Automatic Link Establishment (ALE), frequency-hopping, and spread-spectrum modes without a tuner or coupler. The CHA TD 2.0 can be deployed by the operator in the field in less than 15 minutes, using almost any available support, with no masts or guying required. -
Page 4: Parts Of The Antenna
The CHA TD 2.0 is comprised of the following components: a. Matching Transformer The Matching Transformer, see plate (2), provides impedance matching for the CHA TD 2.0. It is permanently affixed to the Center Line Winder (b). b. Center Line Winder CHA TD 2.0... - Page 5 The Center Line Winder is used to store the Paracord (n) and enables rapid deployment and recovery of the CHA TD 2.0. The Matching Transformer (a) is permanently affixed to the Center Line Winder. The Center Line Winder is also used as the center or end support for the erected antenna.
- Page 6 Paracord, 550 Paracord (not pictured) is used to suspend components of the CHA TD 2.0 at the proper height or anchor them to the ground, depending upon the antenna configuration. Additional 50 foot length of Paracord on a Line Winder are available for purchase from Chameleon Antenna .

Field Pouch The Field Pouch, see plate (1), is used to store the components of the CHA TD 2.0, enabling rapid deployment and recovery, and making the antenna portable and man-packable. p. Coaxial Cable Assembly The Coaxial Cable Assembly (not pictured, not supplied) connects to the UHF Socket (e) at one end and the Radio Set at the other. -
Page 8: Terminated Horizontal Dipole
Terminating the Horizontal Dipole makes the antenna broad-banded. The Horizontal Dipole requires at least two supports (one at each end). A center support is also recommended. The CHA TD 2.0 Terminated Horizontal Dipole should be mounted at a height of around 25 to 40 feet for good overall results. When mounted at this height, the antenna is omnidirectional at lower frequencies. -
Page 9: Terminated Inverted "V
Inverted “V” is the ease of installation; in that it requires only one support and takes less space than a horizontal dipole antenna. The CHA TD 2.0 Terminated Inverted “V” should be mounted at a height of around 25 to 40 feet for good overall results. - Page 10 Figure 2. Terminated Inverted “V” Configuration.

Service band enabling medium to long range skywave propagation for communications outside the affected region. The CHA TD 2.0 Terminated “M” should be mounted at a height of around 25 to 40 feet for good overall results. When mounted at this height, the antenna is predominantly bidirectional broadside to the antenna. -

16. Perform operational test. Terminated Sloping Wire The CHA TD 2.0 Sloping Wire configuration, see figure (5), is a broadband medium range HF antenna. It should provide acceptable ground wave and sky wave propagation. The Sloping Wire requires one support, is a good general-purpose antenna, and is excellent for hasty deployment. - Page 13 Table 3.
