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?
