How do you connect a SWM-30 to a Reverse Band dish?

Please be patient, this is going to take some explaining.

If you want 4K in your home, you are going to need special hardware. DIRECTV’s Reverse Band 3 LNB is a replacement for the front of your dish. It lets your dish get those extra frequencies it needs for 4K.

The Reverse Band 3 LNB looks at AT&T’s three primary satellite locations and receives transmissions from three different ranges. (The older LNB only receives transmissions from two, that’s the difference.) It gives you the ability to feed 13 tuners consistently, and if you’re careful with how you power up, you can feed up to 21 tuners.

(Confused about what that means? Here’s a tutorial.)

That should be enough for everyone, right?

What if it isn’t?

If you have a large home and you want 4K, you’re going to have an HR54 Genie DVR, a 4K client, several Genie Mini Clients, and a mix of other receivers. You’ll get past that 13-tuner limit pretty quickly and unless you feel comfortable with a very careful powerup sequence, you’ll run into trouble getting up to 21 tuners.

In order to get past that 13-tuner boundary, you’ll need an external SWM module. The right choice is the SWM-30, which will distribute 4K and HD to up to 26 tuners in your home. In a commercial setting where multiple Genie DVRs are connected, it will serve up to 30 tuners, hence the name.

The SWM-30 accepts 6 lines in for 4K service, 5 lines in for use with an international dish, or 4 lines in for plain old HD service. The Reverse Band LNB has one line out. So how do you do it? How do you connect a Reverse Band LNB to a SWM-30?

Easy answer: you don’t.

SWM-enabled LNBs cannot connect to external SWM modules. This isn’t a new thing: I famously wrote about it two years ago before Reverse Band LNBs even came out. Luckily though there is a solution for people who want that sweet, sweet 4K programming and also want to have a lot of receivers in their homes.

This is the Reverse Band Legacy LNB from AT&T.  It receives broadcasts from the four primary DIRECTV satellite locations, plus the 110 location that’s used for Puerto Rico. It features six outputs, which correspond to the six inputs on the SWM-30. Problem solved.

When installing this LNB, it should be a fairly easy swap-in for the Reverse Band 3 LNB. You may need to do a bit more aiming to get it to see the 119 location to avoid errors popping up, but once you do, connect the lines to the SWM-30 and you’re set.

Lines 1-4 connect to any of ports 1-4 on the SWM. You must connect the fifth line from the left to the fifth port on the SWM. Similarly, you must connect the sixth line to the sixth port. Keep that in mind and you’ll be fine.
