Free-To-Air Satellite Systems


The following information was submitted by a customer. It is published here for informational purposes only. We cannot and do NOT condone or recommend using free-to-air satellite equipment to capture subscription channels.

The Coaxial Cable Power Inserter (120 VAC Input to 24 VDC Output) works great and it solved my multiswitch problem!! A great many people have issues pertaining to Dishnetworks "DP34 Multiswitch" with signal dropping out because they are NOT providing enough voltage to this power hungry multiswitch. In most cases they may be running only 1 satellite receiver, or the type of satellite receiver they have hooked up to other coaxial outlets are still not providing enough power to the multiswitch. This issue occurs most when using most models of "Free To Air Receivers" which generally are ok for providing enough power when connected straight to the LNB (no multiswitches at all). The DP34 was designed to support "daisy chaining" and as such is power-hungry. You will find that many people buy the DP34 Multiswitch versus the DP44 model due to the price difference. The DP44 has its own special DP Pro Power Inserter to supply to it dedicated voltage so people dont experience the signal drop out problem and intermittent issues as with the DP34 who depends wholly on voltage provided through the coax cable. I did a ton of research on this popular multiswitch the DP34 and was able to discover that it requires a full 19.6 volts to be fully powered, it has built in circuitry to "bleed" any excess voltage above that threshold, thus your 24V coaxial DC Power Inserter provides dedicated power to it flawlessly. I wanted to share this additional information with your company so you can note it in your Ebay Auctions and on your website so that others who pulling heir hair out trying to figure out what's the problem with their DP34 Multiswitch signal drop out problems, can know this. I'm sure if you were to mention this you would increase sales further, because the Dishpro Power Inserters designed for the DP44 Multiswitch that can be purchased separately are not only inferior and more tedious design but are also more expensive.

Satellite MultiSwitch: Expanding Your DirecTV Satellite System

Expanding The DirecTV 18-Inch Round Satellite Dish Antenna from 2 Ports Out to 4 Ports Out, 8 Ports Out, or 16 Ports Out

Orbiting high-powered satellites broadcast satellite signals in two polarites: right-hand polarity and left hand polarity. Commonly referred to as even transponders or odd transponders, the signals are sent in a spiraling motion, either clockwise or counter-clockwise, on a path toward earth.

A dual-port LNBF can intercept and feed these satellite signals to two satellite receivers. Each satellite receiver works independently of the other, sending voltage controlled signals to the LNBF, switching the LNBFs polarity to accept either the odd transponders or the even transponders.

A multi-switch is designed to lock one of the LNBFs ports to accept only those signals being broadcast in odd polarity. The LNBFs other port is locked to accept incoming transponders that are being broadcast with even polarity. In simple terms: it designates one LNBF port as "even" and the other LNBF port as "odd".

After installation, the satellite receivers voltage-controlled commands are intercepted by the multi-switch and internally directed (or switched) to either the LNBFs odd port or the LNBFs even port.

Input Ports: Voltage-controlled multi-switches ordinarily have 3 ports in – the third port accepting signals from either an off-air antenna or cable TV feed – and combining those signals with the signals coming in from the satellite dish. However, those mixed signals must be separated (using diplexers) before they’re allowed to enter the satellite receiver.

Output Ports: Voltage-controlled multi-switches are traditionally manufactured in multiples of 4-ports out, 8-ports out, and 16-ports out and are designed to operate up to that particular number of satellite receivers.

When installing a multi-switch, it should always be sheltered: under an eave, inside a crawl space, inside a covered box, etc. It should be properly grounded. And, unused ports should either be terminated or sealed to prevent condensation and to protect them from tiny little creatures that are prone to crawl inside and nest.

Using a Single Cable Line for DirecTV Tivo or DirecTV DVR Operation


In high-power DBS (Direct Broadcast Satellite) systems such as DirecTV and Dish Network, each channel is broadcast from the satellite with either a "left hand" or "right hand" circular polarization. An LNBF can only receive one type of polarization at a time. Roughly half of the channels are on one polarization and half the channels are on the other polarization. If you could physically see these incoming satellite signals, they might resemble a giant corkscrew – some are rotating clockwise and some are rotating counterclockwise.

Satellite television channels are broadcast from the satellite on transponders – even numbered transponders broadcast in a “left hand” polarization and odd numbered transponders broadcast in a “right hand” polarization.

The most important thing to understand about DSS systems is that the satellite receiver actually tells the LNBF on the satellite dish antenna which channels it wants by switching the LNBF’s polarization to accept only those channels. It does this by placing a variable voltage on the cable and in some instances a 22 KHz tone to switch the LNBF’s polarization.

Oil and water won’t mix in the same bottle and neither will odd and even numbered transponders in the same coaxial cable line.

It’s not at all an uncommon practice for folks attempting to install a dual-tuner Tivo or DVR to mix these signals. Ordinarily, they’ll use a combiner outside to combine the signals and a splitter inside to separate them. Their reasoning, “the house is already pre-wired and I can’t run another drop from the receiver to the dish.”

And, ordinarily, things will work just fine in the beginning but then “there’s missing channels! – what’s wrong?” So long as both tuners are calling for an even-numbered transponder or both tuners are calling for an odd-numbered transponder – all’s well. BUT, when one tuner calls for a channel being broadcast on an even transponder and the other tuner is calling for a channel being broadcast on an odd transponder – that’s when things don’t work so well.

Oil and water won’t mix in the same bottle and neither will odd and even numbered transponders in the same coaxial cable line.

The economical solution is to run a separate cable drop from the DVR or Tivo to the LNBF outside. However, if that is impossible, out-of-the-question, and you have around $300 to spend, you can use a stacker outside to combine the signals and run them down the same cable drop to a destacker inside to separate them. Stacked DBS signals contain the odd polarity from 950 to 1450 MHz and the even polarity from 1525 to 2025 MHz.


In simple terms, the stacker separates the incoming signals, groups them according to even/odd, then stacks one above the other. The destacker's job is to undo the stacker's job and reconvert the incoming signals back to their original format before they enter the satellite receiver.

Question: Will the stacker/destacker pass HD signals? At this time, the answer is NO but it is my understanding Winegard and some other companies are working on a solution. More about that later.

Question: Where can I obtain information on the DBS Stacker/Destacker? Click on this link and open a pdf document on the Stacker. And on this link to open a pdf document on the DeStacker. You will need Adobe Acrobat installed on your computer to open these file.

DiSEqC Switch & Multi-Switch Failure!


NUMBER 1 CAUSE OF FAILURE: Connecting and disconnecting the switch under power. If you are installing a tone-controlled or voltage controlled multi-switches or DiSEqC switches, ALWAYS disconnect the power from the receiver and any other device that may put power on the coax line. UNPLUG the receiver from the wall outlet. Turning receivers "OFF" by using the remote control or the button on the front panel of the receiver does NOT stop power from going to the LNBF and therefore the switch. UNPLUG THE RECEIVER FROM THE POWER OUTLET.

NUMBER 2 CAUSE OF FAILURE: Water! If your switch has been installed and working properly for some time after installation and fails: check for water damage. Most often, the inside of one or more of the connections will be black indicating water damage. Discount the pictures you’ve seen and the words you’ve read about weather-proof connectors and switches – there are NO water-tight connections! There is a major difference between being weather-proof and water-tight! The switch should be sheltered underneath an eave, inside a crawl-space, or inside a covered control box. NEVER INSTALL A SWITCH OUT IN THE OPEN.

PERCEIVED FAILURE: If you have installed a switch (DiSEqC or voltage controlled) on an existing system and experience immediate failure, it’s because the connected receivers were not unplugged from electricity while you were doing the installation and they are retaining memory of the previous installation configuration. Unplug all connected receivers from electrical power and power them back up – one at a time. If you’re installing Dish Network receivers, you must do a manual “switch check” and allow each receiver to detect the current configuration and store to its memory. And, if it’s DirecTV equipment, you must enter the set-up menu and select the proper dish (round, oval, or KaKu).
