Wifi n00b cable questions

I just purchased my first USB wireless adapter, i think its an importer520, it has a detachable antenna and i would imagine the connection is SMA?

I am thinking about purchasing an outdoor antenna to put on my roof. If i do this i will need about 40 feet of cable. I understand the lowloss SMA cable is pretty expensive.

Since my wireless adapter is usb, I was wondering if i could use the phone line instead of buying the SMA cable. Running USB through phone lines can be seen here youtube/watch?v=j9Olbn02X3s (It wont let me post URLS!) You can go pretty far with these, but I was wondering if i will have a larger loss in signal/strength by doing this rather than SMA cable.

Any input would be great!

This season's most popular Ugg Boot is the Bailey Button Triplet. These boots will fly off the shelves once the first snowflake of the year hit the ground. We have talked with dozens of retailers about how popular Ugg Boots are.
Everyone that's bought Ugg boots will tell you to buy them early, since they always run short in supply by the time the cold hits in December. At that time, you will probably be looking at your 2nd, 3rd, or even 4th choice, - if you can even find it in the size you wear. The reason being is that Ugg has strict control over the amount that they distribute, so that they can maintain a high demand.
This online store that I recommend carries Ugg classic boots in all sizes - and the best thing is, they offer free shipping when order over 100 USD ,the boots are fantastic.to know more about the supply ,you can kindly visit

pardon me for coming across as a pompous crabby old know it all, but - dude, you don't have a clue.

SMA is a connector, not a cable

the connector used in wifi is RP-SMA.

running 2.4 gHz RF through phone lines is impossible.

USB has 5 VDC at 100 mA available. there isn't enough DC power available to generate interesting amounts of RF power. USB adapters are for connecting to an AP you can see in the same room
