Flexible Booster Loop Assembly (CHA F-LOOP 3.0 TOTAL)
The CHA F-LOOP 3.0 TOTAL uses the Flexible Booster Loop (e) and a large Coupling Loop to increase
performance in the 60 to 15 meter ham bands. The CHA F-LOOP 3.0 TOTAL 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). The CHA F-LOOP 3.0 TOTAL is
not waterproof and must be installed in an area protected from the weather. Do not use an antenna
tuner with this antenna, as it may cause you to mistune the antenna.
Perform the following steps to assemble the Flexible Booster Loop Antenna, see plates (2) and (3).
1.
Select a location to setup the CHA F-LOOP
3.0 TOTAL antenna. The location can be
indoors or in an outdoors area protected
from the weather. The location must
facilitate accessibility by the operator to the
Tuning Knob (h). The operator needs to be
able to adjust the Tuning Knob while
listening to the receiver, activating the
transmitter, and observing the SWR meter.
If used indoors, the location should also be
reasonably away from switching power
supplies, Internet routers, and other sources
of electrical and electronic interference.
2.
Remove the CHA F-LOOP 3.0 TOTAL
components from the Duffel Bag (v).
3.
Attach the Telescoping Mast (g) to the
Tuning Unit (a) by screwing the bottom of
the Telescoping Mast onto the Telescoping
Mast Stud (q), located on the top of the
Tuning Unit. Tighten snuggly, by gripping the
base of the Telescoping Mast and turning
clockwise. Do not grip the mast tubing or
use tools when tightening.
4.
Attach the large 8 inch Coupling Loop (c) to
the Coupling Loop Attachment (j), located at
the top of the Telescoping Mast, by placing
the threaded hole in the Coupling Loop
bracket over the Coupling Loop Attachment
stud and turning the Coupling Loop
Adjustment (k) knob until snug. The UHF
connector should be in front of the
Telescoping Mast and point down, as shown
in the upper-left inset of Plate (3).
5.
Fully extend the Telescoping Mast sections.
6.
Connect one end of the Flexible Booster
Loop (e) to the left Radiator Loop Connection
(f).
7.
Connect the other end of the Flexible
Booster Loop to the right Radiator Loop
Connection.
8.
Secure the top middle of the Flexible Booster
Loop to the top middle of the Coupling Loop
with one of the attached Sticky Straps.
9.
Shape the Flexible Booster Loop into a
circular shape. The Coupling Loop and
Flexible Booster Loop should be in the same
plane.
14.
Place the CHA F-LOOP 3.0 TOTAL on a flat
surface, such as a tabletop, or attach the
Aluminum Base Plate (n) to a heavy-duty
camera tripod or other compatible antenna
mount
