In our Motorhome, I use a Wally with a Pathway X2. I have had to run an RG6 coax no more than 25 feet long to get the X2 to run, and it's a bit flaky even with that. I have found information that the X2 requires 14-20 volts to run consistently. There are apparently two kinds of Wallies out, one type that outputs 12.9-13.1 volts, and another (newer type?) that outputs about 19 volts. Can I insert 19 v into the second port on the X2? Will that hurt the Wally? I'd even consider buying a new Wally, but people are reporting they're still betting the 13 volt model, with no way to specify you need the 19 v version.
