I was wondering what LNB/LNBFs were available that cover that range of frequency... I'm pretty sure there's a Norsat LNB, at Norsat price, which makes it a bit hard to justify the expense considering that there's not much on those frequencies.

Is anyone aware of a more affordable option?

Tek2000 has an LNBF that has ambiguous description, that made me think that it would cover that band, but after looking it up from other resellers, it's seems it's just a stacked LNBF that uses a 5750 LO to cever the second polarity

Has anyone considered modifying an existing regular C-Band LNB to change the LO to 5750 MHz? I'm guessing that would be difficult without proper measuring equipment, but maybe not impossible?

Developed a 3.7 - 4.8GHz PLL model several years ago that is currently under license by a satellite corp. The license will expire in 2020 and may manufacture under Titanium Satellite brand if the market expands.

At this time, very few services have footprint in the US or Canada using this frequency range. The South American footprints cover the southern regions of the US. Had a useable, but with very low SNR in Northern California.

The feed and probes for a standard LNBF provided poor performance in the higher range. While the stubs can be shortened for the higher frequency, the larger feedhorn cavity was problematic and cross pol was quite poor.

There are several satellite equipment resellers in South America with inexpensive LNBF options.

BTW... the Anhui Bowei 4500 - 4800 MHz LNBF model is not only cheap, but also features absolute crap performance. Yes, this is the same factory that cloned our PLL LNBF and now directly sells on Ebay. [emoji852]

The licensing agreement was renewed. Little demand in NA market to manufacture and stock a similar model.

You can purchase high band C-band LNBFs from South America and I've seen them sold on Ebay with shipping from China. Not sure of the quality, but the cost is reasonable if you want to experiment.

I know this is a long dead thread, but with talks of spectrum auctions and such, is 4.5-4.8 still viable? Or was it auctioned off as well previously?

as far as I know, there's capacity in that band on 4 satellites that cover North America:
- Hispasat 6 @30W (not 100% certain, and I have never seen any info of it being used)
- SES6 @ 40W (it was being used at some point, but not seeing anything listed at this time)
- Amazonas @ 61W - according to PortalBSD there are data transponders
- Eutelsat 65 WestA @ 65W - dozens of mostly Brazilian channels

Note that I'm not able to receive it so this information is based on what's on Lyngsat and PortalBSD

So it looks like it's alive and well, but not growing. It's also clear it's not aimed at North America, we just happen to be included in the footprint, at least partially

I don't know if that band is licensed to satellite use in North America, so it might not even be an option to be actively used here.

On the technical side, with a regular C-band LNB with LO=5150 MHz, the 4.5-4.8 band translate to 350-650 MHz, which is of course too low for regular satellite receivers. So I have hooked up an SDR dongle to be able to look at the spectrum. While most LNBs filter that band out, I have an old Norsat that does not, and was able to see at least part of the transponders on 65W. I tried adjusting the LO frequency in the LNB, but could get only minor adjustments (about +/- 10 MHz), far from what would be needed

While this isn't a FCC list, it should be helpful.



Also, a transponder's technical capacity of operating in a band doesn't necessarily mean there is an associated license to operate. You would need to deep-dive further on the spacecraft details.

Everyone else's mileage may vary.

c band


Another consideration is the microstrip bandpass filter. A magical world at least for me.
I haven't swept a c band satellite that is "busy". During football season 89W would be interesting because almost every time you scan it, there are new tp's and sr's popping up. Sometimes (usually) only for the event. I blindscanned it last night and it was almost dead.

A TinySA is fun to play with as is something like the SDRPlay spectrum analyzer application. A fancy bias-tee isn't needed for either one because you're non doing lab work. You're snooping around.

A signal source is needed. A 'junker' or spare c band lnbf and capable signal generator/service monitor with generator, or known active transponder in the extended band would let you dick around with the bandpass filter. I'd have to look deeper into the block diagram and photos of the pc boards.
Ku band lnbf teardown and LO mods are all over the 'net. C band? Not so much.
Who knows. I'm sure the bandpass filter isn't a "brick wall" and there is a bit of an attenuation slope on both sides of the filter.
A bypass capacitor? Jumper the filter? X-Acto knife to break the filter traces in small chunks and see if upper band signals increase using an SA and normal lnbf. You never know.

Browns lose a close one with... The Jets. That is a classic Browns loss (granted, any loss is a classic one it seems). 49'ers, Vikings, and Chiefs remain undefeated. The AFC north have a three way tie at 3-2 for second place. :eek:

24 team playoff seems to be real close.

Are we really that far from a 64-team tournament?

The benefit of the 24 team playoff:
  • All the cartel teams that cartels want in playoff are in playoff
    • Independent of record too! Bonus.
  • MONEY!!!!! for the cartels.
  • I'm out of ideas.
Cons
  • Regular season really doesn't matter now other than the rivalry games
    • Top cartel teams can lose three games and still make the playoff
  • Going to start resting players?
    • The playoff is going to be *checks notes* several games!
    • Resting players could make games dumb.
    • Maybe even restrict NIL players from games played.
  • How much are streaming sub costs going up a month to pay for this?!

One of the pro's I see is in a year with so many undefeated teams they have a good chance of an opening. Few years back you had lower divisions that didnt get a shot. I love collage football and I have no problem with that addition.

We are in what week 5 now? Been two real good ranked games to watch.....Other than that top 25 teams are playing nothing.

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.

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.

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…

Sometimes a thread gets so many posts in it that is can cause issues for the server so that why today we introduce The Song Name Game Part 3!

So let the game continue!

The last song was added by Bobby who posted...

One Meat Ball - Andrews Sisters

CONTINUE ON AND HAVE FUN! WELCOME HOME TO SATELLITEGUYS.US!

Here are the original rules for the game as posted by WebbyDude back in 2006. http://www.satelliteguys.us/threads/68645-Song-Name-Game

Just name a song title and the band who performed it. The next person does the same thing, but needs to list a song title or band name which includes a word from the previous entry. Pick songs from any genre.

Example:

Long Live Rock and Roll -- Rainbow

Rainbow in the Dark -- Dio

Another example:

Ride the Lightning -- Metallica

Lightning Strikes -- Ozzy Osbourne


Get it?


An additional note: we all know that song titles, sometimes, use profane words. Because this is a family friendly website it is advised that you clean up that title up a bit. This is accomplished by using something like sh!t instead of the real word. Thanks....

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

It also has a IPS and a OPS switch on the side of it with a power led light showing when is on. It seems to be very nice build switch
