Readers are provided with a simple broadband antenna operating at meter wavelengths on 3...12 channels and UHF - 24 41...channels. We have in broadcasting in meter range is vertical, and decimeter - with horizontal polarization waves.
The antenna consists of two vibrators. Vibrator meter band is bent at an angle of 120°. Before him is a vibrator UHF (Fig.1).
Scan the leaf antenna is shown in Fig.2. Vibrators are bent at a 90° angle to each other. Type of antenna front shown in Fig.3, a General view - in Fig.4. Antenna vertical polarization meter and decimeter horizontal bands shown in Fig.5,6. The leaf antenna is made of any material (tube, rod, wire, bus power cable) with a diameter of 8 to 20 mm. Vibrators antenna can be manufactured separately and coupled by welding or screws. The lead-in cable is connected at points A and B. optional mounting to the mast and addition of antennas to the yoke with the Directors UHF shown in Fig.6.
