6.

 

Connect  one  end  of  the  Flexible  Radiator  Loop 
(b) to the left Radiator Loop Connection (f). 

7.

 

Connect  the  other  end  of  the  Flexible  Radiator 
Loop to the right Radiator Loop Connection. 

8.

 

Secure  the  top  middle  of  the  Flexible  Radiator 
Loop  to  the  top  middle  of  the  Coupling  Loop 
with one of the attached Sticky Straps. 

9.

 

Shape the Flexible  Radiator Loop into a  circular 
shape.  The Coupling Loop and Flexible Radiator 
Loop should be in the same plane. 

10.

 

Place the CHA F-LOOP 2.0 on a flat surface, such 
as  a  table  top,  or  attach  the  Aluminum  Base 
Plate  (n)  to  a  tripod  or  other  compatible 
antenna mount. 

11.

 

Connect  the  Coaxial  Cable  Feedline  (m)  to  the 
Loop Connection (l).  

12.

 

Secure the Coaxial Cable Feedline along the 
Telescoping Mast to ensure easy tuning and 
consistent low SWR. 

13.

 

Perform  an  operational  test  (see  procedure 
below). 

 
Double Flexible Loop Assembly 

The CHA F-LOOP 2.0 Double Flexible Loop configuration allows you to use the CHA F-LOOP 2.0 on the 80 meter 
ham band by extending the lower frequency of the CHA F-LOOP 2.0 down to 2.8 MHz.  See Plate (4) and perform 
the following steps. 

 

 
Plate 4.  Double Flexible Loop Antenna. 

 

1.

 

Perform  assembly  of  the  Standard  Single 
Flexible Loop configuration. 

2.

 

Disconnect one end of the Flexible Radiator 
Loop (b) 

“Loop 1”

 from one of the  Flexible 

Radiator Loop Connections (f). 

3.

 

Connect  the  free  end  of  the  Flexible 
Radiator  Loop 

“Loop  1”

  to  the  Loop 

Extension Barrel Connector (r). 

4.

 

Connect  one  end  of  the  Flexible  Radiator 
Loop  Extension  (d) 

“Loop  2”

  to  the  open 

Flexible  Radiator  Loop  Connection  from 
step 2. 

5.

 

Form  the  Flexible  Radiator  Loop  Extension 

“Loop  2”

  into  a  loop,  like  the  Flexible 

Radiator Loop 

“Loop 1”

6.

 

Attach the top of the Flexible Radiator Loop 
Extension 

“Loop  2”

  to  the  top  of  the 

Coupling  Loop  (c)  using  the  attached  sticky 
strap. 

7.

 

Connect  the  free  end  of  the  Flexible 
Radiator  Loop  Extension 

“Loop  2”

 

to  the 

open  end  of  the  Loop  Extension  Barrel 
Connector. 

8.

 

Set Band Switch (i) to the “A” position.

 

9.

 

Perform an operational test (see procedure 
below). 

Flexible Booster Loop Assembly (CHA F-LOOP 2.0 TOTAL) 

The CHA F-LOOP 2.0 TOTAL uses the Flexible Booster Loop and a larger Coupling Loop to increase efficiency in the 
60 to 15 meter ham bands.  The CHA F-LOOP 2.0 TOTAL antenna should be installed near the radio set; either 
indoors or in a sheltered outside area, such as a balcony or porch.  Because the magnetic component of an
