wifi cables


Ok , whats the first thing to know about wifi cables & connectors is that they are 50 ohm not that both the connectors and the cables must be 50ohm yes , the connectors :)

The bad thing about wifi is that the leinght of cables is wery limited.
No more than 15-20 m that`s the maxumum ofcorse u need to use better cables + pigtails for that leinght
Ok lets start with most common things
Mos Common cable`s for wifi
are CFD-200 and CFD-400
CFD-200
CFD-200
CFD 400
CFD-400
The diffrence about these two cables is the size of copper wire
200 smaller and 400 bigger
So cfd 200 cables are used fow smaller leinghts no more than 3m and cfd400 up to 15-20 m
Most Common Connector`s used in wifi :
N connector
Rp-Sma (Reversible SMA Connector)
Tnc
F

N
Various Types Of N Connector
The n connector is the most common conector on antennas , and some ap`s physicli it is a big connector , because of that he is not mounted on PCI cards there are some solutions for mounting n connector on the pci card but hmmmmz dont like that

Rp-sma
Conectorrs heh , Its like small N connector and its most commonly used on PCI wifi cards because their`s size , that`s one of the problem when connecting the pci card to antena with N connecor because on rp sma u can only mount cfd 200 cable because of its size therfore we have pigtails (later about pigtails)
connectors
The TNC connectors are n lookalikes but smaller it is commonly used on the Linksys equpment and som others its stupid solution but heh ... i didnt make them
Ok So waht are pigtails?
Pigtals are small cables mostlu from 5cm`s to 1m and they are used with cdf200 cables.So what are they used for? lets set an eg:
U distance between ur antena and ur pci card is 5 m and on the antena u Have
N connector and on ur pci card u have Rpsma.The 5 m is way long for cfd200 (note as i said on rpsma u can only mount cfd200).So What We do we mount 5 cms of cfd200 cablen on rpsma and n connecotor from there u will make antoher cable with 2 n connectors mounting cfd400 cables to cover ur 5 m distance ... the problem is solved
