935.434/C/ 935.434/C/0108/6.8d/e Mast installation and mast calculation (Fig. 1) .. Make sure masts is in vertical position when installing it .. Only use masts or standpipes specially designed for antenna installation. Other tubes mostly do not have the necessary stability to withstand heavy wind or other climatical situations. Kathrein masts and clamps fulfi ll these requirements. For an overview of the masts provided by Kathrein, see page 8 .. The clamping range of MULTIKA antennas‘ masting clamps is 22 to 60 mm .. If the mast is to be mounted on a roof, at least 1/6 of its length must be clamped .. Make sure that the mast holders (e.g. clamps) are mounted on solid ground (wood, concrete, walls) *) On buildings higher than 20 stories, a dynamic pressure of 1100 N/m2 is to be considered. Installing several antennas on one mast Never exceed the maximum load capacity of the mast or clamps when mounting several antennas on the mast. Fig. 1 Antenna installation (Fig. 2) 1. Open up antenna elements to a 90° angle; if necessary, push as far as they will go. Tighten all elements 2. If required, assemble antenna parts together and fi x with wing screws 3. fi x the dipole with the cable connection box on the square antenna pipe using a knurled screw and a spacer 4. Open up the mast clamp and fi x the antenna onto the mast. Slightly screw the wing nuts on the mast clamp so that the antenna can be aligned to optimum reception Fig. 2 Cable connection housing (Fig. 3-4) 1. Unscrew the knurled screw on the cable connection housing and remove the cover 2. Isolate the cable 3. Open the cable connection clamp and stress-resisting clamp on the cover 4. Connect the cable and clamp in fi rmly 5. Replace cover and screw down fi rmly 6. Lay the cable according to the local conditions so that it does not fl utter in the wind and chafe (use cable clamps, insulating tape or cable ties) 7. To avoid ingress of moisture in the mast or brickwork, lay the cable (Fig. 4) Antenna alignment 1. Align the antenna for optimum reception by turning it. To do this, select a channel on the TV set or use an antenna measuring instrument 2. Tighten the wing screws on the mast clamp Fig. 3 Fig. 4 DVB-T signals can also be transmitted in vertical polarisation. In order to receive vertically polarised signals, the ZTA 11 (218010) boom is required. Together with the boom, the antenna must be mounted rotated 90° counter-clockwise in longitudinal alignment to the transmitter. The rotational direction must be observed to avoid water seeping through the cable inlet into the connection socket. When properly mounted, the cable exit is directed downwards and the Kathrein signature can be read horizontally (Fig. 6). If mounted incorrectly, the Kathrein signature will be upside-down. 450 mm Fig. 5 60 mm O max.
