DVR with RV dish

[HoTat2]

Is there anything wrong with this RV setup with two HR24 DVRs?
One coax from single-LNB RV dish to SWM8 switch (not sure which port to connect to),
one coax from SWM1 port on switch to two-way SWM splitter,
coax from each leg of the splitter to the sat1 port on each of the two HR24 DVRs (sat2 port not used),
power inserter installed between one of the DVRs and the splitter.
Would this work?
Sidenote, the RV dish has two output ports. I don't know if I should connect one or both to the SWM8 switch.

The SWiM-8 switch requires at least two coax cables at the inputs. In your situation they connect to the 99°/101° odd and even input ports.

And the PI may be placed where you suggest as long as the splitter itself connects to the "SWM 1/PWR" port of the switch and the PI to the DC power passing port of the splitter.

Or you may dispense with the inline option and simply connect the PI to the legacy port 3 of the SWiM-8 switch which also serves as the ext. power port for the switch.

Running two lines from the RV dish to the switch isn't a problem. However, the RV dish isn't capable of receiving signals from the 99 sat. It can only pick up the 101 sat, so the two lines would be feeding the switch the same sat. Is that a problem?
BTW why does the switch need two lines?

No ...

The "99°/101°" labling on the SWiM switch just means that the down-converted satellite frequency bands from the LNB for the 99° and 101° satellite positions both share the same coax lines, but on different frequencies.

101° - 950 to 1450 MHz

99° - 250 to 750 MHz (Ka-lo band)
1650 to 2150 MHz (Ka-hi band)

Since you only have a standard round dish for 101°, there are no signals from 99° on the coax cables. Therefore, the switch will only see the 101° signals between 950-1450 MHz.

So what's the second line for?

 

[texasbrit]

One line handles the odd numbered transpondrs from 101, the other one handles the even ones

 

[HoTat2]

One line is for the even numbered transponders the other for the odd numbered.

Both sets of transponders operate within the same 950-1450 MHz frequency range, but are kept separate by being transmitted from the satellite on opposite polarities (or polarizations).

Even numbered tps. use "Left-Handed Circular Polarization" or "LHCP"
And the Odds use "Right ..." or "RHCP."

The LNB can then split the two sets and send them on over two coax cables to the switch.

Makes sense. I always wondered why Directv dishes always had four lines going to the switch regardless if the dish had three or five LNBs.
BTW the RV dish that will be used is compatible with both Directv and Dish Network so I don't think its LNB is made specifically for Directv. Will it be able to split the polarized signals?

Yes

The need of four lines from both 5 and 3 sat. position legacy LNBs are to convey the Ka and Ku bands from 99, 101, 103, 110, and 119 from the 5. And the Ka and Ku bands from 99, 101, and 103 from the 3 thusly ....

SL-5 LNB:

Line 1 - Even tps. from 101° Ku, 99° Ka-hi, and 99° Ka-lo
Line 2 - Odd tps. from 101° Ku, 99° Ka-hi, and 99° Ka-lo
Line 3 - Even tps. from 110° Ku, 119° Ku, 103° Ka-hi, and 103° Ka-lo
Line 4 - Odd tps. from 119° Ku, 103° Ka-hi, and 103° Ka-lo

SL-3 LNB:

Line 1 carries same as above.
Line 2 carries same as above.
Line 3 - Even tps. from 101° Ku, 103° Ka-hi, and 103° Ka-lo
Line 4 - Odd tps. from 101° Ku, 103° Ka-hi, and 103° Ka-lo

And for the record nowadays ...

SL5RB (a new six outlet Reverse Band capable legacy LNB) for connection to the new DSWM-30 multiswitch:

Lines 1-4 same as with the SL-5 above
Line 5 - Even RB tps. from 99° and 103°, and 95° Ku if necessary for the World Direct dish when used.
Line 6 - Odd RB tps. from 99° and 103°.

Am I right in assuming that if I get an RV dish with only one output port and use a splitter to feed the two ports on the switch from the one port on the dish, it won't work?
And now you got me curious, why does sat 101 move to lines 3 and 4 on the SL-3 LNB if its already on lines 1 and 2?

Its a little complex, but simply put it comes from the era of legacy (non-SWiM) installations where to this day guide and authorization data for the receivers come from tps. on 101° Ku satellites and are mirrored at a slower rate on the 119° Ku sat. tps. as well.

So with a SL-5 LNB whenever you tuned to a channel on the 103° Ka band satellites the receiver would access guide and aut. information from the 119° Ku satellite.

And when you had a SL-3 LNB, since there are no 119 Ku band signals available for guide/aut. info. when you tuned to a channel on the 103° Ka satellites. The internal circuitry of SL-3 LNB was modified to mirror the Ku signals from 101° to lines 3 and 4 so the receivers could access guide/aut. data from that slot while tuned to a channel on 103° Ka.

In the later SWiM installations the switch always receives guide/aut. information from 101° Ku and never uses the 119° or 101° Ku band signals on lines 3 and 4 from either a SL-5 or SL-3 LNB.

Really fascinating. I love this stuff.
Now I know I need an RV dish with two ports. But the Winegard SWM8 switch runs $190. Do you know what happens if I connect the HR24 DVRs directly to the RV dish without the switch?
Also, do you agree with the guy above that RV dishes not made specifically for Directv will be able to split Directv's polarized signals?
Sorry if that's a stupid question but the dish I'm looking at is pricey.
Last question, do you know of a way to get a Genie to work with this setup?
Thanks

Another couple of things to consider.
1) The dish isn't really a two receiver dish, in that the second output always uses the same sat as the primary output. If you are only looking for 101 that in't a problem, but you can't get 101 and 119 from the dish at the same time.
2. If you try to use SWM you might have a big problem. To do this, you would select SWM and the 18in dish. Unfortunately, DirecTV has already removed this option from the Genie menu, and might have done it for the HR24 also. If so, there's no way you can use SWM for the Winegard dish. You need to check on this otherwise you would be throwing away your money on the Winegard SWM adapter, unless Winegard can persuade DirecTV to reinstate this menu option. So with two HR24s you would be stuck with the need for a WB68 (nonSWM) multiswitch, with two cables to the dish, and two cables to the WB68 from each HR24.

That's exactly my concern. My original plan was to setup a Genie because the Winegard website says all three Genie models are compatible with their dishes. But that's changed. I can live with two HR24s (the Genie would have been nice) but I have no way of checking if what happened with the Genie software also happened to the HR24. I also don't know how or if the HR24 would work if connected directly to the RV dish without the SWM8 switch. Your idea of using a non-SWM switch is one I hadn't considered. Would all four tuners across the two HR24s work with that switch and an RV dish?
The good news is I only need to pick up the 101 sat so there's that at least.

 

[texasbrit]

You could connect one HR24 directly to the dish or two if you use the WB68. Specify "multiswitch" and the 18in round dish.

Is there anyway to combine the two lines between the switch and the HR24 into one coax and then split them again for the connection to the HR24?

 

[HoTat2]

No ...

And remember you'll also have to connect a B-Band Converter (BBC) in each line from the legacy multiswitch to the HR24 receivers.
