Select any programme on the TV set or the measurement device for the antenna alignment. After nishing the alignment, tighten the wing screws on the mast clamp. Indication of the reception of DVB-T signals Kathrein antennas are pre-assembled for the reception of horizontally polarised signals. However, DVB-T signals are also transmitted in vertical polarisation. For DVB-T reception, turn the antenna in its longitudinal alignment to the transmitter rotated 90° counterclockwise. Observe the direction of rotation, as otherwise moisture can ingress in the connection box through the cable entry. If the antenna was properly mounted, the cable outlet points slantwise down, and the Kathrein-writing is legible horizontally-aligned (Fig. 7). If not, the Kathrein-writing is upside-down. Safety instruction: For your own safety, it is recommended that you carry out the mounting steps specified in the following on solid ground and not on the rooftop. Mounting steps: The following steps must be carried out in order to be able to mount the antenna on the mast so that vertically polarised signals can be received: 1. Unfasten the mast clamp from the axle tube by loosening the clamping screw 2. Pull off the mast clamp 3. Rotate the clamp 90° clockwise 4. Slide the mast clamp on the previous position on the axle tube 5. Then tighten the clamping screws again. 935.543/ C/ 0707/2.3e/ZWT Abb. 6: Horizontal alignment Abb. 7: Vertical alignment Technical data of the antennas Type AOP 52 AOS 32 AOS 65 AOT 65 Order Number 212347 212349 212352 212353 Channels 21...52 21...32 21...65 21...65 Gain dB 11...15 15,5...17 11...17 12...18 Reception range MHz 470...726 470...566 470...830 470...830 Full width at half maximum horiz.° 43...26 26...21 43...21 37...18 vert.° 52...32 30...23 47...23 39...19 Front-to-back-ratio dB 24...30 27...31 25...32 23...32 Mast clamp range mm O 22...60 Length mm 1380 2830 2240 2820 Wind load at 800 N/m2 N 108 203 179 192 Limiting wind load at 1100 N/m2 N 148 287 246 263 Packing unit/weight St./kg 1/2,3 1/3,8 1/3,5 1/3,7 Packing unit dimensions mm 890 x 520 x 100 1080 x 520 x 130 960 x 520 x 130 1080 x 520 x 130 Overview of the Kathrein antenna masts Type ZSD 48 ZSF 47 ZSF 48 ZSH 47 ZSH 48 ZSH 59 ZSH 622) Order Number 218380 218385 218381 218386 218394 218382 218383 Lenght L L/m 2 x 2 = 4 2 x 2,5 = 5 2 x 3 = 6 Diameter D1/D2 D1/D2/mm 40/48 40/48 40/48 40/48 40/48 48/60 48/60 Cable entry points 3 -3 -3 5 5 Quality category (steel) St 52 St 37 St 52 St 37 St 52 St 52 St 52 Wall thickness in clamping range mm 2,5 2 2,5 2 2,5 2,5 4,5 Allowable bending moment 1), 5,0 m ---320 850 1150 1950 (1150) Effective length at 800 N/m2 4,0 m -500 1040 430 960 1280 2120 (1280) 3,0 m 1170 540 1080 ---- Allowable bending moment 1), 5,0 m ---160 700 900 1700 (900) Effectice length at 800 N/m2 4,0 m -390 920 300 840 1080 1960 (1080) 3,0 m 1110 480 1000 ---- Packing unit/weight kg 1/11,4 1/11,3 1/14,2 1/13,1 1/17,8 1/20,5 1/37,5 1) The maximum allowable moment on the clam...
