Hi,
I'm a novice and been searching for articles in this group for ways to isolate a homeplug network for external interference (other networks, harmonics, etc.) coming from other appartments, so my internal network becomes clean and I could use several OvisLink HP-1000U in my house at full bandwidth possible (with 10mbps I'm OK).
I'm planning to put a low-pass filter (think anything under 100Khz should work since I want to attenuate 1Mhz freqs and superiors) just BEFORE the power distribution box. A filter like a butterworth pi (2 capacitors in parallel with 1 or 2 series inductors in between) should work...
I've seen commercial ones very expensives -for what they do- (US$ 60) at Leviton's, and they only bear 20 A!!! They'd die at the first short circuit... maybe leaving the inductors in open-circuit (!)
My questions are:
1) Does exists a non-intrusive low-pass filter? I mean one that doesn't need to open wires, just put it around the line2) Is possible to build or buy one who bears more decent amps in case of a short circuit?
3) I don't know the right name for these... How should I search for that type of items in the web? low pass filter gives me very ambiguous result...Many thanx, Cro
