Dual Polarity 3 LNB

Attached is a photo of a system I just put together. I have not tried it yet. Do you think it will work? I am going to test it on Intelsat 19, using a 3.8M offset.

I'm not sure I understand what it is you are trying to achieve... are you trying to do linear on one LNBF and circular on the other?

I don't think that would work, as each port of the orthomode feed would get only one polarity.

Well, what I was trying to do was get two H/V C band feeds and one Ku H/V band feed on two cables. You were the closest on predictions. One C Band H/V LNB did not work at all and the other would only work on only one polarity. So far I have had no joy with Ku band, but not many get to this rock and I have not stopped trying yet. I am not familiar with the Ku specifications of my LNB or what control signals are necessary, and have been trying different combinations. On reflecting why the second C Band did not work at all I realized that the C-Band splitter selects only one polarity and passes the other polarity to the second LNB, which is what your response confirmed. It was aligned to the the incorrect polarity. I turned it 90 degrees and got a signal. I would not call the experiment a failure but definitely a learning experience. I had presumed that the C-Band splitter would send the full band and the alignment of the LNB would select H/V. Right now I have the C/Ku unit only on my dish and it works fine on C-Band, zilch on Ku.

Indeed, in this type of feedhorn, I think the LNB that is directly aligned with the feedhorn has its polarity set by the shape of the tube, as it transitions to rectangular. and if you look inside you see a little metal thing encased in plastic (that thing is really an antenna) that transports the other polarity signal to the second LNB opening.
As for the C/KU combo LNBFs, I had the opportunity to try one on an 8-foot dish, and all I could get was the strongest transponders, such as CGTN on 95W, and JBS on 99W. From what I understand it's basicaly a C-Band LNBF, and they made a hole at the end and mounted a Ku LNBF. But the built-in feedhorn is really tuned for C-Band and the Ku LNB gets limited signal. From what I read, it works fine on some dishes and really poorly on others.
Instead, on my 10-ft dish I attached a cheap Ku LNBF to the side of the C-Band scalar, and it's working quite well. Of course one drawback is that Ku- and C-Band are not aligned, so that's many more entries in the positionner. (I also added a circular polarization feedhorn on the opposite side of the scalar)

I tried the combined C/Ku feed and picked up the C-Band AFRTS encrypted transponder on the dateline Intelsat, but got no Ku. I decided to take the Ku LNB out of the combined unit and and try it on its own. I mounted the LNB in the C Band Feedhorn, at its focal point, so I could easily rotate it to the correct polarization. I got the strongest signal I have ever received here 13.7 C/N. I attached a cable and did a blind scan and picked up 64 Ku TV channels. I think they were all French and most were encrypted. Tomorrow I want to try the same Ku LNB at the focal point of my offset 3.8M dish on Intelsat 19. The photo shows the Ku LNB mounted with packing foam inside the offset scalar feed, ready for the test.

that's cool! Looks likely that you're getting the Canal Calédonie package that's aimed at New Caledonia and at Wallis and Futuna islands (just like we're getting Canal Caraibes from here).

I checked your location on SatStar.net, and it looks like you might also be able to get some Ku stuff on 152E (JCSAT 2B) - but i don't know if there's any content there.

As for Intelsat19, looks like you might be outside its Ku beams, but it's certainly worth a try. The small scalar on your Ku LNB might not work so well on an offset dish.

I tried the Ku LNB in my 3.8M offset dish. No signal. I then tried it in a 1.5M dish in case it was just a focal length problem. Still no joy. Today I am going to look at 172B on a 5M dish for a C-Band signal I want to get from PNG. Unfortunately my spectrum analyzer was lost by Satlink when sent back for warranty repair, otherwise I could tell whether a signal is present but just too weak to lock. I keep hoping that SatLink will recognize their responsibility and replace the lost unit, but I may have to purchase another one. Satlink took a long time to "repair" my unit and asked me to be patent because it was the Chinese new year. 3 months later they sent me a tracking number which said the unit was in transit. It was still in transit 3 months later after which the tracking site became extinct. The next Chinese New Year is just around the corner.

OTHER Mini Multiswitch

I just received 6 receiver 2 port mini Multiswitch and it work great, no external power need it, and you can connect 6 receiver instead of 4 on most Mini Multiswitches... If anyone is interested in where they can get one PM me....

Have you tested using external power? Over the years, have found unpowered polarity switching to be unreliable. Especially problematic when used with DiSEqC motors or switch stacking.

No I have not. I just got it the other day and it is connected to six receivers working just fine. What I do is non power mini multi-switches work best with LNBF's and with LNB's

Hughesnet cancelling email addresses

Wasn't exactly sure where to post this. Just had a customer come in inquiring about internet. He has HughesNet and had heard good things about mine. He asked if we provided email addresses and it kinda caught me off guard. I said he should be able to keep whatever email he had been using....my sister in law is still using a BellSouth email addy and they haven't been around here for many years. He said he had gotten a letter from HughesNet stating that they had until Nov 16th to save, move, forward, whatever, their Hughesnet emails because they would lose them after that date.

I have never heard of a company simply mass-deleting email accounts (the customer still has his HughesNet service). From what I understand, in the past, the company who was ditching their email service simply sold the customer base to a company like Google.

Anyone else getting this letter. He said he would show it to me tomorrow when I go out there and set up his internet.

Doing a Google of the HughesNet Email notice, it seems that HughesNet has been trying to eliminate hosting emails since 2019. And with HughesNet filing Chapter 11 back in August, it would be a smart move to switch to a more stable Email provider. Even AT&T farmed out their Email to Yahoo! years ago.

SpaceX's Starlink and the Cellular 5G Home Internet solutions have pretty much relegated HughesNet and its high latency, low bandwidth Internet service to History. If Earth had shorter days, maybe a Geostationary Internet Solution might have stood a fighting chance…

Site is slooooow

For some reason, the satelliteguys.us site is loading a lot slower than usual on both Chrome on my Asus laptop and Safari on my iPhone.
I'm also seeing longer appearances of the blue bar at the top and the "3 blue bars" loading symbol.
Is anyone else also having the same problem? Thanks in advance.

Man falls to his death on roller coaster at 6 Flags in GA

Can't help but wonder if a worker overlooked checking the harness. I rarely ride a roller coaster anymore but when I do I check the harness myself pretty aggressively.
Can't imagine what the son is going through.

Dad levitated and bled then fell to his death from coaster

Eyewitnesses have shared fresh details of the horrific accident that happened at Six Flags Over Georgia on Monday afternoon.

Back on the Goliath Roller Coaster ... I'm interested to find more details as well ...
Like where on the track did this happen (somewhere I read that it was on the climb up the top), which is impossible ...

They really need to take that ride and add at the very least, seatbelts ...

The Park is opening back up on Friday, the ride will Not be opening ... personally, I would keep it closed until different type of restraints can be designed and installed (over the winter).

I find it hard to believe that this ride is even allowed to be running with the restraints that exist at the moment, there are other rides that use the same type and they have been shut down across the country.

You got to believe that every ride has at least 2 types of restraint systems in place.

I wonder what and when we will hear from the Manufacturer ... and whatever governing bodies control these ...

Just think, this is a Major Amusement Park .... I would not have any problem getting on the Roller Coasters I have rode ...

Imagine what these County Fairs and others like them, I would not be caught Dead on one of them ... they get put up and tore down every other week, where is the safety for those rides ... No Thank You.

It makes sense, however, I would want more types of restraints, so if one doesn't work, the other does ... the restraints coming over the shoulder I would have expected ... with a Seat belt as last resort.

Fwiw, I inquired with what they use on Coasters at Cedar Point, various Coasters, different restraints according to what the car and track requires ...

NONE of the Coasters at CP use THAT particular system

I'm glad to see ...

According to the article, when you see a seat belt on a ride like this, it is basically used as a way of making sure the rider isn't too large/fat to safely ride the ride.
