Resistor  Unit  (M)  to  be  at  a  height  of 
around  25  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.    

3.

 

Remove  the  CHA  TD  2.0  components  from 
the Duffel Bag.

 

Disconnect Unused Terminating Resistor Unit. 

4.

 

Unwind  the  Counterpoise  Wire  (G)  from 
one of the Terminating Resistor Units.

 

5.

 

Disconnect  the  Terminal  Lug  (I)  at  the  end 
of the Counterpoise Wire from the Resistor 
Connector  (N)  of  the  Terminating  Resistor 
Unit.  

 

6.

 

Unfasten the Carabiner (J) at the end of the 
Counterpoise  Wire  from  the  Strain  Relief 
Point (P) on the Terminating Resistor Unit.

 

7.

 

Leave the Counterpoise Wire on the ground 
for now and return the Terminating Resistor 
Unit to the Duffel Bag.  

 

8.

 

Unwind  the  Antenna  Wire  (H)  from  the 
other  Terminating  Resistor  Unit,  extending 
it in the general direction of where it will be 
located when the antenna is raised.

 

9.

 

Unwind  the  Counterpoise  Wire  from  the 
Terminating Resistor Unit.  

 

Raise the Antenna 

10.

 

Use  the  Throw  Bag  (U)  to  toss  one  end  of 
the  Long  Mini-Paracord  over  a  tree  branch 
or  other  convenient  support.    Secure  the 
free  end  of  the  Long  Mini-Paracord  to  the 
support. 

11.

 

Untie  the  Throw  Bag  from  the  Long  Mini-
Paracord  and  temporarily  put  it  in  your 
pocket. 

12.

 

Tie  the  Long  Mini-Paracord  to  the 
Suspension  Point  (O)  at  one  end  of  the 
Terminating  Resistor  Unit  using  a  Bowline 
or similar knot.   

13.

 

Untie  the  Mini-Paracord  from  the  support 
and pull the Mini-Terminating Resistor Unit 
up to the desired height.  

14.

 

Secure the end of the Mini-Paracord to the 
support  using  a  Round  Turn  and  two  Half-
Hitches or similar knot. 

15.

 

Extend the Antenna Wire to its full length. 

Connect the Matching Transformer 

16.

 

Attach the  Carabiner at the  low  end of the 
Antenna Wire to the Suspension Eyebolt on 
top the Matching Transformer. 

17.

 

Tie  a  Short  Mini-Paracord  (V)  to  the 
Suspension  Eyebolt  (B)  on  top  of  the 
Matching Transformer.   

18.

 

Drive  a  Tent  Stake  (T)  into  the  ground 
around  two  feet  beyond  the  end  of  the 
Antenna Wire. 

19.

 

Using a Round Turn and two Half Hitches or 
similar  knot,  tie  the  free  end  of  the  Short 
Mini-Paracord  to  the  Tent  Stake,  such  that 
the Antenna Wire is not quite taut. 

20.

 

Connect the Terminal Lug at the end of the 
Antenna  Wire  to  the  Antenna  Connection 
(D)  on  top  of  the  Matching  Transformer 
Unit.

 

21.

 

Attach  the  Carabiner,  at  the  end  of  the 
Counterpoise  Wire  from  step  (7),  to  the 
Suspension Eyebolt on top of the Matching 
Transformer.

 

22.

 

Connect the Terminal Lug, at the end of the 
Counterpoise 

Wire 

to 

the 

Bottom 

Counterpoise Connection (E) on the bottom 
of  the  Matching  Transformer  Unit. 

The 

connections  should  look  like  those  pictured 
in plate (9). 

23.

 

Extend  the  Counterpoise  Wire  on  the 
ground to its full length along the direction 
of  the  antenna  or  in  the  direction  of 
intended  communications.   

The  end  of  the 

Counterpoise  Wire  may  be  staked  to  the 
ground using a Tent Stake, if needed.
