| Keywords: Rhombic antenna diagram.svg rhombic antenna showing how it works The rhombic antenna is a directional wire antenna used on MF and HF bands for shortwave reception The antenna consists of a wire suspended above the ground in the shape of a rhombus terminated at one end by a resistor equal the the wire's characteristic impedance about 400 to 600 ohms and at the other end connected to the feedline to the receiver The rhombic is a travelling wave antenna Each segment of the rhombus has a radiation pattern as shown grey having two lobes pointed forward at a certain angle By making the corner angle equal to twice the tilt angle the main lobes of each of the 4 sides point in the same direction and reinforce each other increasing the gain 2015-03-30 own Chetvorno other versions cc-zero Uploaded with UploadWizard Rhombic antennas | ||||
