The coax and control cables may be extended at your own responsibilities.

Use larger gauge cables when you extend them to minimize the signal loss.

Make same connections as the originals, and be sure to use high-quality

cables for durability especially in case of outdoor installation.

About common mode and filtering

As a character of automatic tuners, you should take countermeasures

against common mode effects. It consists of installing ferrite coils and/or

beads to the coax and controll cables of EDX-3. This also depends on such

factors as the diameter and length of cables. You may search information

by using key words like "antenna tuner common mode filter" on the internet.

Careless installation and operation will cause poor efficiency, damages to

equipment and electric shock. Damages caused by common mode current

voids warranty.
