Vai al moduloMonoband HF Mobile Antenna for the 10 MHz Band
The Comet HFB-30 is a monoband HF mobile antenna specifically designed for operation on 10 MHz (30-meter band), targeting amateur radio operators and professional users who require reliable HF communications on the move. With a length of 106 cm and a weight of just 300 g, it mounts easily on virtually any vehicle without affecting handling or road clearance.
Performance and Technical Compatibility
The antenna is matched to a 50-Ohm impedance — the universal standard for HF transceivers — allowing direct connection in most installations without the need for an external antenna tuner. The PL connector (PL-259/SO-239) ensures full compatibility with the vast majority of HF transceivers and vehicle mounting bases currently available. A maximum input power of 250 W makes it suitable for SSB, CW, and digital mode operation on the 30-meter band.

Vehicle Installation for the 30-Meter Band
The Comet HFB-30 is optimised for mobile mounting on cars, SUVs, and commercial vehicles. Its compact form factor makes it particularly well suited for installations where low profile or minimal footprint is required, without sacrificing antenna performance. The 30-meter band (10 MHz) is allocated exclusively for CW and digital modes (RTTY/PSK) under IARU band plans — an operational consideration to keep in mind during use.
Why Choose a Monoband HF Mobile Antenna
Monoband antennas such as the HFB-30 deliver higher radiation efficiency on their target frequency compared to multiband solutions, as the radiating element is optimised for a single operating point. This results in a better signal-to-noise ratio and more predictable tuning behaviour — a significant advantage for operators working mobile over long distances or under varying propagation conditions.
