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  3.0  BASIC  on  a  flat 
surface,  such  as  a  tabletop,  or  attach  the 

Aluminum  Base  Plate  (n)  to  a  heavy-duty 
camera tripod or other compatible antenna 
mount 

(see the Accessories section for a list 

of  compatible  3/8

  antenna  mounts 

available from Chameleon Antenna

TM

).

 

11.

 

Connect  the  Coaxial  Cable  (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 section on 

Loop Operation). 

 

Double Flexible Loop Assembly (CHA F-LOOP 3.0 BASIC) 

The Double Single Flexible Loop configuration uses the standard Flexible Radiator Loop, Flexible Radiator 
Loop Extension (d)  and small Coupling Loop included with the CHA F-LOOP  3.0 BASIC, CHA FLOOP  3.0 
PLUS, and CHA F-FLOOP 3.0 TOTAL.   
The CHA F-LOOP 3.0 Double Flexible Loop configuration allows you to use the CHA F-LOOP 3.0 on the 80 
meter ham band by extending the lower frequency of the CHA F-LOOP 3.0 down to 2.8 MHz.  See Plate 
(5) and perform the following steps. 

 

 
Plate 5.  Double Flexible Loop Antenna. 

(CHA F-LOOP 2.0 shown)

 

 

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.
