SatelliteSale DIRECTV SL3‑SWM SlimLine Triple LNB with SWM

The DIRECTV SL3-SWM SlimLine LNB by SatelliteSale is a triple-feed Ka/Ku LNB with an integrated single-wire multiswitch that supplies multiple satellite feeds from a single Slimline dish connection.

The SL3-SWM combines three LNB heads (for the 99°, 101° and 103° orbital slots) with a built-in SWM (single-wire multiswitch), letting compatible receivers access multiple satellite signals without running multiple coax cables. Designed for DIRECTV Slimline dishes, this LNB simplifies wiring and expands multisatellite reception. Note: the SWM requires a PI-21 21V power inserter (sold separately) to distribute power and switch control to connected receivers.

How does the SL3-SWM let one cable serve multiple receivers?

The SL3-SWM contains an integrated single-wire multiswitch that encodes separate satellite feeds onto one coaxial cable, enabling multiple tuners to access different satellites over the same run. Each connected receiver uses protocol signaling and the PI-21 power inserter to request the desired feed.

• Built-in SWM merges three satellite signals onto a single cable
• Receivers use SWM signaling to tune specific orbital slots
• PI-21 power inserter supplies power and control to the SWM (sold separately)
• Reduces cable runs and simplifies attic or wall conduit routing

Which satellites and frequencies does this LNB receive?

The SL3-SWM is built for DIRECTV multi-feed Slimline setups and receives signals from three orbital positions: 99°, 101° and 103°. It covers the Ka/Ku frequency bands used by DIRECTV programming when paired with a Slimline reflector and compatible receivers.

• Three LNB elements aligned to 99°, 101°, and 103° orbital slots
• Supports Ka and Ku band reception as used by DIRECTV systems
• Works only with Slimline dish assemblies designed for triple-feed LNBs
• Requires correct pointing and professional-style alignment for best reception

What installation and accessory considerations should I know?

Installing the SL3-SWM follows standard Slimline dish procedures, but you must provide the PI-21 21V power inserter to send DC power and SWM control signals over the coax. Mounting, cable quality and proper aiming strongly affect signal reliability—use weatherproof connectors and high-quality RG6 for best results.

• PI-21 power inserter required (not included)
• Use weatherproof F-connectors and quality RG6 coaxial cable
• Professional alignment recommended for multi-orbit setups
• Compatible only with DIRECTV Slimline dish reflectors and SWM-aware receivers

Who is this for? The SatelliteSale DIRECTV SL3-SWM is ideal for homeowners or installers who use DIRECTV Slimline dishes and want to simplify wiring while receiving all three nearby satellite positions. It's a practical choice for multi-tuner households, remodels where running extra coax is difficult, or installations seeking neater cable management. If you already have a Slimline reflector and compatible receivers, adding this integrated SWM LNB reduces complexity; just be sure to purchase the PI-21 power inserter and follow proper alignment practices for reliable service.
