If you are referring to my post that is not what I said. I said

1 antenna is TX/RX and the other is RX only.

ie 1 tx and 2 rx

As in only one antenna transmits and both receive, ie receive diversity.

Is that the case with all cards??? I know on a linksys card that I modded there was no TX on antenna 2 and the connector/test point was on antenna 1.

Thanks for the reply wrzwaldo and skizziks.

Ok, so even if the rx and the tx/rx antennas are not connected to the radio at the same time, that still leaves me with the hirose connector on one of them and the solder pads on the other, im yet to see which one's which.

Can i just connect the coax to the trace that goes into the hiose connector and the sheild to the ground i assume that the 4 pads are identical and i can use any of them for ground ?? ya ?? ney ??

Hey guys,

Just ordered some pigtails and a 16dBi Yagi, will let you know how the netgear goes with that.

Too bad that Fry's Outpost ran out of the 108G Airlink USB keys i ordered, that would have been good.

Anyways, have a nice day everyone,

Cheers,

Question was, i have red somewhere that only one aerial is used for both reception and sending, question is which one ??? is there a standard ???

I mean, correct me if im wrong but i thought that one aerial is used for both rx/tx and the other tx (maybe its the other way around 2 recieving one sending)

So would that mean that if an aerial is connected to an rx end only would that pretty much kill the performance ???

Edit: Typo

The easiest test I've found is to cut the trace to one of the antennas. If the link goes to shit, then you've got the right one.
As others have suggested start with the antenna with the test jack.

Cut the trace, that's a bit extreme.

Theres a little cap on each aerial, i have taken the one off the aerial with no connector and its still working.

So i'll assume that the aerial with the connector is the right one, but i'll double check anyways.

Can't wait for that Yagi to arrive, so far im picking up 4 AP's from my living room with no additional aerials, we'll see what the extra aerial will do.

hi polski, do you have any update on antenna modding for wg511t?

Hi p0lski, I have the same card, the one with angulated patches, im also looking for ext antenna mod, have u solved the trouble? I found a guy who used the antenna w/o connector, look here: http://photobucket.com/albums/y288/hybridchemistry/cantenna%20wifi%20card%20hack/ .... but I don't know if it works.

73,

I think it's really logical what I don't remember who said about cutting the trace on one of the aerials and check if the signal suddenly drops...
what I need to know is what's the use of this ceramic surface mount capcitors I mean what are they used for ? on most of the antennas on pcb

They provide ac coupling/dc blocking.

Scruge thanks for the reference, ok I think I got a rough idea about the use of these capacitors correct me If I'm wrong they're basically used to avoid any short circuit when hotplugging and placing some kind of potential differnece and damaging maybe the RF chipset or any other Ic component.
There's not much use of the caps as far as it comprehends RF radiation on the surface mounted antenna traces

Hey guys,

Iam also in the process of doing this antenna mod to my wg511t.


I came across this pigtail

http://cgi.ebay.ca/I-PAX-HIROSE-U-FL...ayphotohosting

And also this antenna

http://cgi.ebay.com.au/7dBi-HIGH-GAI...QQcmdZViewItem

What i need to know is, can it be done?
And what exactly do i have to do?

Pretty much i would solder the pigtail onto the hirose, and plug the antenna into the other end of the pigtail... corrrect? or is there more to it?
I just want to boost my signal when war driving etc.

Please go up to the welcome desk and read the posts there. Posting a duplicate post is usually frowned upon. Having your original post go into the newbie bin should have told you something.

Please use the search button and do some research on your own first, and if you still don't understand what needs to be done, THEN ask a specific question.

ok sorry mate, yeah i thought it was wierd that my post moved to another thread.

I have actaully spent around 2 hours searching for other info, on this mod. So before you go off at me for not doing my research, you should at least ask me if i allready have..

For this mod, i havent seen anyone successfully complete a fully working one. I was just asking for someones professional advice, if the pigtail and antenna would be compatable with my netgear wg511t card. If thats the case, i will go ahead and buy those 2 items of ebay, and go from there.

IF your card has a Hirose connector and IF you obtain a pigtail with a matching connector, then it is a matter of merely plugging the connector on the pigtail into the card, plugging the pigtail into a transmission line and then plugging the transmission line into the antenna.

/waiting for the inevitable post : "Where can I buy a transmission line ? Which model of transmission line would fit the above antenna and pigtail ? I can't find anybody on E-bay that sells it..."
