CHA F-LOOP 2.0 

Page 6 

 

The Flexible Radiator Loop consists of a 34 inch diameter / 102 inch length of shorted coaxial cable with UHF 
Plugs (PL-259) at both ends.   

c.

 

Coupling Loop 

The Coupling Loop is a 6 1/2 inch diameter rigid aluminum loop, which is attached to the end of the 
Telescoping Mast (g) and used in the CHA F-LOOP 2.0 standard configuration.  A larger, 8 inch diameter rigid 
aluminum loop, is used in conjunction with the Booster Flexible Loop (e) in the CHA F-LOOP 2.0 TOTAL 
antenna configuration.

Flexible Radiator Loop Extension  

The Flexible Radiator Loop Extension consists of a 102 inch length of shorted coaxial cable with UHF Plugs at 
both ends. The Flexible Radiator Loop Extension enables the CHA F-LOOP 2.0 to operate the 80 meter ham 
band. 

e.

 

Flexible Booster Loop 

The Flexible Booster Loop consists of a 48 inch diameter / 146 inch length of shorted coaxial cable with UHF 
Plugs at both ends and is designed to increase CHA F-LOOP 2.0 TOTAL efficiency from 60 to 15 meters. 

f.

 

Flexible Radiator Loop Connections 

The  Flexible  Radiator  Loop  Connections  are  UHF  sockets  (SO-239)  located  on  the  right  and  left  sides  of  the 
Tuning Capacitor Box (a).   
 

g.

 

Telescoping Mast 

The Telescoping Mast attaches the Tuning Unit (a) to the Coupling Loop (c).
