Site Selection and Preparation. 

1.

 

Select  a  site  to  deploy  the  CHA  TD  LITE 
Horizontal  Dipole  configuration,  see  figure  (3).  
A  good  site  should  have  two  trees  or  other 
supports  that  are  120  feet  apart  and  are  tall 
enough that the ends of the antenna will be at a 
height of around 25 feet.  The best site will have 
an  additional  support  for  the  center  of  the 
antenna.    If  the  right  supports  are  not  present, 
any  convenient  objects,  such  as  fence  posts  or 
the  tops  of  vehicles,  may  be  used  as  a  field 
expedient support with reduced performance.   

2.

 

If not already attached, connect a Carabiner (d) 
to  the  Wire  Connector  (k)  ends  of  the  Antenna 
Wires.

 

Connect  the  Matching  Transformer.    Refer  to  figure 
(2) for steps (3) 

 (7).  

3.

 

Connect the Carabiner from the Wire Connector 
end  of  an  Antenna  Wire  to  the  Transformer 
Eyebolt (j). 

4.

 

Connect  the  Wire  Connector  from  the  Antenna 
Wire to the Bottom Transformer Connection (i).  
Tighten the wing nut finger tight. 

5.

 

Connect the Carabiner from the Wire Connector 
end of the other Antenna Wire to the Carabiner 
from step (3). 

6.

 

Connect  the  Wire  Connector  of  the  Antenna 
Wire  to  the  Top  Transformer  Connection  (h).  
Tighten the wing nut finger tight. 

7.

 

Connect the UHF Plug from the Coaxial Cable to 
the  UHF  Socket  (g)  on  the  Matching 
Transformer. 

Extend the Antenna Wires. 

8.

 

Fully  extend  both  Antenna  Wires  in  a  straight 
line in opposite directions along the ground. 

9.

 

Using  a  throw  weight  or  some  other  method, 
loop the Paracord over the end supports. 

10.

 

Using a Bowline or similar knot, tie a long length 
(around  50  feet)  of  Paracord  to  the  Isolation 
Loops (c) at the free ends of the Antenna Wires. 

11.

 

If a center support is available, use a Bowline or 
similar knot, tie one end of  another long length 
of  Paracord  to  the  Carabiner  from  step  (5)  and 
loop it over the center support. 

Raise the antenna. 

12.

 

Raise  the  antenna  to  the  desired  height  and 
secure  the  Paracord  to  the  supports  with  a 
Round  Turn  and  two  Half  Hitches,  or  similar 
knot.   

13.

 

Perform operational test. 

 
 
Sloping Wire 

The CHA TD LITE Sloping Wire configuration, see figure (4), is a broadband short to medium range HF antenna.  It is 
designed  to  provide  acceptable  ground  wave  and  sky  wave  propagation.    This  configuration  is  predominately 
omnidirectional,  becoming  more  bidirectional  towards  both  ends  as  the  frequency  increases.    The  Sloping  Wire 
requires  one  support,  is  a  good  general-purpose  antenna,  and  is  excellent  for  hasty  deployment.    It  should  be 
mounted at a height of 25 to 40 feet for best performance.   
 

Site Selection and Preparation. 

1.

 

Select  a  site  to  deploy  the  CHA  TD  LITE  Sloping 
Wire configuration, see  figure (4). The best  site 
should have a tree or other support that would 
enable the end of the antenna to be at a height 
of  around  25  to  40  feet.    If  a  tall  support  is 
unavailable,  any  convenient  object,  such  as  a 

fence post or the top of a vehicle, may be used 
as  a  field  expedient  support  with  reduced 
performance.    

2.

 

If not already attached, connect a Carabiner (d) 
to  the  Wire  Connector  (k)  ends  of  the  Antenna 
Wires.
