Chameleon CHA RXL – Receive Loop Antenna


The CHA RXL is a new design of high-performance Low Frequency (LF), Medium Frequency (MF), and High Frequency (HF) receive-only loop antenna that can be permanently mounted outside on a mast or used on a camera tripod next to an RV or on an apartment balcony.

Its broadband design is ideal for Software Defined Radios (SDRs), pan adapters, hams wanting a small low-noise receive-only antenna, shortwave listeners (SWLs), AM broadcast band listeners, and anybody needing a small receive antenna. 

Receive loops are very quiet and highly directional. With the built-in preamplifier, the CHA RXL will enable clearer reception than much 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!
