Which antenna best for panel antenna

There is a municipal wifi transmission antenna about .5 km from my roof.
Can get a line of sight, but the antenna they are using is pointed
downwards on a plaza and I THINK it is a panel antenna. I am approx
perpendicular to it. Sorry I cannot get photos do not have the right
equipment for that.

Have plans for several homebuilt antennas and some dish antennas
available on the net. On the dish antennas is there any rough guide to
which are best for the, is it, 2GHZ? frequency of wifi? Can the tv
satellite antennas be modified for use? Or is another antenna better
since I am not sure I can get precise alignment to their antenna. Others
nearby appear to be accessing this transmission with simple home made
cam antennas. Also I have a tree I might need to trim that seems to be
covering a part of the field between me and their antenna.

I realize this is sketch information and will try to provide better
later, if I can. They have been uncooperative in giving details of their
setup because the really, contrary to the pr campaign, do not want
people using it for free, only businesses.

Hi
You can try any Highly Directional Antenna that is intended to work with
2.4GHz signal.

If it is a "Panel Antenna" and you are perpendicular to it then you will
probably be outside its "Beam Width" and unlikely to be able to connect
via this antenna.It is probably a directional antenna used to provide
wifi access for those in the Plaza.

If this is true then they will prevent your access no matter how you try
to connect to it.

This question, or one suspiciously similar to it, was covered in
excrucitaing detail about two months ago. See thread at

nice try. this guy probably works for the company which brags about giving
residents free access then tries to obstruct people who want to use it,
haha. Tell you and your workers you will be getting a STRONG signal
sometime soon.

Guess you do not know the answer to the question: what design
characteristics make for a good 2GHZ, probably dish, antenna. I wrote
one company that sells these things and their "salesman" did not even
know. It is very funny, whenever there is relatively new technology that
crops up how most people using it do not really understand it, and some
think they are guardians of some kind of secret key that only the noble
are privileged to use.

Some antennas you can try: http://www.freeantennas.com/
And an antenna forum: http://www.freeantennas.com/forums/index.php

Hmm.. Taking into consideration that I was involved with my first design of
Antennae in the late 60's (yeah that is 40 years ago), and doing it On and
Off since then.

There is No General Best-Designed Device. Antennae are measured by their
Gain and the difference between them is in the amount of directionality and
other parameters that a more of the physical nature of the specific
environment (how, where, and what is the mounting arrangements, and the way
it is connected to the Wireless source).

The home build Antennae that proliferate on the Internet has to do with what
the Hobbyist is capable to build with the parts that are available to him,
and the person technical knowledge. It has nothing to do with "Best Design".
For 2.4GHz signal, the Dishes are actually not a good solution, 16 elements
Yaggi would be nice

Therefore, from practical perspective your question is moot question. If you
want to buy an Antenna, compute the Directionality Angle, buy the highest
dbi that you can find (afford), and make sure that the type of Antenna that
you choose can be physically installed safely in your specific environment,
and connect correctly to your Client WIFI.

If you want to make one, make what ever technically you can find parts to,
and have the mechanical know how.

You want to try something inexpensive this might help,
