Hi all,


My house is about a month from being finished and I want to start buying my gear for my home run enclosure. I am looking at the ChannelPlus or Open House coax pannels. Both companies offer a bi-directional and high headroom version. Can anyone explain the differences between these?


I haven't decided yet whether to get digital cable or satellite (I don't know if I have a good enough view of the SW sky). We have Time Warner digital in teh area, and I think here in Tampa they are just starting to pass out some of the high-def boxes. I don't have a HDTV set yet, but I want to buy the right peice of equipment for the future. I assume I need the bi-directional coax pannel for the digital cable, but don't want to limit myself by not getting the high-headroom unit if this will in fact pass a better signal.


Can anyone offer any advice?


Thanks!

Aaron

I spoke with tech support at ChannelPlus (who also manufactures the OpenHouse products) on this topic a couple of weeks ago. Here's what I learned:

- You need BID (bi-directional) for digital cable / PPV / other advanced CATV applications.

- HHR is for use with over-the-air antennas when you want to avoid the possibility of having your own signal re- broadcasting over an antenna.


Unless you're sure that you'll be using an antenna & won't need bi-directional capability, they advised using the BID unit. I didn't get the sense that the HHR unit offers any performance advantages -- the benefit relates to avoidance of unitentional broadcast rather than performance.


I know that ChannelPlus tech support monitors this forum -- please correct me if I've got any of this wrong.

I didn't know you could broadcast your own signals over an antenna.


Anyway, thanks for the info. I guess I'll just go with the bi-directional unit for now. I'll probably have digital cable at the start. I would like to get an HDTV within the next year and get a OTA antenna, so hopefully the BID will do just fine.

You got it right. The FCC limits the signal strength of any locally modulated signals to 3uV max at the antenna. This is about 1/8 of a picowatt! It takes a very specialized amplifier to provide such extreme isolation at UHF frequencies.


If you will not have a modulator AND antenna, then the BID would be the preferred version.
