With the view to establish a quick and easy multi-band antenna for portable and camping operations a simple long wire antenna with However, the realized gain of the low-profile wideband ferrite-loaded antenna was around −5 dBi, which is lower than that of the air-core antenna (2 dBi) at high frequency range [6]. Shop now for fast shipping and easy returns! However, adding non-magnetic polymers unavoidably decreases the permeability of hexagonal ferrite composite, thus affecting antenna miniaturization and limiting bandwidth expansion. But Raymond Haigh’s antenna shows a bit more gain, the ferrite antenna is made up of 7 pieces of ferrite rods 20 cm long and 1 cm in diameter. S. L 127mm x 9. The antenna is extremely sensitive and can be built mostly Since ferrite loopstick antennas respond mostly to the magnetic component of a radio wave, maximum groundwave signal pickup is when the radio is held in the horizontal, or usual The authors present an optimised design for such an antenna for harvesting energy from medium wave broadcast transmis-sions. Coils can be moved for best performance.
