[Product Overview]
This high-performance 1:6 balun (balun) is designed specifically for shortwave communications. It efficiently converts a 50 ohm unbalanced input into a 300 ohm balanced output, making it an ideal bridge between shortwave transmitters/receivers and balanced antennas (such as dipoles and inverted-V antennas). It supports an ultra-wide frequency band of 1-56 MHz, stably handles 200W of high power, and maintains a low standing wave ratio (SWR), ensuring efficient signal transmission and high communication quality.
[Specification]
Transformation Ratio: 1:6
Input Impedance: 50 ohms (unbalanced)
Output Impedance: 300 ohms (balanced)
Frequency Range: 1-56 MHz (covering key shortwave communication bands)
Maximum Standing Wave Ratio (VSWR): ≤1.5 (low-loss transmission across the entire frequency band)
Rated Power: 200W (continuous carrier power)
Dimensions: 50mm diameter x Length: 130mm
Weight: 350g
Connectors: SO-239/UHF female input, two copper-nose terminals for output
[Features]
1. 200W High Power Handling
Using high-quality magnetic cores and high-temperature-resistant wire, it stably handles 200W continuous carrier power, meeting professional high-power demands.
2. Ultra-low SWR (<1.5)
Standard SWR is strictly controlled below 1.5 across all frequency bands, reducing signal reflection loss and improving communication range and clarity.
3. 1-56MHz Ultra-Wideband Coverage
Supports all shortwave bands from 160m to 6m, allowing for multi-purpose use without frequent replacement.
4. Precise Balanced Conversion
Efficiently converts 50Ω unbalanced to 300Ω balanced, suppressing common-mode interference and improving antenna radiation efficiency.
5. Convenient Installation Design
Epoxy resin mounting plate: Sturdy and easy to secure
304 stainless steel lifting ring: Suitable for hanging/auxiliary installation
Pre-installed copper nose: Directly connects to the antenna element, saving time and effort
[Application Scenarios]
Amateur shortwave radio
Shortwave broadcast transmission and reception
Emergency communication systems
Field communication and station setup
Compatible with balanced antennas such as Dipole, Inverted V, and Windom.
[Package Included]
1 x 200W Balun 1:6 Impedance Converter
