I have a 6000 connected to a DISH 500 with the twin LNB (built-in sw21s) and to a separate dish for the HD feed. Today I use a SW21 to combine the twin LNB and 61.5 dish together and every thing works great. My receiver sees all three birds.


I want to install and attic antenna this weekend for OTA but I don't have a separate RG6 run to connect to the OTA module. Therefore, I want to use a pair of diplexors.


Are there any concerns with using diplexors in this configuration? Do I need to put DC "blockers" on the links to the antenna? What about placement of the diplexors? Should I place them before or after the SW21?


Any help is appreciated.

You should install the diplexors after the SW-21. You do not need to worry about DC blockers at all.

Perhaps I'm oversimplifying this, but if you've got an amp on your antenna, you can't run power back up through the diplexor.


I've got two that I bought from Dish Depot that I can't use because of this.

Makes sense Randy. I was afraid of damage to the sw21 switches or LNBs, etc.


I just can't find any good reference material on this stuff.


I only have a single run to the sat receiver and I am pretty sure I will need an amp to pick up anything. I am going to try some high powered indoor antennas that I can high somewhere around the entertainment center.

Take a look at the Channel Master 4007IFD ( www.channelmaster.com ). This is a combination diplexer and antenna pre-amp that will use the DC passed from the satellite receiver (it comes with an independent power supply-for use only if for some reason you don't get enough DC). I have a setup similar to yours, and this is what I use. There are 3 inputs: two sat (if you have dual LNBs), and one antenna. The antenna feed is amplified and added to both sat feeds. Two outputs, to feed two sat receivers.

I bought mine from www.warrenelectronics.com
