CHA MIL EXT (whip extension). 

 The CHA MIL EXT whip extension has been designed to offer maximum 

portability  and  performance  for  those  already  using  the  portable  CHA  MIL  whip  for  man-pack  antenna 
system.    This  collapsible  antenna  extension  is  used  with  the  CHA  MIL  to  create  a  17’4”  long  portable 
antenna.  When  combined  with  any  HYBRID  series  antenna  bases  the  CHA  MIL  EXT  will  operate  at  all 
frequencies in the 1.8-54 MHz band without any adjustment with most modern external antenna tuners. 

 

Counterpoise Kit.

  The Counterpoise Kit is ideal for portable antenna deployment. The system will create 

the ground-plane needed to any vertical antennas and will also play the role of guy wires.  It contains four 
25 foot wire radials secured around plastic wire winders and four steel tent stakes. 

 

60 Foot Antenna Wire Assembly. 

 Same as supplied. One additional assembly is recommended to enable 

assembly of the Inverted “V” configuration. 

 

Tripod.

 

This  heavy  duty  antenna  tripod  can  hold  equipment  up  to  15.4  lbs.  Compact  and  light  weight, 

weighing 5.5 lbs, this 10 ft tripod will give you years of service. Made of Cold-Worked Carbon with special 
design locking system and double braced legs with an extra wide footprint for added stability. This tripod 
sets up in seconds, going from 3.25 ft when fully folded to 10 ft when completely extended. Can be used 
use with any type of antenna, indoor or outdoor. 

 

Capacity  Hat.

  The  CHA  CAP-HAT  has  been  designed  to  enhance  the  radiation  of  any screw  together  HF 

antennas. 

 

50’ Paracord and Line Winder Assembly.

  One assembly is recommended to enable installation of the 

CHA MPAS wire configurations.  

 

Coaxial Cable Assembly.

  50 feet of RG-58 with integrated RFI Choke.  Used to connect the CHA MPAS to 

the radio set.  This is a highly recommended accessory if you are not using a CHA RFI CHOKE. 

 

RF Choke Assembly.

  The CHA RFI CHOKE will prevent, greatly reduces or totally eliminates the RFI carried 

by the coax cable.  It can be installed either at the antenna feed point or right behind the antenna tuner. 
This  accessory  is  highly  recommended  if  you  are  not  using  the  Chameleon  Antenna

TM

  Coaxial  Cable 

Assembly.
