5.5dBi-gain antennas @ Radio Shack

Radio Shack is now carrying the following:

Designed for use with Linksys® Wireless Routers, these 5.5dBi-gain 2.4GHz
Router Range-Extender Antennae are used to extend the range of indoor access
points or client bridges in 2.4GHz wireless LAN environments. Most standard
antennas supplied with indoor equipment are only 2.2dBi gain! The 5.5dBi
more than doubles the signal strength to give more range. The antenna
features a 360° horizontal transmission pattern and a 50° vertical
transmission pattern.

CAT # 278-844 $29.99/pair

As with all the garbage Radio Shack sells, this is just another overpriced
item that they are peddling. You won't see any performance gains over the
factory supplied models.

The antenna that comes with you kit is most likely about 1-2 dBi, certainly
doubt if its 5.5dBi.
You could make a good omni antenna yourself from scrap RG58 coax sections.
Its the number of radiators that is one of the things that determins gain,
so if its a longer antenna chances are its got a better gain because its
made from multiple radiators.
Something like this:
|
|||
|
|||
|
|||
|
|||

4 element omni
| = radiator (wire with no shield)
||| = waveguide (wire shielded by a copper screen)

You really only need one good gain antenna, two is for if you are using
diversity but you should be able to select left or right antenna and get the
same range.

Note: the elements (waveguides and radiators - think thats the right terms
but could be wrong) are a wave length - 123 mm for mid-band on 2.44 ghz
wavelength=speed of light/frequency
300,000,000ms/2,440,000,000hz = 0.12295m
So thats 123mm.

Not sure about the speed of light through copper, gravity has an effect as
well but thats another story.

Why do you say that? Do you have anything to back it up or is this just a
slam at Radio Shack?

I (for one) find no credibility in your assertion unless you back up your
statement. I'm quite familiar with many antenna sources on the Internet and
I'm not aware of anyplace where you can buy two 5.5 dBi antennas with RP-TNC
connectors for $15.

To each his own. Go out and buy a set and enjoy them, but don't come here
crying when you realize that you find them to be a waste of money. If you
didn't find a place that sells a pair with RP-TNC or RP-SMA for $15 don't
blame me.

I take that to mean you can't find it either. So you can't back up your
statement. Didn't think so.

Don W.

Don't let the specs mislead you. Double the dB rating does not mean you
will double your distance. But it will increase your signal strength.
Simple enough to try! I'm considering adding a pair of these off the back
of my Linksys WSB24. They are about twice the length of the stock ones.

Don't let Rita's comments discourage you...she has antenna envy!
