Easily deployable HF magnetic loop antennas have been routinely used for many years in professional
defense, military, diplomatic, and shipboard HF communication links, where robust and reliable general
coverage radio communication is deemed mandatory. You will be amazed by the performance of this
antenna. The real practical advantage of the small loop, compared to a short vertical whip is the loop’s
freedom from dependence on a ground plane and earth for achieving efficient operation; this unique
characteristic has profound significance for small restricted space antenna operation. Field trials of the
CHA F-LOOP 3.0 demonstrated that an inside magnetic loop antenna was only around one to two S-units
lower, on both transmit and receive, than an outside full-size quarter wave vertical antenna.
CHA F-LOOP BASIC 3.0 – Standard and
extended length flexible magnetic loop antenna
covering 2.8 – 29.7 MHz (80 through 10 meter
amateur bands);
CHA F-LOOP 3.0 PLUS – Same as BASIC model,
but also includes a super high-efficiency twopiece rigid aluminum radiator loop;
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).
