(SWM) Single-Wire Basics - See Products Below

DirecTV (Single-Wire) SWM Technology Simplified: Prior to the introduction of DirecTV's Single Wire MultiSwitch (SWM) Technology, it was necessary to run two cable drops from the dish or multi-switch to a dual-tuner DVR.  In a high percentage of those installations, running two lines in a prewired home was difficult, especially those homes built on concrete slabs or homes designed with vaulted ceilings.  To service rooms with exterior walls, installers were forced to "wrap the house" with unsightly wire. Interior rooms required snaking the cable underneath carpet or fishing it through an interior wall. SWM Technology allows two individual signal-feeds to effortlessly travel down a single wire to the dual-tuner DVR. SWM technology is available only for the SlimLine dishes - also limited to the newer model receivers designed specifically to work with the SWM technology.  DirecTV's 18-Inch Round, ParaTodas (Phase II), and Elliptical (Phase III) dishes will NOT work with this technology.

Converting the Standard 4-Port SlimLine Legacy LNB to Single-Wire Technology
OPTION #1: If you're currently using a standard SlimLine dish (AU9) utilizing legacy technology, you can convert the dish to single-wire technology by simply exchanging the 4-Port Legacy LNB (SL5) for either a 3-Head LNB (SL3S) or a 5-Head LNB (SL5S). Choosing the correct replacement LNB is determined by your DMA (Designated Marketing Area for local broadcast channels) and also any channels you may be subscribing to that's beamed from either the 110° or 119° satellites. The SL3S receives signals from 3 DirecTV satellites (99°, 101° and 103°). The SL5S receives signals from 5 DirecTV satellites (99°, 101°, 103°, 110° and 119°). If you're not sure what's required for your particular DMA or the hi-def channels you receive, go with the 5-Head LNB (SL5S). OPTION #2: You can also convert the Standard 4-Port SlimLine LNB to Single-Wire Technology by inserting an SWM-8 MultiSwitch. If you're utilizing multiple satellite dishes to receive signals from other DirecTV satellites (95° or 72.5°) - you must use the SWM-8 Multi-Switch to incorporate those signals.

Converting the AT9 (KaKu) Legacy LNB to Single-Wire Technology
It's possible to convert the older DirecTV AT9 satellite dishes with multiple LNBFs to SWM technology by using the SWM-8 Multi-Switch. We do NOT recommend exchanging LNBs on this particular satellite dish antenna. If you're not into multi-switches and would prefer an SWM LNB - you'd be well advised to change out your KaKu (AT9) dish to a SlimLine (AU9) dish. Be Warned: if you remove the LNBs and attempt to realign the AT9 dish, you're going to need experience, a high-dollar satellite meter and nerves of steel to get your dish realigned. We highly recommend you insert an SWM-8 Multi-Switch (offered for sale below) and leave the dish where it is - don't adjust the direction, elevation or skew unless you are a trained professional installer!

SWM Compatible Satellite Receivers
There are several receivers that are compatible with the SWM options on the market. They are the HR20-100 through HR20-700, HR21-100 through HR21-700, HR21 Pro (in all models/configurations), HR22-100 through HR22-700, HR23-100 through HR23-700, HR24, H20-100 through H20-700, H21-100 through H21-700, H22-100 through H22-700, H23-100 through H23-700, H24, R16-100 through R16-700, R22-100 through R22-700, R23-100 through R23-700, D12-100 through D12-700, and D13-100 through D13-100.

SWM Splitters
In practically every installation, a splitter is required whether you're using an SWM LNB or an SWM Multi-Switch. The only time we've gotten away without using a splitter is a one-receiver DVR installation - running straight from the SWM LNB to the SWM Power Supply to the receiver. ALL multi-receiver installs will require a splitter. The number of receivers to be installed will determine the type SWM Splitter needed (2-way, 4-way or 8-way). SWM Splitters are unique - you cannot use ordinary splitters in your installation!

SWM Power Supply
All SWM installations will require the use of a power supply. Satellite Receivers will not power the SWM LNB or SWM Multi-Switch. Power supplies are NOT interchangeable. The PI-21 Power Inserter must be used for the DirecTV SWM LNB and the PI-28 Power Inserter must be used for the SWM-8 Multi-Switch. ALWAYS read the instructions thoroughly and follow the directions step-by-step when inserting the power supply. Failure to do so may damage the receiver! Sending SWM power from the Power Supply to the IRD (receiver) can damage or destroy the receivers. Power supplies have two ports: Port #1 marked SWM supplies power to the SWM LNB or MultiSwitch; Port #2 marked IRD (Integrated Receiver Decoder) is the receiver side - do NOT REVERSE these connections and send power toward the IRD (receiver) - double-check your connections before you plug the power supply into an AC power receptacle.

SWM Dish, LNBs, Power Supply and Splitters

DIRECTV® Slim Line Satellite Dish Antenna without LNB $79.99
Satellite dish assembly (NO LNB). Includes house mount, back assembly, reflector plate, LNB mounting bracket and monopole support. Compatible with both the SL3S (3-HEAD) SWM LNB and SL5S (5-HEAD) SWM LNB (sold separately).  Dish ONLY!  LNBF is NOT included with this purchase.  See LNBFs in panels below.

DIRECTV® SL3S (3-HEAD) SWM LNB - $79.99
For use with the AT9/KaKu or AU9/SlimLine DIRECTV dishes. Receives satellite signals from three DirecTV positions: 99°, 101° and 103°. Allows two-signals to travel down a single coaxial cable to feed the DirecTV DVR. Necessary equipment in homes where running a second coaxial drop is not an option. The PI-21 Power Supply is required for this LNB. Specially designed splitters can be used in conjunction with this SL3S (3-HEAD) LNB to feed multiple satellite tuners (a DVR has two tuners in a single housing). If you're not sure which LNB is required for your particular DMA or the hi-def channels you receive, go with the 5-Head LNB (SL5S) below.

DirecTV® SL5S (5-HEAD) SWM LNB - $89.99
For use with the AT9/KaKu or AU9/SlimLine DIRECTV dishes. Receives satellite signals from five DirecTV positions: 99°, 101°, 103°, 110° and 119°. Allows two-signals to travel down a single coaxial cable to feed the DirecTV DVR. Necessary equipment in homes where running a second coaxial drop is not an option. The PI-21 Power Supply is required for this LNB. Specially designed splitters can be used in conjunction with this SL5S (5-HEAD) LNB to feed multiple satellite tuners (a DVR has two tuners in a single housing). If you're not sure which LNB is required for your particular DMA or the hi-def channels you receive - be safe - go with this 5-Head LNB.

DirecTV® PI-21 Power Inserter for SL3S and SL5S SWM LNBs - $21.99
The PI-21 Power Inserter is specifically designed to work with either of SWM LNBs featured above (SL3S and SL5S). Receivers will NOT power the SWM LNB - you must use a power inserter. ALWAYS read the instructions thoroughly and follow the directions step-by-step when inserting the power supply. Failure to do so may damage the receiver! Sending SWM power into the IRD (receiver) can damage or destroy the receivers. STOP!, and double check to make certain your connections are accurate prior to plugging the power supply into an AC outlet.

DirecTV® 2-WAY, 4-WAY and 8-WAY SWM Splitters - Priced Accordingly
are designed for use with DirecTV Single Wire Technology.  These are NOT common splitters and are NOT stand-alone products - use only in conjunction with the DirecTV® SWM8 Single-Wire MultiSwitch or the DirecTV® SL3S (3-HEAD) or the SL5S (5-HEAD) LNBFs.  Splits single output port on the SWM switch or LNBF - creates two, four or eight output signals for select receivers.
