Chameleon RXL Receive Loop

The broadband design of the RXL loop is ideal for SDR receivers, AM and shortwave broadcast listeners, a small low-noise receive-only antenna for low band DXing and anybody needing a small receive antenna.

Some of the key features of the CHA RXL are:

• Wideband design – LF / MF / HF
• Highly directional
• Balanced input preamplifier to eliminate environmental noise and ground loops
• Receives on new 2200m and 630m ham bands
• Flexible mounting and power options
• Stealthy – Navy gray loop fades into the background sky.

Receive loops are very quiet and highly directional. With the built-in preamplifier, the CHA RXL will enable clearer reception than many large horizontal wire or vertical antennas. The CHA RXL covers all frequencies between 137.5 KHz and 30.0 MHz. Become a WSPR Reporting Station on the new 2200 and 630 meter bands and join the fun!
