Alternative Uses For an Old Satellite Dish?

kdawson posted more than 5 years ago | from the birdbath-for-condors dept.

Communications 552

ya really writes "My family has one of those BUDs (Big Ugly Dishes) sitting in their back yard still. The other day they asked me if I would take it apart for them. Aside from simply recycling it, I was wondering if there are any alternatives for its use. It was one of the last made before DirectTV and Dish took over satellite broadcasting, and even has a digital receiver. I'd say it was made around 1996."

AlienIntelligence (1184493) | more than 5 years ago | (#24206675)

Literally.

We had an old 8ft dish. My dad and I covered
the mounting holes with stainless mesh, filled
it with good soil and compost and planted a
nice selection of butterfly/hummingbird flowers
in it.

This kept certain plants from roaming beyond
the area desired. Use plants that trellis or
hang to cover the ugly sides/underside.

That oversized planter has been going for over
a decade now. The plants do a good job of
reseeding every year.

Obvious Answer: Wi-Fi Antenna (5, Informative)

slifox (605302) | more than 5 years ago | (#24206425)

Satellite dishes make excellent directional 802.11 antennas.
Just remove the existing LNB from the dish and replace it with a homemade antenna, like a biquad, tuned for your band-of-interest (i.e. 2.4GHz ISM for wi-fi). Make sure you get a powerful (high RX sensitivity & high TX power) wireless card with an external antenna jack

Here is one project write-up, though I'm sure there are many others:
http://www.engadget.com/2005/11/15/how-to-build-a-wifi-biquad-dish-antenna/ [engadget.com]

Alternatively, keep the LNB, get a DVB capture card (PCI models go for $20-$80+ new), and use the dish to get FTA (free to air) satellite TV.
There are many communities for this kind of thing exactly, just search google for: FTA forum

I'd also take apart that digital receiver and reverse engineer the hardware as much as I could, just for kicks.
When you've gotten your hour of fun out of it, gut it for parts and move on to the next interesting project.

Some lads with a couple of your dishes cracked 125 miles [boingboing.net] during the 2005 Defcon Wi-fi distance shoot out. With your one dish on one end, and even the weakest built-in wifi antenna on the other, you can still create a solid network connection to the next County. If the other antenna is a run of the mill 15 or 24 dB directional wifi, you can really crank.

Solar Furnace FTW, (0)

Anonymous Coward | more than 5 years ago | (#24206525)

just give it a mirror finish. You can do this even with aluminium foil and you'll get a pretty powerful hotspot, but gluing lots of little mirrors to cover the surface (a bit like a disco ball) will work better. A curved mirror finish will work better again, but can be quite difficult to achieve

Re:Solar Furnace FTW, (1)

Var1abl3 (1021413) | more than 5 years ago | (#24206929)

I was thinking the same thing. I remember reading about some guy who took a bunch of the disco ball mirrors and glued them to the dish and put a steam generator (coil of copper pipe basically) where the antenna was. He used the pressure to drive a steam turbine or engine and got a few KW of power, as long as the sun was shining and he continued to "steer" the dish to point at the sun all day. If I remember correctly he used a fluid that evaporated at a lower temp than water to help get more power from the heat.... but that was a while back and I have a memory leakage issue. Or do what we did and bury it for the base of a fountain/water feature. It made for a nice round dish to put the fountain in the middle of, but ours was an old solid style and not the mesh kind. Good luck!

Mmm, true that. That was actually one of my favorite things about having one of those huge old dishes. We were able to capture some of our local news company's feeds.

Those old big dishes are a great way to get into Moonbounce, aka EME (Earth-Moon-Earth). Bouncing signals off the moon to communicate is way neat. You can also bounce you signal off the moon and listen to your echo. The challenge e these days is to get a signal to the other station with as little power as possible, with some operators having contacts with as little as 100 watts.

thermal collector (5, Interesting)

Anonymous Admin (304403) | more than 5 years ago | (#24206935)

Yank out the transceiver, put in a heat exchanger in its place. Use sheets of 1/2 " peel and stick mirror tiles to cover the dish surface. Pick up a small 4 sided pyramid, put photocells on all 4 sides, and use a couple of differential op-amps to determine which side has the most light hitting it.
Use those two signals to run the motor controls to aim the dish. It will always point at the brightest spot in the sky. A small pump feeding fluid (such as connonseed oil) thru the heat exchanger, to a large thermal well( say a buried concrete container full of steel slugs), will gather all the heat you need. Use the secondary loop from the thermal well for your home heating, hot water, cooking. etc. (cottonseed oil will easily heat to 400F)

C-Band is still in fairly active use in the US and around the world -- you could (gasp!) use it for what it was built for. It's the only way to get truly ala carte TV service, and usually costs a lot less than the alternatives (not to mention all of the free stuff out there). You'd probably need a new receiver to get digital channels, but I've spoken with plenty of MythTV [mythtv.org] users who have C-band setups.
