(F-LOOP 2.0 shown) 

5.

 

Extend the Telescoping Mast sections so that 
the Telescoping Mast is 24 inches in length. 

6.

 

Attach the flange at the bottom of one end 
of the Rigid Radiator Loop (o) to the left Rigid 
Radiator Loop Mount (p) using the hardware 
provided.  Do not tighten. 

7.

 

Attach  the  flange  and  the  bottom  of  the 
other end of the Rigid Radiator Loop to the 
right  Rigid  Radiator  Loop  Mount  using  the 
hardware  provided.    Tighten  the  wing  nuts 
on both sides of the loop finger tight. 

8.

 

Secure the top middle of the Rigid Radiator 
Loop to the top middle of the Coupling Loop 
with one of the attached Sticky Straps.  The 
Coupling  Loop  and  Rigid  Radiator  Loop 
should be in the same plane. 

16.

 

Place  the  CHA  F-LOOP  3.0  PLUS  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  antenna  mounts  available 
from Chameleon Antenna

TM

).

 

9.

 

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

10.

 

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

17.

 

Perform an operational test 

(see section on 

Loop Operation). 

 

 
 
Power Compensator Installation 

The optional Power Compensator will increase the power handling capability of the CHA F-LOOP 3.0 BASIC 
or TOTAL to 60W intermittent duty cycle (SSB telephony) and 25W continuous duty cycle (CW, AM, FM, 
RTTY,  and  SSB-based  digital).    To  install  the  Power  Compensator,  place  the  bracket  of  the  Power 
Compensator (s) over the left Flexible Radiator Loop Connection (f) and position the canister as shown in 
Plate (7). 

 

 

              Plate 7. Power Compensator.

 

CAUTION: When using the Power Compensator, 
exceeding  the  specified  power  limits  or 
prolonged transmission with an SWR above 3.0:1 
will 

permanently 

damage 

the 

internal 

components  of  the  Power  Compensator.    Also, 
dropping  or  rough  handling  the  Power 
Compensator  will  permanently  damage  the 
internal components.  

Damage caused by these 

conditions is not covered by the warranty.
