Hi,

I have a WTR54G Linksys Router. I tried getting an external outdoor antenna for it, however it didnt fit inot the router. What make of antenna will fit this model?

I also want to create another wifi network amongs friends in my area. Its quite hilly and alot of trees. What would be the best antenna combo from your experiences. I also have an old DSTV satalite dish. I read on the net, how users took their old dish and converted it into wifi antennas. Will it work?

the antenna normally have the n-type female connector on it. the linksys has a TNC connector on it, so you just need to get the cable for it. The antenna does not fit on to the router, its connected via a lmr195 or lmr400 cable.
I am not so sure about the dish but if you want to try and let us know :p

:mad: Trees and hills:mad: , what range are you looking at and do you have line of sight?
 
yea, you probably need to buy the patch cable to go between the router and the aerial!
 
cranus - mufasa and bboy are right. you need a "pigtail" TNC to N-Type connectors to convert the connection on the antenna port of the wrt to connect to the antenna.

what area are you in maybe someone can point you to a place that can supply it.

trees, hills and building are bad. so no LOS no connection. one of the most difficult parts of 802.11 i think.

You can get a "feed" for a dish like this one - http://www.miro.co.za/stage/intranet/datasheet.php?id=209

it has been said that you can put a usb wifi device at the focal point of the dish it works well.... i have not tried maybe Rodent can advise on that one.

If you got a spare dish lying around not a bad plan to use it.

suggest you go to http://www.jawug.za.net and broswe their site... it should asnswer most questions you have.
 
As far as I know, the connector on the back of a Linksys WRT54G is an RP-TNC
(Reverse Polarity)

Uniterm direct and Miro can supply an RP-TNC to N-Type Convertor - or the individual connectors if necessary.
 
Re wifi router + antenna

ok thanks for the info.. cleared up some issues.

1 more thing i forgot to ask about the wrt54g, there are 2 antennas. If I not mistaken 1 is for Tx and the other is for Rx. Do I need to change both, therefore 2 outdoor antennas or just 1 of them,.

I gona do more research on the dish and see what I can come up with. What I gather you just need to change the focal point. In most cases people were using a tin can for the focal point in america.

My fear is that i invest in antennas etc and the dam thing doesnt work. :p
What I was thinking of at the receiving side is to put another antenna.

Go check out http://trevormarshall.com/biquad.htm for details on constructing a feed for your satalite dish.
 
cranus - the wrt only has one radio therefore you only need one antenna.

"What I was thinking of at the receiving side is to put another antenna."
you got the idea... for the best link you wouls rather have an antenna of equal gain on both sides... eg 12db---12db rather then 2db---22db
makes a more stable like. the poynting feeds are made for the DSTV dishes AFAIK. so give them a go... and a dish is VERY directional
 
Eben - call me lazy but it looks like it would be a damn load easier to go buy a already made feed that will work first time for R200.

So i can remove both antennas and just insert the new high gain into the primary slot?

I havent yet upgraded any firmware so I can't yet configure the antenna diversity to primary.
 
"So i can remove both antennas and just insert the new high gain into the primary slot?"

cranus - correct, can't remember with the linksys firmware if you can set the antenna but i know that most of the other firmware allows you to use whichever antenna port you want.
 
but which is left and which is right???
is it from looking from the back or the front of the unit?
and i only have 1 antenna plugged in so i thought i would work it out be trying each side and seeing which one didn'twork, but it made no difference anyway!
 
bboy - if you left the firmware on auto for the antenna it picks which has better signal and uses it.
I think A is next to power and B the other
 
The Antenna should connected to the connector next to the the power jack (Antenna B) and the firmware should be configured accordingly.
 
I find the B or left antenna has the least noise. I did a small test once.

Yeah, that makes more sense but i still like experimenting. I've built a couple of biquads without using a dish for short distances (1-2kms) that actually works quite nice. The first one took me about a day but once you've made the proto, it will take you about 30mins.
