New wifi antennas

Hello

I need wifi antennas.

If my memory don't fail on me, I remember I've saw carbonfiber antennas for laptops. It was like three antennas in one cable. Anyone know anything good I can get? I'm going to use it with a 6300.

They were like 19$ each. Don't say that it makes no diffrence, I anyways need three new antennas.

Ah and they must ship internationaly. To Norway, to be spesific.

 

Im interested in this as well. These antennas offer better reception?

 

I installed 3 antennas in my laptop on my signature. It gave me a little bit better range. Before, I could not connected, well I was connetced but got no internet signal in my kitchen. Now I can surf over there. However, I gave that laptop away 2 days ago. Now I'm bulding a laptop. So I'm missing wifi antennas. But as said, the 3th antenna did not make that much that much diffrance, so I want something better this time!

 

So whats a good upgraded antenna's to buy instead of the stock ones Dell give us?

 

What wifi card do you have? I've found carbon fiber antennas a while back, but I never got'em. I used the 3th antenna from my ThinkPad that orginaly came with 3 antennas.

It gave me better range, but nothing more.

To give a example, my laptop in my signature, I get full bars in my room
I'm now on a laptop with 5100 and stock antennas, I get between 3-4 of 5 bars.

The other laptop is also picking up more wifi points, but cannot get internet even connected.

However, since I gave that laptop away, I need to make something with this. It is not a problem at the moment, but in my other house, I don't have good signal in 3th floor, which is a problem, a big problem.

 

Yep. I have seen those, it was basicly there antennas on one cable, which where thick.

Also a bit more expensive then other thin cables. Maybe the diffrence is minimal, but sometimes that is the diffrence between yes to wifi or no!

 

ok I'll say it.

makes no difference.

A 'copper' antenna cut to the proper length for a specific freq band will behave/perform EXACTLY the same as a 'carbon fiber' antenna.

It's easy to determine if a copper antenna is cut to the proper length.

How do you determine if a costly (looks to be 50X price) carbon fiber antenna is built properly?

Spend your $$ if you like, be prepared to have a whole pile of peeps laugh at you.

 

Have you ever tried those?

And there is diffrence between them, for example the antennas from my Thinkpad feels much more quality then those from my Alienware, which is ok. But why are you all so negative that. I'm of course not going to buy from a local guy in China which makes those at home...

 

emjoy.

The 'feel' of an electrical component buried inside of a case doesn't have a lot to do with it's electrical performance.

 

Ive had pretty good luck with this. Its cheap and usually doubles number of connections i can get. Just food for thought.

It seems like you guys have missunderstood. I mean internal antennas. Not external.

 

I just found these;

I wonder how they do the job. Also, FYI, I don't have any antennas for my new laptop, so I must in any case buy some. However, my Intel 6300 does have 3 outputs, I assume antennas are antennas no matter which one you plug it in on, right? (1,2 or 3)

 

An antenna will perform optimally if it is the correct length and gauge for that frequency. Making an antenna longer or shorter or with thinker wire will reduce its performance for both sending and receiving.

My father was an amateur radio operator so I learned a lot about that growing up. ( I was always the lucky one that got to climb up the tower to swap out antenna's)

For extended range I use a USB alfa wireless adapter. That sucker finds signals that the built in wifi cards do not have the power to access.

With these antennas you can switch to either an outdoor antenna or a magnet mount to use in vehicles, or just use the rubber ducky antenna that comes with it.

 

A long range usb adapter will give more range than your laptop internals by far. Alfa AWUS036NH 2000mW Best Long Range USB Wireless Adapter for 802.11N. w/Jack & Antenna

 

I see what you mean. But, agan, USB adapters are not my intrest. I need internal antennas for my laptop.

So, my question is, I don't have any at the moment, and I'm going to build my laptop back up again soon! So, I need 3 antennas. I did a search, and Tyco is a well known company, however, I did not know about them.

Is there anything other you can suggest over the antennas I linked few posts above?

 

I think the 3 connections depend on how many antennas you have. If you have just one, you connect it to MAIN, with two you connect the second to AUX. Most will have two connected with only one active at a time with the computer selecting the one with the best signal. I'm not sure about the third one, but I think you need 3 for wireless-N? That carbon fibre thing you speak of, I'm not so sure about. Having all three in one place wouldn't really give much of an advantage, if you have 3 antennae, it would be best to put one in the centre of the LCD, and the other two either side of it, seeing as you don't have any installed at the moment and would be taking it apart. Some people get decent signal just leaving the 3rd antenna (when they upgrade) next to the wifi card instead of taking the whole laptop apart, and get a better signal.

If I remember correctly (from a - level physics!) positioning also affects the signal? I.e. your orientation in regards to the router, something to do with standing waves. The two stock antennae in a laptop will most likely be aligned in different directions to compensate for the fact that you will not always be sat in the "optimum" position. Kind of why all tv aerials are similar length and point towards the same location.

 

Also, most mini pci wifi cards have the same connection so the antennae you buy will not have much variation between them, unless of course you go for a really cheap, poorly built unit.

That guy has 3 in one pack with free shipping, but then its from China which I can never be sure of. Its cheap though, maybe worth a shot?

 

Hey thank you for this post!
Well, yes, I must take my laptop apart. I also need to fit a new webcam. So, as you said, I'll place one in the middle. On my HP, I had one on each side of the screen and one on the bottom of laptop, close to RAM sticks. And, for 3th antenna there, I used the 3th one from my ThinkPad.

I contacted this seller, but no reply...

 

I would insted buy 2x those other above At least their from USA.

 

Shhh, don't spoil it!

 

A little update here:

I know this thread is old, and I never got into building the laptop at that time since I got my HP back after a few weeks. NOW, my new laptop is arriving friday, the thing is, 6300 is a must for me so again, I need a 3th antenna... As I don't want to pull another out of my Qosmio or my ThinkPad.

I'm not going to make a therad about 'which is best' this time, just going to buy a 3-pack antenna from eBay. I found a deal for 15 USD. Includes 3 antennas and the seller says that this set of antennas have "much stronger signal strength than any other internal antennas".

It is going to cost me about 20 USD, but that is nothing.. So I'm going to give it a shot.. Ah, and by the way, there is 64 sold of this item, and non negative feedback, so I think I'm on good track I'll let you know the result compared to my HP (signature) with 3 antennas, 2 orginal HP and 3th one orginal from my ThinkPad T61, shipped from ThinkPad with 3 antennas. This will most likely not be before saturday or even sunday.

 

good luck,

You gonna do any comparison?

 

Yeah, as I said in the post above. I have the laptop in my signature with the 6300 with 2 stock HP antennas and one Thinkpad antenna. I'll see how it does aginst the antennas I just ordred.

The wireless ruter is in my room, and with my HP I usually have 5 of 6 bars there. Before, 3th antenna I had 1 bar, connected but not internet. I'll go further downstairs and see how it does against this HP. But, again, it won't be before saturday or sunday
