For a long time I've been toying with the idea of creating an antenna array.
Although my initial idea wasn't for a satellite dish array I don't see why it couldn't be applied to the satellite TV. Since 18" dishes are relatively easy to find I thought it would be great to setup an array of at least 4 dishes.
I know it is tricky and probably very difficult to align all dishes perfectly but it shouldn't be impossible. Also another advantage of arrays is that it is possible to control the direction of the antenna beam electronically.
If somebody is following the SETI project, instead of using one huge radio telescope like Arecibo in Puerto Rico they are planning to use an array of 350 dishes!
So my question is: if anybody has tried that please share your experience.

Thanks :cool:

The only thing is that a diseqc switch will eliminate the signal from all the antennas but one which isn't desirable for an antenna array.
What I want is not to switch between antennas but to be able to add the signals from all the antennas so it would have a
better gain than a single antenna. See picture, hopefully that would make it clearer.

I think just about everyone here does that already to an extent. You use a diseqc switch not a splitter to feed 4 antennas to one receiver. I run 3 into my Pansat 330a using a diseqc with 4 inputs.
That's still not quite what nasko has in mind. He simply means a "4 eyes are better than one" approach when each individual eye is not quite big enough to see the object by itself. It's a complementary use of multiple dishes rather than the usual supplementary approach. Take 4 18" dishes, point all of them at one satellite, and somehow tie them together (i.e. a simple high frequency splitter) to hopefully combine all 4 weak strengths into one stronger signal strength.

I'm not sure that will work though for a couple reasons. With Ku (FSS) being slightly lower frequencies than DBS, the antenna (reflector) needs to be a certain size to match the wavelength. I don't know if 18" cuts it or not. As for the fact that they are lower power (another reason for the larger dish), and the real issue he's asking about, I'm not sure a splitter combining the 4 inputs will really combine all the input signal sources together to boost them to an acceptable level. You may be right nasko, some evil math may need to be done. But I'm a little skeptical.

Tux,
Thanks for helping me clear my point.
The question is not if it's possible to be done but how to do it in home environment. I was reading for one of the satellites that it uses just that kind of antenna type.

Here is the frequency spec for the 18" dish taken from Winegard's web site

Frequency range 10.95-12.75 GHz
(the same as the 30" one)

http://www.winegard.com/home/46cm.htm
http://www.winegard.com/home/76cm.htm
Cascade
An array of passive antennas for frequencies up to 1Ghz is workable and not too difficult to design.
When you're talking about taking 4 LNBs (Each with their own active components) and tying them together electrically to work as one, you're way out of the league of home experimentation.

Although technically it could be done, it's not worth it for what you're trying to achieve.

On the other hand, if you're thinking of using one LNB and having 4 parabola pointing toward it, you'll beed to find an LNB with the proper characteristics.

Nah, Anything down to frequencies as low as human speech can be reflected by an 18" dish, the only reason an FSS needs a bigger reflector than a DBS is for lower power and polarity.

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....

Continuing the Kilauea thread in the Pub here. Perhaps the Iceland one too next time there's remarkable activity.

Currently there is precursory lava flowing into the crater, leading to the next episode that'll probably start within the next day.

You can see the pace of inflation / deflation here. It serves as the primary predictor for when the expect the eruptions, which coincide w/ inflation turning into significant deflation and last for several hours on average with significant fountaining.

Oooo, quite the show now. All three vents have doming and overflows. The cone that built up around the North vent lost its upper quarter at 02:50 Oct 17 and is now spewing lava at a healthy rate. Don't know if I would say it's a fountain, but it's close.

edit: The USGS has called the official start of Episode 55 as starting at 03:19 HST Oct 17, 2026:

Alert Level: WATCH, Color Code: ORANGE 2026-10-17 13:43:56 UTC
HVO/USGS Volcanic Activity Notice

Volcano: Kilauea (VNUM #332010)

Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Issued: Saturday, October 17, 2026, 3:43 AM HST
Source: Hawaiian Volcano Observatory
Notice Number: 2026/H488
Location: N 19 deg 25 min W 155 deg 17 min
Elevation: 4091 ft (1247 m)
Area: Hawaii

Summary: Episode 55 of the ongoing Halemaʻumaʻu eruption began at 3:19 AM HST on October 17, 2026.

Volcanic Activity:
Episode 55 of lava fountaining in Halemaʻumaʻu began at the summit of Kīlauea began at 3:19 AM HST on October 17, 2026.

Fountain heights are relatively low at about 100-150 feet (30-45 m), and it is not clear whether this episode will evolve to the same heights as previous episodes. Continuous overflows from the vents began yesterday, October 16, just before 6 a.m. HST and transitioned into episode 55 fountains at 3:19 a.m. HST this morning. The current forecast is for winds are blowing from the north-northeast direction, which suggests that volcanic gas emissions and volcanic material may be distributed to the south-southwest direction from Halemaʻumaʻu.
  • All eruptive vents and lava flows are confined to Halemaʻumaʻu crater within Hawaiʻi Volcanoes National Park. Tephra fall from volcanic ash clouds is greatest within 3 miles (5 km) of the vents, lighter ash and Pele's Hair may stay suspended for large distances from the vents.

Kīlauea seems to be returning to the "normal" eruption script, impressive fountaining from the North Vent. For once, the V2 Cam has the best overall shot:

The lava flows have covered a good portion of the Halemaʻumaʻu crater floor.

Since it was already "paid" for, I spent the two hours of my time watching the John Cena action movie on Apple TV, "Matchbox The Movie" even though the reviews were brutal. It was better than I expected, so I didn't feel like I had wasted an afternoon watching it. But it felt like another "Reacher"/"Neghley"/"Mission: Impossible"/"Fast & Furious" crash and blow stuff up with lots of automatic gunfire mixed in movie featuring covert CIA operatives.

I don't think we'll get a follow-up movie from this. I expect Mattel will have other toy lines to exploit.

They run Owens at $3.99 for lb and $7.99 a couple times a month at some grocery stores here, I actually was wrong, just checked a pork sirloin roast it was $1.99 a lb. (cooked it yesterday so pack was in trash)

I also heard that someone was leaving the show at the end of this season. Any guesses as to who thats going to be?

I don't think Tim and Tony are that far apart in Age ...

Remember what Tony said to Tim when they first got back together ...
Tony said: I am the New Tony, Tim .... (something to that effect)

Tony has changed, he's been running his Security Business ... I'm sure he has grown up.

Give it time ... your judging the New Tony from the old Tony.

It sounds like Tim won't be around the Team much longer either.
