Antennas are passive devices. A higher gain antenna does not "Draw" more power from the radio. A higher gain antenna worksits magic by directingthe same amount of energy produced by the radio onto a smaller area.
as a reflector with a light bulb focuses the light in fewer directions than a free standing bulb.

 Thanks for all the replies. It was my understanding that antennas were passive as well. However since the USB "modem" transmits I thought there may be a minimum power output required for the antenna.

What am I trying to do?
I have a USB wireless broadband modem from alltel. It is a UB150. It has a Y USB connector to increase power to the device and does something for the RF. It does have an external anntena adapter, the end that attaches to the anntena appears to be a female F fitting, not really sure.

I need an anntena to increase my speed. My average speed as is, is about 700 Kb/s down and about 130 Kb/s up. If I get close to the tower, several hundred yards I can get speeds of 1800 Kb/s, even though they claim 2.5 Kb/s on a EVDO net.

I would like to increase my speed with an anntena. My father would like to utilize the same service as we cannot get any type of broadband. We are unable to recieve any useful signal there. So I need to get the highest gain I can get to test at his house as well.

I know this post was long, sorry. I hope I explained what I am trying to do enough. Any product suggestions or explanations would be appreciated.
