Making a wheeled KU antenna Author: Li Yizhang In order to easily receive Satellite TV programs in the balcony, the author has produced "Wheel Cars" KU antenna. Try. It feels practical, convenient, and special friends are described below. First, the pin is 1. 4mmx25mm, a flat steel of 135mm, and 3 to 4 each of the two ends of Fig. 1, 1 hole of the flat steel positive center drill φ8.5mm, bent into "door" Bearing frame. 2. Type φ25mimm in the 205 bearing inner ring. 圊 Wood stick is shaped, the wooden stick is 50 ~ 80mm, knocks into the wooden stick in the bearing exit 3. Press the wood shaft "" door "bearing frame according to Figure 2 , Use φ4mmx25mm self-tapping bolts to be integrated. The wheel is about 70 mm. Second, the column with a handle (see Figure 4) 1. Take a length of L., φ15 ~ φ20mm galvanized iron pipe. After the red 50mm is burned, the axial saw 40 mm is jammed, and the dovetail is formed (the dovetail portion will cast in the cement base). 2. 250mm long, φ12mm, φ14mm round steel is built about 45 ° in the center, and the end of it is solder in the center of the column, so that the round steel and the column are perpendicular to each other. Third, the pouring concrete chassis {END 3) Size: 250mm × 200mm × 100mm, weigh 15kg. Requirements: On 250 mmx200mm, the M8 × 50mm dovetail stud L roots, the screw is 12mm. Then, 120 mm long, φ10mm, roll round steel, the exposed portion is 70mm (equal to the wheel height), so that the three dovetails are equipped with equal waist triangular distribution. And a 50 mm × 50 mm plastic foam placeholder is buddy at 250 mm × 200 mm. After the concrete is solidified, the foam is removed, and 50 mm × 50 mm square hole is formed in the center. Fourth, the installation wheel 1. Use a φ8mm flat washer on the chassis M8 bolt, and the M8 nut is fixed on the chassis. 2. Turning the chassis overall, three pins, put the tail tail down, 50mm × 50mm square hole into the lack of cement slurry, put the column vertically in the square hole, after the coagulation is solid, put it in Ku Pot and ku head. A "single-wheeled car" KU antenna is made (see Figure 4). 5. Use as long as you sprinkle your handle, you can move the antenna car to run in any location inside the balcony, look for the best receiving position. Because the bottom disc is about 15kg, there are two feet in the three feet to not scroll. So after the tripod, it is very stable and does not have to worry about the pot body displacement. This device is more suitable for KU antennas below 0.6m, all weight does not exceed 20kg, so moving flexible, simple and practical.
