RADIOHUB NVIS Broadband HF Antenna – 20M to 6M

Wideband HF Performance | 14–50 MHz | SWR Below 1.5:1 | No External Tuner Required

The RADIOHUB NVIS Broadband Antenna is a versatile, wideband HF antenna designed for amateur radio operators, field communication users, and radio enthusiasts who require multi-band HF coverage from a single antenna system. Covering an extensive frequency range from 14 MHz to 50 MHz, this antenna provides convenient operation across the 20M, 17M, 15M, 12M, 10M and 6M bands.

Designed with NVIS (Near Vertical Incidence Skywave) and near-field HF communication applications in mind, the RADIOHUB NVIS Broadband Antenna is an excellent solution for installations where space is limited and conventional full-size HF antennas may not be practical. Its wideband design allows operators to move between multiple frequencies without changing antennas or relying on a separate external antenna tuner.

Wide Frequency Coverage from One Antenna

One of the main advantages of the RADIOHUB NVIS Broadband Antenna is its broad frequency coverage. With an operating range of 14–50 MHz, a single antenna can cover several popular amateur radio bands.

The antenna covers:

• 20M Band
• 17M Band
• 15M Band
• 12M Band
• 10M Band
• 6M Band

This makes it a practical choice for operators who want to simplify their antenna installation while maintaining access to multiple HF and upper-HF bands.

Low SWR Across the Frequency Range

The RADIOHUB NVIS Broadband Antenna is designed to provide SWR below 1.5:1 across the specified 14–50 MHz frequency range. This wideband performance helps provide efficient operation across multiple frequencies without the constant need for antenna adjustment or retuning.

With the antenna installed correctly and according to the recommended configuration, operators can enjoy convenient multi-band operation without the complexity normally associated with narrow-band antennas.

No External Antenna Tuner Required

A major benefit of this broadband antenna design is its tuner-free operation across the specified frequency range. There is no need to continuously adjust an antenna tuner when changing between the supported bands.

This makes the system particularly convenient for operators who frequently switch between frequencies or bands during normal operation, field communication, monitoring, testing, or amateur radio activities.

Connect your radio, select the required frequency, and operate.

Designed for NVIS Communication

NVIS, or Near Vertical Incidence Skywave, is an HF propagation technique used for communication over regional distances where traditional line-of-sight VHF/UHF communication may not provide the desired coverage.

The RADIOHUB NVIS Broadband Antenna is designed with this type of near-field and near-vertical HF communication application in mind. It can be a useful antenna solution for operators who require reliable regional HF communication while working with restricted installation space.

Actual NVIS coverage and performance will depend on factors such as antenna installation height, ground conditions, frequency, radio power, propagation conditions, surrounding structures, and the overall installation environment.

Ideal for Limited-Space Installations

Not every radio operator has access to a large property or the space required for a conventional full-size HF antenna. The RADIOHUB NVIS Broadband Antenna provides a practical alternative for limited-space installations, including residential properties, compact radio stations, field locations, and temporary communication sites.

Its practical design allows operators to achieve broad frequency coverage without installing separate antennas for every supported band.

This makes it particularly attractive for:

• Home amateur radio stations
• Compact antenna installations
• Field radio stations
• Temporary communication setups
• Emergency communication applications
• Remote operating locations
• Experimental HF stations
• Multi-band amateur radio operations

Multi-Band HF Operation Made Simple

Traditional single-band antennas are normally optimized for a specific frequency range. If an operator wants to work on several bands, multiple antennas may be required.

The RADIOHUB NVIS broadband antenna takes a different approach by providing broad frequency coverage from a single antenna system. This can help reduce installation complexity, save valuable space, and make band changes much more convenient.

Whether you are operating on 20 meters for longer HF communication, moving to 17M, 15M, 12M or 10M, or exploring the 6M band, the same antenna can be used across the specified frequency range.

Why Choose the RADIOHUB NVIS Broadband Antenna?

The RADIOHUB NVIS Broadband Antenna is designed for operators who value simplicity, flexibility and wide frequency coverage. Instead of installing several separate antennas or constantly adjusting a narrow-band antenna, users can access a wide range of frequencies from one antenna system.

Its combination of 14–50 MHz coverage, low SWR and tuner-free operation makes it a practical choice for modern multi-band HF communication.

For operators working with limited installation space, the antenna offers an efficient way to expand HF operating capability without requiring a large and complicated antenna farm.

One Antenna. Multiple Bands. Simple Operation.

Enjoy 14 MHz to 50 MHz from a single RADIOHUB antenna and explore the possibilities of multi-band HF communication.
