Verizon, Cingular data access frequencies

Hello:

I am trying to find out the operating frequencies for Cingular and
Verizon's cellular Internet services, that are used with the PCMCIA
(laptop) cards. Basically I'm trying to find a high gain antenna that
will be compatible with both services, for the slower and higher
speeds (if possible). So far I have not been able to find a complete
list of the frequencies, that include the faster and slower access
speeds. Can anybody point me in the right direction?? I really
appreciate the help.

Thanks much,

Cellular is cellular - no matter if it is data, or voice, high speed or low....

But, what band??? There are two...

To do both, you will need a 'dual band' antenna.
And, I don't think there are any effective dual band yagis...??

~824Mhz - 894Mhz is the old 'cellular' band...

1850Mhz - 1990Mhz is the 'PCS' band.....

I use this wireless amp/repeater...

$400.

Here's the deal... if you want to be able to take advantage of both the
800Mhz band as well as the 1900Mhz band you need either a dual-band system
with omni-directional antenna or you will need two Yagis, one for each
frequency, cabled together into a mixer and fed into your dual-band amp.

Typically, if using a Yagi, you choose one or the other, depending on your
carrier and location, and settle for only one band.

VZW primarily uses 800Mhz. However, in Florida (that I know of) they use a
whole lot of 1900Mhz. Depends on the area. There are others that use
1900Mhz.

For my wireless amp/repeater system I chose the dual-band amp with
omni-directional antenna so I could use it with any carrier anytime. Also so
that visitors to my home-office could also use their own cell phone, no
matter what carrier they had (Nextel being the only exception).

Also, high-gain Yagis might be fine if you have a decent signal to point one
at. However, due to the nature of CDMA technology, and it's ability to use
multiple disjointed signals reflecting from various directions to produce a
single usable signal, sometimes an omni directional antenna will do better
than a highly directional Yagi. Just depends.

This is a highly specialized area and often professional evaluation and
installation is the best bet.

My advice is, when in doubt about your signal area and/or you needs, always
go with dual-band and omni.

I'd go with an LPDA (Log Periodic Dipole Array) like an off-the-air TV
antennas use, err..."like" as in design and construction. They have
slightly less gain than a Yagi, but far far greater bandwidth. It could
cover 500 MHz up to over 3,000 MHz.

snipped from:
http://www.radio-electronics.com/inf...g_periodic.php

The log periodic antenna is a particularly useful design when modest levels
of gain are required, combined with wideband operation. A typical antenna
will provide between 4 and 6 dB gain over a bandwidth of 2:1 while
retaining an SWR level of better than 1.3:1. With this level of performance
it is ideal for many applications, although a log periodic antenna will be
much larger than a Yagi that will produce equivalent gain. However the Yagi
is unable to operate over such a wide bandwidth.

Four, at least.

What about something like this? This claims to be a dual band yagi:
