Overview

CHAMELEON ANTENNA F-Loop 2.0 Portable HF Loop Antennas

CHAMELEON ANTENNA F-Loop 2.0 Portable HF Loop Antennas were designed with portability, ease of use, ruggedness and high performance in mind. CHA F-LOOP 2.0 antennas are made with premium materials that are precisely manufactured and assembled.

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 (especially metal objects) and oriented towards the desired direction of radiation.

Magnetic loops are 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, helping to provide some immunity from interference outside the resonant bandpass.

CHA F-LOOP 2.0 Antennas were designed with weight, portability, versatility and cost in mind and are ideal for RV/camping, hotels, apartments, condominiums, homeowner's associations, deed restrictions and CCRs (Covenants, Conditions and Restrictions), Shortwave Listening (SWL) and other applications where it is not feasible to erect a multi-band wire or vertical antenna.

Some CHAMELEON ANTENNA F-Loop 2.0 Portable HF Loop Antenna details:

* 3.5 MHz to 29.7 MHz (80 - 10 meter ham bands)
* Power handling: 10W CW or 25W SSB
* The tuning box is equipped with a mounting rail for easy assembly
* 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
* The three-section collapsible portable mast allows easy storage, fast deployment and ease of use in all condition -- 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 socket for easy tripod installation on the tuning box 3/8-24 screw
* The 12 ft. RG-58 with integrated RFI choke feed-line decouples the Faraday coupling loop from the radio; which is essential to prevent SWR fluctuation while rotating the antenna or moving the coax cable around
* Custom made tuning capacitors are equipped with a 6:1 reducer and offer a smooth and consistent tuning while providing the highest efficiency
* 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
* The base of the tuning unit is equipped with an aluminum anodized base plate. The base plate may be placed directly on a flat surface or can be mounted on a tripod (1/4-20 thread)
