Dual band (7 and 14 MHz) antenna 300-Ohm feeder. The coil L includes 3 coils of wire enamel insulation is 1.5. the winding is frameless, the winding diameter of 50mm. Coil L is located near the coil circuit.

Shortwave transmitting antennas

Satipatthana like w3dzz antenna. L to 20 turns of wire PEL-1.5, the diameter of the frame 50 mm: With 60 PF. LC circuits are screens to prevent the ingress of moisture into the circuit.

Quad-band antenna (28: 14; 7; 3.5 MHz), the Data L and C are selected when establishing. Indicative data: 50-60 PF. L 5-7 turns of wire PEL-1.0 on the frame with a diameter of 50 mm.

Satipatthana antenna type VS1AA connected to the transmitter circuit through the P-loop. The antenna is made of copper wire with a diameter of 2-2,5 mm. feeder - copper wire with a diameter of 1 mm (all discussed on this page, antennas and feeders - except where applied to the cable are also made from the same wire).

Antenna type "V-star". Works on all Amateur LW bands. Angle between the rays font face="Symbolа/font-72°. the length of each beam 42,25 M. Indicative data LC filter are the same. that of the Quad-band antenna. The switching of the antenna beams is produced depending on the direction of the correspondent.

Satipatthana antenna feeder of coaxial cable with a characteristic impedance of 60-70 ohms. The wire length is at 39.60 m can be mounted on horizontal rail attached to the mast. The remaining wires connected to this wire through insulators.
