8. GPS
The external GPS antenna supplied with the unit must be connected; ECW100
will not operate without an adequate GPS signal.
The cable length of the 50-Ω-RG-174/U cable with MCX connector is about 5 m. A
specialist must undertake any shortening of the cable, which must not be cut to less than
0.5 m. Antenna splitters must not be used. EDIATec rejects any responsibility.
The antenna should be horizontal in straight flight and have a generally
unobstructed view of the sky, including during turns. The antenna should not
have any electrically conducting surfaces (e.g. metal, carbon fibre) above or
immediately alongside. Ideally, the antenna will be located on top of the
instrument panel. Electrically conducting sheet metal under the antenna may
enhance its performance.
The antenna base contains magnets, but nevertheless requires additional attachments.
The antenna must under no circumstances interfere with correct compass operation. If
the antenna interferes with the compass, the magnets in the antenna base must be
removed with a screwdriver and the metallic foil put back.
If the aircraft is fitted with two or more GPS antennae, they should be
separated if possible by at least 25 cm; the same holds good for ECW100 radio
antennae.
