Looking for outdoor omni "whip" antenna for 2.4 GHz.

Is there any reason to not go for the greatest gain antenna, given that cost
is not too important (within reason)?

There are scads of these on the 'net. I'm looking for someone who has
experience with one or more of them and can make a recommendation for one.

Thanks,

Hi, not actually 2.4 Gig WiFi but cellular wireless modem card. I
bought one of the small verticals with a magnet mount and cabling for
about $15 ppd as I recall. My situation is that my house is built with
concrete/rebar construction, metal 'persiana' windows and screens and
its hard to get a signal out of here even on the various cellular bands.
I think the highest band there is 1.8 GHz.

I didn't go for gain since the path to the site is only about 1.3 miles
away so I opted for the little guy, about 7 inches tall, that just sits
on the roof. On the other hand, a friend in a different location got
himself into all sorts of problems with reflections and multiple tower
sites and is now looking for a directional antenna to minimize the clutter.

Another consideration is the vertical angle between you and the site.
The "high gain" verticals (I've seen ones claiming 14db) have a rather
flattened omni pattern so that if you have to look upwards to your
intended site you might find the gain to be considerably less, if any.
