Page 3: Introduction
Field trials of the CHA F-LOOP 2.0 demonstrated that an inside magnetic loop antenna was only around one to two S-units lower, on both transmit and receive, than an outside full-size quarter wave vertical antenna. - Page 4 ALE, which is the standard for interoperable HF communications, is an automated method of finding a frequency in the OWF and establishing and maintaining a communications link.

Page 5: Parts Of The Antenna
A magnetic loop antenna radiates at all angles from horizon to zenith, making it an equally effective antenna for both local and long-distance (DX) communication. While not specifically designed for NVIS, during field testing of the CHA F-LOOP 2.0, both DX and NVIS contacts were made on the 30 meter ham band within minutes of each other. - Page 6 The Flexible Booster Loop consists of a 48 inch diameter / 146 inch length of shorted coaxial cable with UHF Plugs at both ends and is designed to increase CHA F-LOOP 2.0 TOTAL efficiency from 60 to 15 meters. Flexible Radiator Loop Connections The Flexible Radiator Loop Connections are UHF sockets (SO-239) located on the right and left sides of the Tuning Capacitor Box (a).
- Page 7 The Aluminum Base Plate is on the bottom of the Tuning Unit (a). It is used to provide a stable base for placing the CHA F-LOOP 2.0 on a flat surface, such as a table, or to mount the CHA F-LOOP 2.0 to a tripod or other antenna mount with a 3/8”...

Page 8: Standard Single Flexible Loop Assembly
Standard Single Flexible Loop Assembly The CHA F-LOOP 2.0 antenna should be installed near the radio set; either indoors or in a sheltered outside area, such as a balcony or porch. Because the magnetic component of an electromagnetic wave is maximum at the boundary between the ground and the space above, loop performance is usually best when the loop is located near the ground at a distance outside of the loop’s close-in induction field (just a loop diameter or two). -
Page 9: Double Flexible Loop Assembly
The CHA F-LOOP 2.0 Double Flexible Loop configuration allows you to use the CHA F-LOOP 2.0 on the 80 meter ham band by extending the lower frequency of the CHA F-LOOP 2.0 down to 2.8 MHz. See Plate (4) and perform the following steps. -

(just a loop diameter or two). The CHA F-LOOP 2.0 is not waterproof and must be installed in an area protected from the weather. -
Page 11: Loop Operation
Plate 6. Power Compensator. Loop Operation The CHA F-LOOP 2.0 is very easy to use. Perform the following steps whenever you change frequency. 1. The CHA F-LOOP 2.0 is bidirectional favoring adjustment and will rotate approximately the sides, see plate (7). -
Page 12: Disassembly
Like all of our products, the CHA P-LOOP 2.0 is built to be rugged, long lasting and with details in mind. The craftsmanship of the system is unique to Chameleon Antenna . The materials used in this antenna are water and rust resistant and do not require preventive maintenance, but they should be inspected for damage and cleaned with mild household cleaners after field use. -
