Original DN LNBs?

[bigbro]

I am looking to purchase a couple of new LNBs. I have come across, what seems to be the same LNB, but one is *High Quality* and the other is not. Is there a difference? Is there a high quality and standard quality DN legacy LNB?

Not sure what your set up is but a simple good quality standard 11250 does well and they are easy to set up and aren't power hogs.
You will need one for each bird you want to pick up.
As for your question Terryl I'm sure would have a technical breakdown when he sees this thread.:thumbsup:

DN did not make a "High Quality" LNB only the old legacy, standard DP or DPP types.

Whats wrong with the LNB's you have now?

Remember the first rule of satellite testing, "if it ain't broke now, don't mess with it"

I lose the signal to one receiver when the second receiver is turned on.

That is not LNB problems, this has happened a lot of times, 1 FTA receiver over powers the other one, to fix this problem you need to ground your dishes with switches to a good ground thingy, if this doesn't solve it then you need a DiSEqC switch 44 wish it has power inserter and will stabilize all the receivers to work in Harmony, but again let Terryl advise you with this, after all I am always learning about switches from him.............................Turbo

Thanks for the info, I will wait and hopefully Terryl will advise.

OK, what may be your problem is the switch (or lack of a switch) it has to be a legacy switch (if you have legacy DN LNB's) it should be an SW34 or an SW44, and not a DP34 or a DP44, the legacy system works on a DC voltage switching between the transponders, trying to use something like a 22 KHz switch to switch between two receivers and two old legacy LNB's may cause one receiver to quit working.

The correct setup would be an SW44 with two coaxes going to both outputs on both LNB's, (sat 1 A/B, sat 2 A/B) then one coax to each receiver.

I am currently using two DiSEqC 4x1 switches, one for each receiver. Is that wrong?

[Crazy Horse]

you need to ground both of your lines between the switch and the boxes.....

How exactly is that done?

I went through this problem before, tried different diseqc switches, grounding etc. The simplest method I found that worked for me with 2 receivers was to use a diseqc and sw21 switch. A sw44 would be preferable as Terryl mentioned.

Wont work with the old legacy LNB's, the two receivers will confuse the heck out of the LNB's.

Again the legacy LNB uses a DC voltage to switch between the two transponder polaritys, the legacy LNB has 2 outputs, one uses 13 volts to get the V or R transponders, and 18 volts to get the H or L transponders.

Using 2 DiSEqC switches tied to one port each on the legacy LNB will only get one or the other, but not both, you need the legacy SW44 switch to do this, it takes the two outputs from both LNB's and keeps the signals separate, then the two (or more) receivers can access the two satellites and get all the transponders from both satellites.

You can use a DiSEqC switch on legacy LNB's but only one receiver can access the LNB's H/L or V/R transponders at a time on ether LNB.


This is why DN came out with the DP twin and DP plus LNB's, you can run 2 receivers off 1 LNB, (3 with the D1000 LNB, or 4 with the DP quad LNB) or with a DP21 switch on both DP twin LNB's you can run 2, adding the DP44 switch added 2 or more receivers, and 2 more satellites.

It also allowed for longer runs from the dish to the receivers.

OK, thank you. What do I need if I have two dishes, one with two dual Legacy LNBs for DN and one with one dual Legacy LNB for BEV? The BEV dish is only connected to one receiver, the DN dish is connected to two receivers. Currently I have two DN LNBs and one BEV LNB running to a DiSEqC switch then to one receiver and two DN LNBs running to another DiSEqC switch then to the second receiver.

You need an SW64 (3 legacy LNB's to 4 receivers**) only way to properly combine the two legacy systems, now don't get a DP switch, they wont ork with legacy LNB's, the switch has to be a legacy switch.


** 2 outputs from each LNB, +14 volts and +18 volts, for 3 legacy LNB's this will be 6 inputs into the switch, two from each LNB.

Now this got very cumbersome,(to many coax connections) so Dish cam up with the DP LNB, you only need a 3 input switch for 3 satellites, a standard DiSEqC switch will work fine for 1 receiver, a 3x4 switch will work fine for two or more receivers.

What I also should have asked is, do the SW44 and SW64 switches work with Sonicview receivers?
