FAQ von www.alinco.com - Tipps von der Homepage des Herstellers 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 EDX-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 multi-band mobile whip such as the Out Backer works fine with the EDX-2, as long as it is fed with a single wire from the output terminal of the EDX-2 to its center feeding-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.
