lnb power alternative

[canucks604]

are there any alternatives to power the lnb ?
basically i get no signal when i hook up the lnb to the dvb card, i must hook up one of the wire to the ird for the dvb to work.

so for example if i want 119...one wire is connected to the dvb and the other to an ird

i'm using a dp500 with 2 dual lnb

any other dp500 & twinhan user got it to work?

please advise.

Hmm,my Twinhan seems to power my DPro twin just fine. Signal isn't that high(65-70) and I do get fade during rain.
How many watts is your power supply?
There are a couple of in-line signal boosters availabe. One has a power cord that plugs into the wall. Don't know how well they work but it might be worth a try.

power supply is 350 or 400watt, can't remember, also do you think the ini file have to do anything with it? in any case, can you send me a copy or tell me where to get the ini that you are using? and the settings, i want to see if that it will help.

thanks

I got a Twinhan (old, prior to 1020 even) clone and it works fine. No other boxes or anything on the lines. I'm only about 10-15 ft of cable from my dish though, so I got great signal and a very short run.

Dishpro Quad on mine. I think you need to recheck your settings is my guess.

The LNB should be easily powered by anything thats available, the only thing I can figure that might not work is an overly long run, and the DN box can output more for the longer run than the DVB could, thats the only hardware issue I would think might be there, other than that, I'd guess software / settings issues more often than not in this case.

350 to 400W should be plenty.The ini I use is for a Dpro twin.Don't know if that will help but I'll e-mail it to you if you want.
. And I'm using the standard length of coax cable + and extra 4ft. section. I'd guess 20 to 25 feet.

Do an internet search for satellite power inserter.

[smilingjack]

They make a power unit for some complex dish / LNB installs where the switches can not be isolated, try legit dealer sites like prosatellitesupply.com/

The problem they are having is that an IRD puts out 24v DC to the LNB.
The DVB cards are only capable of 12v DC.

12v DC is just enough to power the lnb to get a signal.
24v DC will take a 71% signal on a dvb to 97%.
Add an amplifier to that and you should rarely get fades.

With a poor signal the MPEG decoder has to work overtime and so as well does the emulator.

A power inserter (and an optional amp) will give you a good reliable picture, even with an econo DVB card.

Interesting considering I have only a dvb card hooked to a DPtwin lnb and all is good here!

I would say the problem is their puter isn't outputting enough power. A good 350W PS still beats the sh*t outta a cheap 500W PS.

Not sure if this is true,but some people are using a Dishnet IRD connected to the other connection on the back of the card to get extra power.I can't test this because my ird is legacy and my lnb is Dpro.

Just a note on power supplies in the computer. If Power being out put by the power supply is dependant upon the load attached to the power supply. The power supply attempts to maintain a constant Voltage out. I the load is to heavy for the power supply then the voltage will begin to drop which potentially creates a cascade effect which will affect other components (ie. Harddrive, and processor) before it affects a DVB card. Do a little research before providing an answer. Thank-you,

what kind of card is it
i have 2 twinhan 1022a that have this problem
BTW DONT get a 1022a they are garbage
retailer is supposed to replace them since i ordered the 1020a
u can put receiver on other line on the lnb and that will power it
then the dvb works fine

PS
forum looks nice updated and is running pretty smooth
SWEET

I did that's why I said ....

You're welcome!

Has nothing to do with the power supply of their computer.

The dish pro lnb requires 19 vdc. DVB cards output 13 vdc for vertical polarization and 18 vdc for horizontal polarization transponders. This means that if you are using a DVB card with a dish pro lnb (vertical polarization), the dish pro lnb is not being sufficiently powered (missing 6 volts).

If you place an lnb power inserter or a dish receiver in-line with your DVB card to power the lnb, you must also insert a DC voltage blocker (buy one at Shady-O-Rack) at the input connector of your DVB card. Otherwise you will be pumping DC back into your DVB card. Not a good plan.
