The latter statement is correct, but realize the cable approach isn't guaranteed to work in all cases. Most people would rough that sort of idea up first and if it worked in their case, then they'd spend some money and make it nice....

Here's a quick update... I check outside and there is a grounding block that is grounded into a cooper pipe. Looks like the telephone is also tied into this pipe. The cooper pipe runs inside the house and into the electrical panel. So it sounds like the cable is grounded properly.

As far as solutions go - I did find a cable isolator similar to the Jensen except it is only $10 and rated up to 1000Mhz instead of 1300Mhz like the Jensen.

However I'd much prefer to try with the custom cable / adapter approach as I don't like the idea of inserting anything before the STB. The only issue the ground loop is causing is with the BFD.

So Wayne if you'd be so kind as perhaps to provide some detailed instructions I'd like to give this a try first. If that doesn't work then I'll go to the Jensen or similar isolation transformer for insertion at the STB. Thanks!
