Know before you buy
The BABY loop is significantly more compact, making it ideal for balconies, attics, or small yards. Because it is a magnetic loop, it often provides a superior signal-to-noise ratio in high-interference environments, helping you pull signals out of the noise floor better than a typical wire dipole.
No, the ATU 2.0 controller automates the process. It features automatic VFO and band tracking via CAT or CI-V connections, meaning the antenna will follow your radio's frequency changes in real-time without manual intervention.
The antenna handles up to 450 watts PEP and CW when operating at frequencies up to 21 MHz. For higher frequencies between 22 and 29.8 MHz, the power handling capacity increases to 1 kW.
Yes, it is built for durability with aircraft-grade aluminum and welded loop tubing to prevent intermittent connections. However, like any precision antenna, it should be mounted securely to withstand local wind conditions.
Yes, you can still operate the antenna effectively. The ATU 2.0 controller includes a USB keypad for manual tuning, allowing you to adjust the resonance even if you aren't using direct-frequency radio integration.
The antenna is designed for high efficiency and typically maintains an SWR of 1.3:1. The automatic tuning system ensures it stays within this range across its entire 6.6 to 29.8 MHz frequency coverage.
