RE: Connecting two antenna's togeter

Hello,

The title of this thread does not really descript what i am doing.

What i want to so is put a PCI card inside my plexiglass case, but extend the antenna connecter to the outside of the case so that i can just screw the external antenna to the case and not directly to the PCI card.

The picture kind of explains it

what kind of connector? SMC, N, BNC? What card is it? Do you already have a pigtail? do you already have an antenna?

Its a Microsoft PCI G adapter model number MN-730
and no i don't have the antenna yet?

For your application, your best bet is to buy an adapter for your card that will adapt from your cards connector to something more standard. For instance for a d-link you would buy an RP-SMA to BNC, or to F, or to PL259, or to N. Then you can bet a feed through barrel connector and mount it on your case. Most external 2.4 GHz antennas seem to have N connectors on them so that might be a good choice for your converstion. Keep in mind that every connection introduces loss into the system. 1db is the standard approximation per connection (therefore your barrel creates 2db loss). Also, at 2.4 GHz, there is an extremely high loss per foot through your line. Larger line creates less loss. Just keep all this in mind when running your cables. If your not careful you can quickly loose all the gain you are attempting to add by moving the antenna and upgrading it.
