Chameleon F-LOOP3 Portable Magnetic Loop Antenna

NOTE: This is the "BASIC" version 

New and improved!  The Chamelon HF Portable Loop Antenna, version 3.0!

This antennas works from 80 to 10M and has a diameter of 3ft.

Loop antennas have been used for years in professional defense, miilitary, diplomatic and shipboard communications which require robust and reliable general converage for radio communications.  Amazing performace from an antenna that requires no ground plane for efficient operation.  For this reason these antennas are great for those radio operators hamstrung by their HOA requiring them to use small whips with little to no success.  

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 3.0 demonstrated that an indoor magnetic loop antenna was only around one to two S-units lower, on both transmit and receive, than 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.
