Plate 3. CHA RXL Loop and Preamplifier. 

 

Plate 4. CHA RXL Preamplifier. 

a.

 

Receive Loop.  

The Receive Loop consists of a 36-inch diameter rigid aluminum loop with a Navy gray powder 

coating. 
 

b.

 

Preamplifier Unit.  

The Preamplifier Unit houses the preamplifier assembly and is used as the mount for the 

Receive Loop and Camera Tripod Attachment.  

 

c.

 

Remote Antenna Connection.  

The Remote Antenna Connection is a BNC socket used to connect the Coaxial 

Cable from the Preamplifier Unit to the BIAS-T Unit. 

 

 

d.

 

Loop Flange.  

The Loop Flanges are  used to mechanically and electrically connect the  Receive Loop and are 

located on the sides of the Preamplifier Unit and ends of the Receive Loop.  In the Export Version of the CHA 
RXL, there is also a set of Loop Flanges at the top-center of the Receive Loop and the loop is made of two pieces.
