Establishment (ALE), frequency-hopping, and spread-spectrum modes when used with a wide range antenna tuner or coupler. The CHA TD LITE 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. Antennas built by Chameleon Antenna are versatile, dependable, stealthy, and built to last. -

reflected from the Earth to the ionosphere again during multihop propagation for longer range communication. The most important thing for the operator to understand about HF radio wave propagation is the concept of Maximum Usable Frequency (MUF), Lowest Usable Frequency (LUF), and Optimal Working Frequency (OWF). The MUF is the frequency for which successful communications between two points is predicted on 50% of the days of in a month. - Page 5 Plate 1. Tactical Dipole LITE Components.

Plate 2 Matching Transformer, Side View (top), Bottom View (left) and Top View (right). Antenna Configurations Using the supplied components, the CHA TD LITE can be deployed into a number of configurations. Five configurations, see table (2), are described in this manual, each with unique performance characteristics. The table can assist the operator to quickly select the most appropriate antenna configuration to meet their operational requirements. -

complexity of site selection and setup. Most configuration and frequency combinations will require a wide range antenna tuner or coupler. Sloping “V” The CHA TD LITE Sloping “V” configuration, see figure (1), is a broadband medium to long range HF antenna. It provides good medium range sky wave propagation on all frequencies and long range sky wave propagation above 16 MHz. -
