3.5MHz TO 29.7MHz (80-10M) LOOP + 36" RADIATOR

This item is currently out of stock.

The CHA F-LOOP 2.0 was designed with portability, ease of use simplicity,
ruggedness and high performance in mind. Unlike any other similar antennas on
the market, the CHA F-LOOP 2.0 is made with premium materials that are
precisely manufactured and assembled in the USA!

This is an exciting new product from Chameleon Antenna. Easily deployable HF
magnetic loop antennas, also called small transmitting loops, have been
routinely used for many years in military, diplomatic, and shipboard HF
communication links, where robust and reliable general coverage radio
communication is a necessity.

These antennas have only recently become commercially available for amateur
radio. The real practical advantage of the small loop, compared to a short
vertical whip tuned against earth or a full sized vertical antenna, is the
loop's freedom from dependence on a ground plane and earth for achieving
efficient operation; this unique characteristic has profound significance for
portable or restricted space antennas.

In comparison, the bottom of a vertically oriented loop does not need to be
more than a loop diameter above ground, making it very easy to install in a
restricted space location. There is no significant improvement in sky wave
propagation performance when a small loop is installed high; all that matters
is the loop is substantially clear of objects in the immediate area and
oriented towards the desired direction of radiation.

Field trials of the CHA F-LOOP 2.0 demonstrated that an indoor magnetic loop
antenna was only around one to two S-units lower, on both transmit and receive,
than an outdoor full size quarter wave vertical antenna. Remarkable for an
antenna that is only less than three foot in diameter and covers 3.5 MHz to
29.7 MHz (80 - 10 meter ham bands)!

The magnetic loop is different from typical antennas because it emphasizes the
magnetic part of the radio wave (H field) rather than the electric part (E
field) of the radio wave. It also has a high Q resonance of around 17 KHz on 40
meters, providing immunity from interference outside the bandpass.

The CHA F-LOOP 2.0 Antenna was designed with weight, portability, versatility
and cost in mind and is ideal for RV/camping, hotels, apartments, condominiums,
homeowner's associations, deed restrictions and CCRs (Covenants, Conditions &
Restrictions), Shortwave Listening (SWL) and other places where it is not
feasible to erect a multi-band wire or vertical antenna.We're sure you will be
amazed by the performance and agree that the CHA F-LOOP 2.0 is the most
advanced portable magnetic loop antenna available today.

The crimp PL-259 connectors that we're using with all our RG-58 are UHF-7604L
connectors from PAN-PACIFIC. They're the best and the leader in the industry.

- There is no need for soldering; therefore, installation time is reduced.
- It takes an experienced technician about 15 seconds to install a crimp-crimp
connector, thereby greatly reducing the time required to create cable
assemblies. This is very important in today's cabling market where time is of
the essence and fewer technicians are being asked to maintain more and more
equipment. Digital video, computer and network cabling is almost universally
crimped today.
- Crimped connections, done correctly, can be superior to soldered connections.
- A good crimped connection deforms the metal sufficiently past the yield
point, but not too much, so that the "spring back" keeps the connection secure,
even under thermal cycling (the coefficient of expansion of the two metals
might be different) and vibration.
- A good crimp connection is gas tight and won't wick: it is sometimes referred
to as a "cold weld".
- Like the solder method, it can be used on solid or stranded conductors, and
provides a good mechanical and electrical connection.


*3.5 MHz to 29.7 MHz (80 - 10 meter ham bands)

*Power handling: 10W CW or 25W SSB

*Proprietary solderless aluminum coupling loop. This coupling loop design can
be used with any types of coax cable feed-lines. Because of its rigidity, the
antenna tuning will remain stable, consistent and will prevent SWR fluctuations
due to usual coupling loop deformation.

*The three sections collapsible portable mast allows easy storage, fast
deployment and ease of use in all conditions. No need to play with multiple
tubular PVC sections to assemble the antenna.

*The bottom of the telescopic mast is equipped with a stainless steel 3/8-24
threaded hole for easy tripod installation on the tuning box 3/8-24 screw.

*The 12' RG-58 with integrated RFI choke feed-line decouples the coupling loop
from the radio which is essential to prevent SWR fluctuation while rotating the
antenna or moving the coax cable around.

*Our custom made capacitors which are equipped with a 6:1 reducer, offer a
smooth and consistent tuning while providing the highest efficient performance
on the market.

*The Condor Mole military bag offers easy storage, transportation and
protection for the unit.

*The unit is now equipped with a NEW larger Delrin tuning knob for smoother
tuning and operation.

*A 48" diameter BOOSTER KIT for 15M to 40M can be purchased separately.

*The base of the tuning unit is equipped with an aluminum anodized base plate.

*That base plate can be placed directly on a flat surface or can be mounted on
a tripod (14-20 thread or 3/8 through hole forCHA JAWMOUNTinstallation).

*TheCHA F-LOOP Plus 2.0comes with everything included with the CHA F-LOOP 2.0 +
36" diameter collapsible loop radiator made of two sections of 1" 6061-T6
aluminum alloys pipe + 7" diameter aluminum coupling loop.

The antenna system consists of:

1 X CHA F-LOOP 2.0 tuning box
2 X LMR-400 coax cable radiator
1 X Dual Female connector
1 X 12' with integrated RFI choke feed-line
1 X Condor Molle Military Bag
1 X Proprietary coupling loop
1 X Telescopic Mast
1 X User guide
