CHA P-LOOP 2.0

l.

 

Picatinny Rail 

The Picatinny Rail is located on the rear of the Tuning Box (a).  It mates with the Picatinny Rail Clamp attached 
to the Telescoping Mast (d). 

m.

 

Coupling Loop Strap 

The Coupling Loop Strap is a sticky strap used to fasten the top of the Coupling Loop (c) to the Radiator Loop 
(b). 

 
n.

 

Coupling Loop Attachment 

The Coupling Loop Attachment is used to attach the Coupling Loop (c) to the top of the Telescoping Mast (d). 

o.

 

Coupling Loop Adjustment 

The Coupling Loop Adjustment is used to tighten the Coupling Loop Attachment (n).   

 
p.

 

Portable Bag 

The Portable Bag, see plate (1), is an Olive colored classic military-style messenger bag used to store and 
transport the components of the CHA P-LOOP 2.0, making it easily transportable. 
 

q.

 

Tripod 

 

The supplied Tripod 

(not shown) 

will provide good support for the antenna under normal conditions on 

improved surfaces, such as a: deck, patio, balcony, sidewalk, driveway, etc.  If used in rough field conditions, 
the Tripod must be secured to prevent the antenna from tipping over or a larger heady-duty camera tripod 
used. 
 

r.

 

Power Compensator 

 

The Power Compensator attaches to Flexible Radiator Loop Connection (f) on the left side of the Tuning Unit 
(a).  It is used to increase the power handling capability of the CHA P-Loop 2.0.  Prolonged transmission with 
an SWR above 2.0:1 can permanently damage the Power Compensator.  

Dropping or rough handling the 

Power Compensator can permanently damage it, which is not covered by the warranty. 
 

s.

 

Clamp Nut 

 

The Clamp Nut is located on the Picatinny Rail (i) clamp, which is attached to the Telescoping Mast (d).   

 

Loop Assembly 

The CHA P-LOOP 2.0 antenna is easy to assemble.   The antenna should be located near the radio set and can be 
installed either indoors or outside. The CHA P-LOOP 2.0 is weather resistant to dripping water when mounted near 
vertically.   Because the magnetic component of an electromagnetic wave is maximum at the boundary between 
the ground and the space above, loop performance is usually best when the loop is located near the ground at a 

distance outside of the loop’s close

-in induction field (just a loop diameter or two).   Do not use an antenna tuner 

or coupler with this antenna, as it may cause you to mistune the antenna.
