Here are some types for antenna cable and connectors. Deliverers here are Elfa Ab and Farnell Components .
Evere part must have impedance of 50 ohm. The impedance of coaxial cable depends of ratio D/d where D is inner dia of the shield tube and d is dia of inner wire. The ratio is about 2.4 in the 50 ohm air insulated coaxial. Other insulate materials decreases the ratio with so called velocity factor.
A = N panel socket in the Antenna, type Radiall R161 404 000W.
Elfa item 46-105-23, Farnell 310-025
B = N plug suitable for about 10 mm dia cable like H1000, same connector
as for cables RG9 and RG214.
Elfa item 46-075-11, Farnell 309-989 or 143-784
C = Cable Belden H1000, low loss and semirigid, diameter 10.3 mm.
Elfa item 55-914-25
D = N cable socket for 10 mm cable. Elfa item 46-086-00, Farnell
310-013 or 143-786
E = Adapter cable 50 cm long with N plug and a connector suitable
for the wlan card.. The Orinoco card there is their private connector which
is not sold separately. Whole Orinoco adapter cable is sold in wlan deliverers.
Most other wlan cards have standard connectors as SMA, SMB, SMC or MCX.
