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)?

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.

Whip antenna? What is this, for a vehicle? For a stationary location it
seems like it'd be an extremely bad idea to use an antenna that 'whipped'
around.

cost

Alligator effect. Wide mouth receiving everything. If you don't need to
pickup everything then why bother? It just makes it harder for your WiFi
router to cut through all the noise of distant stations it doesn't
communicate with. Get the right antenna suited for your installation, no
more, no less.

Which leads to the constant request, when you ask a question POST WHAT GEAR
YOU'RE USING.

In your case it would also help to define what sort of connection you're
trying to make. Point to point, metropolitan, etc.

===================================
Yes these cans work well ; the problem is the type and length of coax .
A suitable arangement is a WiFi router near the antenna (if necessary in
a wx proof box ) with an ethernet cat5 cable running to the equipment.

Another possibility is a USB WiFi adaptor in the focal point of a
satellite dish with a USB to ethernet converter.

I have need of a directional antenna for a 30 foot path within the house.
(the microwave oven wipes out the signal).

Do you have any better details on construction?

================================================== ====
If your WiFi device is near the microwave oven , you indeed have a problem.
In my situation the oven is away (approx 7 - 8 metres) from the Wifi
system ,both router and laptop ,and I no longer had interference when
setting the WiFI System to the highest frequency (channel) with the
microwave oven freq at about 2390MHz.

Yikes! I have never seen that. I would be concerned about leakage.
Sometimes I have torn into things and found stupid stuff like paint over
grounding surfaces or rust in the compartment. There is a critical ground
around the probe entrance.

My microwave oven is in the far corner of the house and I run 100 watts on
VHF and 600 on HF at times and never had trouble. I never tried the laptop
in the kitchen for fear of spillage. The Linksys is essentially on the
floor to keep people in the park next door from ripping up my bandwidth.
(although sometimes I would prefer geeks hanging out there to chase the rest
out) No coverage problems at all. I do have an HT that gets "some"
interference when I set it on top of the oven.
