Fractal antenna for clear wimax modem

[anon1]

I have a Clear modem and I am close to two towers. But
still only get 2 or 3 lights at any given time. I plan on moving into the
country this summer and the towers will be further away. So an amplification
unit will be needed.
I was talking to a friend about fractal antennas if they were made large
enough how good would they be?

Fractal antennas are typically useful for wide bandwidths and this typically
means that they offer low gain. One such antenna is the log-periodic dipole
array (LPDA) antenna here:

Our most popular clear antenna is however not a fractal antenna and covers
only the WiMax band 2.5-2.7GHz. This is the 18dBi panel:

You can get this as part of an antenna kit here:
http://www.rfwel.com/shop/4G-USB-Mod...tenna-Kit.html where you
can select cable lengths, pigtail for your CPE/USB modem and lightning
protection if required.

Note that these are NOT "amplification units". There are currently no
consumer amplifiers/repeaters for Clear WiMax. This means that you are
limited in what these antennas can do. These antennas are NOT for extending
coverage much above where the coverage zone ends. Rather these are for
improving indoor coverage. So if your outdoor signal is quite strong but it
gets weak indoors then these antennas will definitely help. If you cannot
pick up a strong signal within several feet of the outdoor location where
you could mount an antenna then it is unlikely that any antenna would help
(not even our most powerful 24dBi grid antenna).

Hope this helps and let me know if you have additional
questions/clarifications.
