That is the only way to get actual gain from a (horizontally)
omnidirectional antenna (excluding any MIMO designs).

Flattening the vertical radiation pastern may have severe drawbacks
especially if the mast is swinging in the wind or some weak (e.g.
indoors) users are close to the base of the mast.

Any excuse to raise the noise floor--

I didn't mean for you to take that as a suggestion. You don't have to do
what I tell you to do. That's what we have the news media for.

OK, time to clarify...

You still don't describe what sort of connection you're trying to make.

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.

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,

I recently built a Franklin antenna for 2.4Ghz.
I highly reccommend it. Google WiFi and franklin antenna.

Also look up AMOS antenna. They are easy to make and work well

You actually think I might ... damn, I'll work on my image! :-)

Wifi (2.4 GHz). outdoor omni vertical (not whip), permanent mount on pole, to
be connected (very short pigtail) to pole-mounted wifi router in client mode.
Max output: 250 mW.

Is it true that the higher the gain the flatter the "donut" shape of the
sensitivity field?

(And yes, my terminology is rudimentary... please forgive.)

Thanks,

Then this should serve you well:

Jimmie:

Excellent link, thanks; I will homebrew this when I get the time ...

However, with the reflector plate, it is not OMNI; but, for me this
would NOT be a problem ...

Good work,

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.

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

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.
