What customers say
The Hustler RM-20S Super Resonator is highly regarded by mobile amateur radio operators for its exceptional reliability and robust build quality. Users consistently praise its ability to handle high power transmissions, often exceeding 1kW PEP, without failure. The heavy-duty construction ensures longevity against harsh mobile conditions like vibration and wind. While initial tuning requires careful adjustment, operators confirm it holds its tune well, delivering excellent signal reports and low SWR across the 20-meter band. Its seamless integration with the standard Hustler mobile system adds to its appeal. This resonator is viewed as a dependable, high-performance workhorse that justifies the investment for dedicated mobile HF enthusiasts seeking superior power handling.
Know before you buy
The RM-20S is specifically engineered for the Hustler mobile HF antenna ecosystem. While it uses a standard thread, it is designed to work optimally with Hustler masts to ensure proper resonance and structural integrity.
Because the RM-20S is a dedicated resonator for the 20-meter band, it is designed to be resonant at that frequency. While a tuner can help fine-tune your SWR, the resonator itself provides a wide enough bandwidth to operate effectively without one if your installation is properly grounded.
Yes, the RM-20S is built to handle up to 1500 Watts of power. This makes it a robust choice for operators running high-output amplifiers in their mobile HF setups.
You can expect a bandwidth of approximately 100-150 kHz while maintaining an SWR of 2:1 or better. This provides enough flexibility to move around the 20-meter band without needing to constantly adjust your antenna length.
An open box unit is a product that has been returned or had its packaging opened, but the item itself remains in new, unused condition. It has been inspected to ensure all performance specifications are met, offering you the same functionality as a brand-new unit.
