Page 3: Introduction
3. CHA F-LOOP 3.0 TOTAL – Same as BASIC model, but also includes a larger 48 inch diameter booster flexible loop and coupling loop to improve performance from 4.0 - 23.1 MHz (40 through 15 meter amateur bands). -

40 – 15 meter amateur service bands. The CHA F-LOOP 3.0 doesn’t require a ground-plane and doesn’t need to be mounted up high. Do not use an antenna tuner or coupler, as it may cause you to mistune the antenna. - Page 5 Earth on the first hop (around 300 miles). NVIS propagation can be used to fill this gap. The frequency selected must be below the critical frequency, so NVIS is can normally only be CHA F-LOOP 3.0 Page 5...

(DX) communication. While not specifically designed for NVIS, during field testing of the CHA F-LOOP 3.0, both DX and NVIS contacts were made on the 30 meter ham band within minutes of each other. - Page 7 Telescoping Mast (g) and used in the CHA F-LOOP BASIC 3.0 and CHA F-LOOP 3.0 PLUS antenna configurations. A larger, 8 inch diameter rigid aluminum loop, is used in conjunction with the Booster Flexible Loop (e) in the CHA F-LOOP 3.0 TOTAL antenna configuration.
- Page 8 Aluminum Base Plate - 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 3.0 on a flat surface, such as a table, or to mount the CHA F-LOOP 3.0 to a heavy-duty camera tripod or an 3/8”...

Page 12: Rigid Radiator Loop Assembly (Cha F-Loop 3.0 Plus)
The CHA F-LOOP 3.0 PLUS uses the Rigid Radiator Loop (o) and the small Coupling Loop to improve efficiency in the 40 to 10 meter ham bands. The CHA F-LOOP 3.0 PLUS antenna should be installed near the radio set; either indoors or in a sheltered outside area, such as a balcony or porch. Because the... -
Page 13: Power Compensator Installation
Power Compensator Installation The optional Power Compensator will increase the power handling capability of the CHA F-LOOP 3.0 BASIC or TOTAL to 60W intermittent duty cycle (SSB telephony) and 25W continuous duty cycle (CW, AM, FM, RTTY, and SSB-based digital). -
Page 14: Loop Operation
Loop Operation The CHA F-LOOP 3.0 is very easy to use. Perform the following steps whenever you change frequency. 1. The CHA F-LOOP 3.0 is bidirectional Table (2) shows the more precise favoring the sides, see plate (8). frequency range for each antenna possible, point one side toward the configuration and switch setting. -
