FAQ of www.alinco.com - Tips from the manufacturer's website ALINCO

Q: Can I use coax-fed antennas like a dipole, yagi, or non-grounded vertical with the EDX-2?
A: Absolutely NOT! Please understand that the EDS-2 is a "random length long wire resonator," and the "long wire" antenna starts from the input side of the EDX-2 (feeding point), not from the output terminal. It resonates the antenna impedance automatically to the length of the wire or mobile whip you have connected to the output terminal. A grounded mobile whip such as the Out Backer works fine with the multi-band EDX-2, as long as it is fed with a single wire from the output terminal of the EDX-2 to its feeding center-point.

Q: Is the EDX-2 control-cable expandable?
A: Yes, but please use heavy-gauged wire (at least 20-18 gauge than the original cable) to avoid the loss of the driving current and it is not recommended expanding it to over 50 feet; You may find a good rotator cable as the replacement. Before unscrewing the connection inside EDX-2 for the replacement of the cable, note the color configuration of the cable / connector (There are 2 versions for the color configuration). For the input coax cable, use appropriate 50-ohm cable with PL connector.
