WRT54GS and external antenna...

Hi,

I need to use a Linksys WRT54GS for a wireless link of 4kms. This device
has two small antennas.

How do I unscrew / unmount these original antennas and to which connector do
I connect my external 24dBi grid antenna?

Thanks for tips on this issue

best regards

They just unscrew, but one of mine is stuck! There is a large black
piece that covers the actual screw in piece but the alrge black
covering is hard plastic and does not get out of the way. Grab the
largest part(biggest around) of the antenna and try to unscrew it. One
of mine came off but as I said I cannot get the other one off.

The "large part" can be pulled off.

OK,
thanks for that info, but what about connecting ONE external antenna to TWO
antenna connectors? How do I get full power out / in to the external
antenna from this router??

You don't...
There is a splitter inside that splits the output from the transmitter to
the two antennas. You can either combine em back together, or open the unit
up and bypass the splitter.

OK, thanks for this info. How much (in dB) do I loose if I use an external
combiner and where do I get a suitable such device?

Thanks again for tips

Don't know where to get one... I have seen external antenna packs that have
two antennas and go to both on the unit, and have opened my unit up to make
it just one output, I was told that you can't have an impedence mismatch
between the two outputs past the splitter, and there are two of em to
balance things out and cut down dead spots.. Since I wanted to use an
external antenna, I just tapped into the output before the splitter.

Thanks for this info. Since you have 'been there and done that'::

What kind of connection is used between the sender and the splitter. Is it
soldered or some kind of coax plug which can be 'cleanly' connected to a
pigtail cable?

It was soldered.. I just added a mini-uhf thru the case connector, cut the
lead and soldered it to the new output connector.

somewhere on the internet are pictures of the inside of the device... I
don't happen to recall the links (maybe someone here knows em, or a search
can find em).. Amazing... since the advent of digital cameras there seems to
be a plethora of people doing autopsies on things and posting the photos....

PS In case you are curious, they don't bleed when you cut em

These are diversity antennas - which means the one with the better signal
will be used fro client - but not both at the same time.

I disconnected both, and connected a new antenna just to one - it works
fine.

In the admin pages - you can control the config of the antennas.

Go get the Linksys documentation form their web site for more info...
