Holland Electronics SBD SUB-Band CATV SEPERATOR/Joiner

I used this to combine over the air TV with the HPNA output of my modem, works great! No TV interference, all channels are clear. Also, data is fast. I used the trendNet HPNA adapter at the other end, no need for a second diplexer. I also used a high pass filter to prevent my HPNA signal from leaking out of my antenna.
