Hi all,

I recently posted about splitting broadband connection among a few WinXP-Pro machines running around the house. I have done this successfully with D-Link Wireless 802.11G equipment. When I went to RadioShack to bust their chops about my phone problem (sidenote: broke a Motorola cellular with 4 mos left on 2yr contract- RShack and Verizon claim I can't upgrade or extend plan to get a new phone at discount - I'd have to add a 2nd account with new # while still paying old one or its termination fee, OR buy a phone retail $200-$350 to activate for 3.5 mos -is this BS? I want to have a phone on my same number with the least hassle...)
Anyhow - I noticed they have sets of antennae on sale that are about twice the length of the ones packaged with my equipment that claim to increase the distance of the signal and/or its strength over the same distance as the prefab antennae. It was like $30/pair. I am not really in need of that but am curious - does it really make a difference, or is this just a marketing gimmic?

-Chris

Usually manufacturers will ship their access points with 2 dBi antennas.

You can see a fairly good boost by replacing them with some good quality 6, 8, or 10 dBi antennas. From my own experience I got a pair of 6 dBi antennas to replace the built in antenna on my WiFi card and I can see APs that I couldn't reach with the card's built in antenna.

However I'd avoid Radio Shack like the clap and get the antennas from a company that can actually give you intelligent answers on the products they sell.

Here's a few I'd recommend:

Also you can use this table to calculate your output power (AP transmitter power & antenna dBi):

curious...The larger antenna transmitting MORE output power doesn't require more INPUT power? and if it does, are there (or can there be) any issues with the power supplies that come with the devices?

It's NOT MORE output power. The antenna has a HIGHER GAIN then the stock antennas that came with his unit, and don't require more INPUT POWER to boost the gain.
