- Length: 10 m
- Connectors: BNC male ↔ BNC male
- Outer diameter: ~2.5 mm
- Jacket: PTFE (heat & abrasion resistant)
- Construction: Silver-plated conductor and braid, ~95% coverage
HF Performance (Typical Attenuation over 10 m)
| Frequency | Band | Loss (dB / 10 m) |
|---|---|---|
| 7 MHz | 40 m | ~0.45 dB |
| 14 MHz | 20 m | ~0.70 dB |
| 28 MHz | 10 m | ~1.20 dB |
Notes: Values are typical for quality RG-316 and may vary slightly with assembly quality, temperature, and SWR.
Why Choose RG-316 for Portable Use?
- Ultra-flexible and easy to coil for field work
- Stable impedance and reliable HF performance
- Professionally crimped BNC connectors for secure, low-loss connections
📌 Pro Tip for Portable Operators
Using end-fed wire or other non-resonant antennas? Bring a ferrite core (common-mode choke) for your coax.
- Suppresses unwanted RF on the shield
- Reduces received noise and RFI
- Improves overall station efficiency and stability
Place the ferrite near the antenna feedpoint or at the radio end. If possible, pass several turns of coax through the core for higher choking impedance.
Frequently Asked Questions
Do I need a ferrite choke with end-fed or non-resonant antennas?
Yes, we strongly recommend a ferrite core (common-mode choke). It suppresses common-mode currents on the coax, cuts noise, and improves the efficiency of your portable HF station.
Where should I place the ferrite core?
Snap it around the coax near the feedpoint or close to the transceiver. Multiple passes of the coax through the same core increase choking impedance.
Is RG-316 suitable for QRP?
Absolutely. RG-316 is light and compact—perfect for QRP and portable ops—while keeping HF losses low over short runs like 10 m.
