New to wifi.....Making a WIFI biquad and hook up

I am wanting to try and make my own biquad wifi antenna. I kinda figured how to make it and how to hook the pig tail to antenna, also I also understand how to hook up to a 400 cable to and from antenna. What I dont understand, is how to connect the cable to the router i am looking at a WRT54G for my router. I read that a RP-TNC to N Male Pigtail is recomended for connection to the router, but I am presuming that I will eventually need to go into the WAN port...... any help would be appreciated. Also If making the biquad is a bit advanced what pre made antenna out there could be used?

Did you ever figure out the final hookup? I have the same problem.

I've got the dish, the antenna and the wrtg54g (with DD-WRT). But I still need final details such as:

1. does the pigtail plug into the "internet" port on the router? Seems obvious that it should, but not sure.
2. do I then connect via ethernet cable the router to my pc?
3. do I configure router any other way than just making it a "client"

Antennas transmit, and intercept, Radio Frequencies; RF.

You can put an RP-TNC connector on the pigtail from the biquad and skip the N connector. No need for additional connectors.

The antenna connects to the RP-TNC connectors on the router.

The WAN , AKA Internet connector takes the CAT5 cable from a DSL modem or Cable modem. It has a separate connector because it has a firewall between it and the other four LAN ports on your router. The wireless connection on an AP is on the same side of the firewall as the LAN ports.

If you have installed third party firmware on your router, making it a client, you are using the wireless side to connect to the internet. The wireless side connects directly to the LAN ports, so no firewall.

Not possible to tell you how to configure, since you didn't specify how your Linksys became a client. If you used DD-WRT, Google;

DD-WRT Client
DD-WRT Client Bridge
