               Attic Antenna for 40-, 30-, 20-, 
                17-, 15-, 12 and 10 meter Band 
             | 
          
           
            |  
               The 
                antenna was installed on the attic. Antenna was matched with help 
                an Automatic ATU in 40-, 30-, 20-, 17-, 15-, 12 and 10 meter amateur 
                Bands. The Antenna worked satisfactory on the above mentioned 
                bands. 
                
              For 
                making the antenna you need length in 50- meters insulated wire 
                in diameter 2.0 mm (12- AWG). The antenna is a stub dipole with 
                dimension 33- cm between wires and length of each side 240 cm. 
                The dimension between wires is set up by empty plastic bottles 
                (5- liter water container) that are used here as a spread insulator 
                between the wires.

               So, 
                for the stub dipole there is used (240cm x 2 x 2= 960- cm) 960 
                cm of wire. Two lengths of the wire in 40- cm each are connected 
                to the Automatic ATU. Coaxial cable is going from the Automatic 
                ATU to shack with transceiver. Rest wire (near 39.6- m) is coiled 
                around a form in diameter 55- mm. Length of the winding is 80- 
                cm. 
                
              In spite 
                of the simplicity of the design the antenna allows satisfactory 
                work in the range of amateur bands.
