There’s no perfect solution but it is possible to extend a DIRECTV SWM line further than the traditional 200′ if you are willing to make compromises. We’ve given you the complete guide on DIRECTV cable lengths, and it’s true that there’s a real limitation when you look at the distance between the SWM and the receivers. For the most part we don’t recommend runs longer than 150′ so that whole-home sharing is as smooth as possible, and 200′ per run is really pushing it. (The total run between receivers shouldn’t be more than 300′, so if one run is 200′, the other should be 100′.)
If you’re willing to give up whole-home and all interactive and on demand services, you can get a little further. This may help you get DIRECTV service into the garage or back bedroom where you don’t need those services.
You’ll need a SWMA2-T amplifier from Sonora. Put this somewhere between the SWM and the receiver where it will have access to power. It adds 14dB gain, which should let you take that run out to about 300′ from the SWM. However, with great run length comes great responsibility; if you extend the run past the whole-home’s system ability to function, you’ll have problems, so you need to completely disable whole-home on that long run. Put in a band stop filter anywhere on that long run (the preferred location would be right on the splitter where the signal starts and it will block the DIRECTV networking signal from going down that long cable. This will make your other receivers work better but completely block the ability to do anything but watch live TV or record from satellite.
It’s also true that you can’t stack amplifiers… one is pretty much the limit since you’re not amplifying the SWM control signal that goes back down the line. It’s not a perfect solution as we said, but it’s better than nothing.
