More on the antenna

I was fiddling around wondering how on earth I was going to build myself a notch filter to filter out or reduce the signal strength on ABC when I discovered something miraculous. If I unplug the antenna from the DVB cards, just leaving the patch lead, and plug in the attenuator I bought from Jaycar, I get perfect reception on all the channels. Thank god. No more fiddling around. I have set Mythtv to record just about everything under the sun now. I doubt I’ll watch even 1/4 of it, but that’s not the point!
I just have to work out how to get the remote working now and it will be all set.
