Antenna for Linksys WAP-11

I'm looking to extend the range of the Linksys Wireless Access Point (WAP-11) I bought. I'd like to purchase a Yagi-type indoor antenna to add, say, 50% more range, but I'm puzzled by:

1. The choices of 2.4 ghz antennas (which one?)

2. The type of connectors at the WAP end and at the antenna end

3. The fact that the Linksys WAP-11 uses TWO dipole antennas (does this mean I have to buy two yagi antennas, or one?)

4. Is it worth it?

Thanks.

Firstly I have never seen one of the antennas for wireless but from your description I would think that the 2 dipoles that are being used are connected by a phaseing line that makes it very directonal. Have you been able to find a yagi antenna for the frequency involved? Considering the wavelength involved I would think it would be very difficult to construct a yagi this size except for maybe one etched on a circuit board. Unless you had at least a 5 element yagi it probably would not be much more effective than the phased dipoles that I think you have. You do not gain any more power with the antenna you just narrow the direction of the transmitted sig. One other thing constructing the Gamma match for these frequencies is very very difficult.
Hope this gives you a little insite into your question.

Well, yeah, there are yagi 2.4 ghz antennas for single dipole units manufactured by smc, addtron, avaya, and other 802.11b WAP units. This particular one uses the two dipoles. My question deals primarily with the two dipole antennas. Are you saying that I don't gain coverage with a larger antenna? Other WAPs with less coverage areas than the Linksys WAP-11 have them (larger antenna options).

Am I missing something here?

BTW, thanks for the response.
 
AS you can tell by my previous post that I know nothing about the antennas that you are talking about but I have some general knowledge of antennas. What I was saying is that when you read the term "Gain" in the specs of the antenna it relates only to the narrowing of the cone of the signal transmitted from the antenna or in other words it makes it more directional, or concentrated like the beam of a flashlight. When this happens is you gain signal strength in that the signal is not spread out, in this case horizontaly. The term "Gain" means the directional concentrating of a signal over a dipole in free space radiating in a bidirectional way. Also the gain of Phased dipoles are very good and have a very good gain if it is well designed and I think that it would take at least a Yagi with 3 directors and 1 reflector to = the gain of the phased dipoles. I think that if you will look at the specs of the Yagi's that are being offered this will give you some basis for considering the purchase of this antenna. One other thing regarding your question 1 or 2 yagi's if you buy 2 yagi's you will have to get some kind of phasing line to stack them, the gain from stacked yagi's is really dependent on how they are connected. You would only have to get one to replace what you have.

Zoom Telephonics makes a variety of antennas to extend the range of their ZoomAir Wireless product line. I dont know if they will work with the Linksys or not.
This link gives product specs: ZoomAir
 
As you can see here:

There is a big variation in distance. Moving the Antenna to the best location, can make a big difference even without gain in transmission input.

The zoom antennas look good. I just wonder if physically they fit non-zoom equipment (in my case a SMC system)???

BTW: Log to BUY.COM, and do a search for Antenna.

You will find a lot of entries, but most seem to be brand connected.
