sat tv definately not hooked up to phone line.
only thing on phone line is adsl splitter to modem and home phone.
 the line in from sat dish runs along same bearer as my main power string(lights/powerpoints) but the pnone line comes in from other side of house and doesn't go near either power or sat dish lines.

cat 5 cable, now why couldn't the phone guy just say that....

I haven't tried the cat 5 cable yet (don't have any on hand) but will get to that next.

The situation now is that if I run my small(350watt) inverter then the adsl only drops for a minute or so when sat tv box is powered on and going through the search for channels. it then seems to come good.

With my larger inverter that had it's own ground connection, I emailed the place who makes them and they said I didn't need to connect a ground wire(which seems odd seeming it has a specific connector for ground on the back and the instructions that came with the inverter say to do it, anyways i have it in writing from manufacturer that its ok not to...). Before, with the ground hooked up adsl would not work at all if sat tv was on, even just with this inverter turned on but everything powered through genset or other inverter. Now, without ground it drops the adsl when sat tv is powered on then comes good after minute or two like small inverter except with the big inverter I must have the modem powered on and connected to net before sat tv is powered on. If sat tv is on first modem never gets green light for internet and dsl light alternates flashing red or green.

I'll try the cat 5 cable and report finding.

thanks for ideas/advice,

Ian...
