Mast installation and mast calculation (Fig. 1)
Q
Make sure masts is in vertical position when installing it
Q
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 ful ll these requirements. For an
overview of the masts provided by Kathrein, see page 8
Q
The clamping range of MULTIKA antennas‘ masting clamps is
22 to 60 mm
Q
If the mast is to be mounted on a roof, at least 1/6 of its length
must be clamped
Q
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/m

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.

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 x with
wing screws
3. 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 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

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 rmly
5.
Replace cover and screw down rmly
6. Lay the cable according to the local conditions so that it does
not 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
