WebThe frequency range, in which the collinear array antennas operate is around 30 MHz to 3GHz which belong to the VHF and UHF bands. Construction & Working of Broad-side Array According to the standard definition, “An arrangement in which the principal direction of radiation is perpendicular to the array axis and also to the plane containing ... WebThe collinear dipole antenna consists of two or more 1/2 wavelength sections separated by a 1/4 wave phasing stub in the form of a coil. Unlike the coax collinear, the dipole version requires a ground-plane to operate. Performs well and can be used for RX and TX purposes. It can be made from any common copper household electrical wire.
