Page 3: Introduction
Introduction Thank you for purchasing and using the Chameleon Antenna Tactical Dipole 2.0 (CHA TD 2.0) antenna. The CHA TD 2.0, shown in plate (1), is a broadband High Frequency (HF) antenna specially designed for short to long range portable and man-pack HF communication, where portability and rapid deployment are essential. - Page 4 HF radio waves propagate from the transmitting horizon. They are usable, during the day and antenna to the receiving antenna using two under optimal conditions, up to around 90 methods: ground waves and sky waves. Ground miles, see table (1). waves are composed of direct waves and Frequency Distance Frequency...

Page 9: Antenna Configurations
Antenna Configurations Using the supplied components, the CHA TD 2.0 can be deployed into a number of operationally useful antenna configurations. The two primary antenna configurations described in this manual are the Terminated Inverted “V” and the Terminated Sloping Wire configurations. Note: a floating Insulator Ring is included on both Antenna Wires to enable other antenna configurations that require elevation of the Antenna Wire somewhere along the wire, such as an Inverted “L”... - Page 10 To deploy the Terminated Inverted “V” antenna, perform the following procedure.

Page 12: Terminated Sloping Wire
Terminated Sloping Wire The CHA TD 2.0 Sloping Wire antenna, see figure (2), 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 on lower frequencies, becoming more unidirectional towards the low end of the antenna as the frequency increases. - Page 13 Resistor Unit (M) to be at a height of 13. Untie the Mini-Paracord from the support around 25 feet. If a tall support is and pull the Mini-Terminating Resistor Unit unavailable, any convenient object, such as up to the desired height. a fence post or the top of a vehicle, may be 14.
