The DiSEqC switches are housed in a waterproof enclosure that can be mounted directly on the mast. The SPU 21-02 is a 2 in 1 switch for switching between 2 SAT antennas. Programs from different satellites can be received via the SAT receiver. The SPU 21-02 can also be used to combine two 5-in-1 multi-switches. The SPU 21-02 comes with a weather protection case. So it is possible to mount it on a mast or wall safely and easily.
