Aerialix makes some nice products, but why in hell would you want to use a base antenna on a vehicle? Especially when you consider that there are many fine antennae out there designed specifically for vehicles.

And as we all know, looking good is half the battle when dealing with RF.

I would go with one of these:

5 dBi Magnetic Mount Omni Antenna
Compact Black 7.4dBi Omni Antenna w/ Spring Base

Thorn: why the hell not? An omni is an omni, and this one has the mounting setup and looks that im after.

Allow me to clarify my question. I am asking if anyone has had experience with how well this antenna works? This is obviously my first consideration. I know the antenna looks good, what i dont know is how well it works.

My car currently only has one antenna (UHF CB) as shown in the picture. I would like to mount my wifi antenna in a similar fashion. I realise that the 5dbi magnetic mount from fab-corp is one of the better solutions available at the moment, but magnetic mounts are a temporary solution and are of no interest to me. The ground plane on these also means i cant mount the antenna where i want to..

So.... has anyone actually had experience with this antenna?

Well sort of. An omni designed for mobile use is for the most part designed for mobile use. An omni designed for base station use is (you guessed it) mostly designed for base station (fixed) use. Base station antennas are not designed for the vibration associated with mobile use.

Bull. An omni is not an omni.

RF design (frequency and patterns) in relation to the application (mobile or fixed) should be the primary consideration. Looks should be the last criteria for choosing an antenna. You wouldn't buy a car based soley on the color, would you?

As wrzwaldo said, you should be getting one designed to be used in a mobile. In addtion to what he noted about vibration, the ground plane design also is different. If you want a permanent mount, then you should look for one. They are certainly availalbe.

Bottom line, a base omni may work, but it won't work as well as a mobile designed for the task.

thorn: are you able to elaborate any further on this comment?

An omni is designed to radiate evenly in all directions in the H plane. Whether the omni is designed to be fixed or mobile, its radiation pattern is going to be the same omni-directional pattern is it not?

And when you say frequency, both antennas should be tuned to a center frequency in the middle of the 802.11 spectrum. How is the "frequency" different between a mobile and base antenna? Are you saying some account is taken for doppler shift in the mobile antenna? If so then what happens when the car is parked?

How is the ground plane design different? All antennas need a ground plane, mobile or base type. If you look at the suggested mounting options for the antenna you can see that their suggested bracket is very similar to the way i want to mount hte antenna on my car.
http://www.aerialix.com/antenna/arlx-ommnt_item.html

wrzwaldo: thats a good point about vibration. However a base station antenna can also be subject to high wind and vibration, although obviously not as often as one mounted to a car. I think a well built base antenna would last fine, especially when its only 8" long. I will definately take your point into consideration though

And as for the comments about looks: i take a lot of pride in the appearance of my car. I will not be mounting an antenna that looks ridiculous. Looks are not my primary concern, however there are limits as to how ugly i am willing to go....

thanks for the comments, the help is appreciated

Sure, they are designed to radiate in a circular pattern in the H plane. However, the thing that is important here is the ground plane. Mobile antennae are designed to be used in conjunction with metal car body. Base antennae are not.

As to frequency, that was a general statement concerning the selection criteria.
