    This is likely 5G, right?

    Thanks. I'll double check that although I've tried too receivers and do live in a suburban area, so I reckon it's 5G. Good reminder to check the basics though!

    This is likely 5G, right?

    That makes sense, although it makes me think the cell tower behind the dish is less likely to be the problem because the dish would block the signal from reaching the LNB, unless it's reflecting off something. But the house is in front of the dish so that should block too. This could be a lot of...

    This is likely 5G, right?

    Thanks Brian, I will try one of those when they are available. Any idea when roughly in January they should be on the site?

    This is likely 5G, right?

    Thanks for the suggestion. Unfortunately, due to a line of very tall trees, this is the only location on the property when I-21 can be received so moving the dish is impossible. What type of mesh might work? The nearest cell tower is behind the dish and I might try a fence there.

    This is likely 5G, right?

    In the last few months, I've been suffering a lot of break-up on Intelsat 21 (58W) 4080V. I keep getting tiling like this. It happens to varying degrees at least once a minute. The signal meter shows a strong signal +14dB and I've peaked the dish but it persists. I'm using one of the Titanium...

    5G US C-band launch

    I'm not sure what bird story you're talking about but there is a fair amount of misinformation on social media about birds and 5G: https://www.reuters.com/article/uk-factcheck-starlings-netherlands-idUSKCN22A3D9 https://www.reuters.com/article/factcheck-birds-5g-idUSL1N2OS1FK...

    5G US C-band launch

    I can't find the story now but I think I read that newer radio altimeters are fine and older ones aren't. If that's the case, perhaps the airline industry is seeing an opportunity to force telecom companies to pay for altimeter upgrades. That would explain everything.

    5G US C-band launch

    It looks like the FAA and wireless carriers have agreed on a staged roll out of 5G in C-band. Verizon is set to launch on January 19 and AT&T around the same time. Fifty airports will have a six-month C-band buffer zone while they figure out if the network will affect radio altimeters...

    Troubleshooting signal loss at certain times of day - C/N margin

    Solar interference occurs at the spring and autumn equinox for locations on the equator. As you move north and south from that line, the dates shift a little. For most of the United States it's in about two weeks.

    NBC On 105w

    Good question. NBC programming is, of course, free to air in the US and unencrypted on ku-band satellite. The big difference with the C-band feed is that it covers most of Central America, so hopefully it is just for content protection during the Olympics.

    NBC On 105w

    BISS is minimum-effort encryption. I would imagine most stations have equipment compatible with it. Have they encrypted for the Olympics before? I seem to remember some programmers have encrypted in the past during the Olympics because of the heavy hand of the IOC lawyers.

    4080 H - Galaxy 16 (99.2W)

    I remember them. I think it was Fox Syndication, not Fox network, and they played out the My Network feed too. Fox owns that network.

    Actuator Miscounts

    It's quite simple. Suppose you've found 121W and your ASC1 says the count is 0320. Now, bump the dish to the west until you find a peak signal from 123W. Check the ASC1 and the count is, say, 0335. So 2 degrees was covered in 15 pulses on your system. To find 125W - another 2 degrees west -...

    Smallest C-Band dish capable of receiving Intelsat 34?

    I think these footprints are for another satellite. I can see 55.5W C-band and I'm in California.

    ABC 99.0W 4120H30000

    The error correction on the ABC channels is quite low, just 9/10 I think from memory. That means if there are any glitches, any interference or the signal falls just a little the receiver has a very small margin before it loses signal. The FEC number is very important when you're trying to pull...

    Register your cband dish!

    I think I'll register mine. The mobile phone companies want to be all over this spectrum, especially in urban areas where demand is high for wireless broadband. I can imagine them being allowed access to the spectrum on the basis of not interfering with existing spectrum users. Registered...

    T90 - 90CM Multi-Feed Toroidal Ku Dish Antenna

    Where do you get those clamp parts from? I've been looking for some for my experiments with such a dish.

    CAN I????

    2-degrees is tough getting the LNBs close enough with the scalars. But, I think it depends on the feeds you are trying to pull in. If they're on strong transponders, have a nice amount of error correction (FEC 2/3 or 3/4), are DVB-S and QPSK then you can be much looser with your aim and still...

    AFN Newbie

    If you are no longer active military, DoD or State Dept., I don't think you can get an AFN decoder. At least not officially, so ensure you can get a decoder before you go to all the hassle of putting up a dish. The North East Asia beam on Koreasat 113E doesn't cover Bangkok. One possibility is...

    Intelsat and SES Propose Joint-Use of C-band by Satellite and Terrestrial Mobile Operators in the U.

    I suspect it's because once you talk about the digital divide, connecting rural communities, emergency communications and first responders, politicians are much less likely to want to raise issues. But then I'm an old cynic.

    Intelsat and SES Propose Joint-Use of C-band by Satellite and Terrestrial Mobile Operators in the U.

    That's not the the way I read it: "protect the wide array of established satellite services in the 3700-4200 MHz C-band downlink spectrum while opening a specified portion of that spectrum for terrestrial mobile use." They're talking about allowing broadband services into a portion of the 3.7...

    Intelsat and SES Propose Joint-Use of C-band by Satellite and Terrestrial Mobile Operators in the U.

    I'm not sure how this would affect us. Satellite operators clearly want their signals reliably received while mobile operators have large buckets of cash to throw at the government. I suspect any spectrum sharing rules drawn up will be aimed at preserving the link budgets used at cable operator...
