Know before you buy
The ATU 2.0 controller automatically adjusts the antenna to achieve the best resonance for your selected frequency. You can also use the included USB keypad for manual fine-tuning if you prefer precise control over the resonance point.
Yes, the BABY loop is built with aircraft-grade aluminum and features a weather-resistant tuning motor, making it durable enough for long-term outdoor use. Its compact 39.8-inch diameter is specifically designed to withstand environmental exposure while maintaining performance.
Absolutely. Because of its compact, low-profile design, this antenna is an excellent solution for users facing HOA limitations or those with limited yard space who still want to operate on the 40 to 10-meter bands.
The antenna is rated for a maximum power handling of 1000 watts. This robust capacity allows you to operate at high power levels without compromising the integrity of the welded loop tubing or the air-variable capacitor.
The antenna is designed for outdoor use and includes the necessary mounting hardware. It utilizes a magnetic base configuration, which provides a stable foundation for the 12 kg unit while ensuring it remains properly positioned for optimal signal reception.
The magnetic loop design offers an enhanced signal-to-noise ratio, which is particularly beneficial in urban environments where electromagnetic interference is common. By acting as a high-Q tuned circuit, it effectively filters out unwanted noise while maintaining a typical VSWR of 1.3:1.
