We aquired 2 surplus millitary 1kw 2100-2800mhz Wideband amplifiers and
hopefully will do a test run sunday using 2 24db parabolics. the locations
are 10miles apart should I get a 11mbit at that distance using the 1,000
watt amps and 24db parabolics. What distance can I expect with this power?

With 1,000 watt wideband amps & 24 dB antennas? Oh, I'd say you can get at
least from your house to the jail when every device that operates close to
2.4 Ghz within 3 miles goes down.

You'll probably burn out almost every cordless phone in your neighborhood.

There'll be aliens from distant galaxies contacting you for hundreds of
centuries about your broadcast. Never mind the multitide of microwaved
birds and other flying objects that will hit the ground immediately upon
you going "live".

You *MIGHT* be running the RX side of the link a bit hot. If you see some
packet loss, stand between the antenna and the remote end. Try to keep your
torso within the mail lobe. This should provide all the attenuation you
need.

Keep us posted!

Interesting e-mail address.
A: If you worked for NSA I doubt you would advertise it.
B: If you worked for the NSA you have access to equipment the is far better
than 802.11x
C: The Government frowns on its employees doing illegal acts (Unless told
to)
D: I think impersonating a federal worker is illegal.

1000watts, 24db gain... dbd or db? Lets say that 24dbi is equal to 8 times
the power, taking into account that ever 3db is twice the power, this means
8000watts.

I bet the aliens are just going to keep quiet and try to steal his
bandwidth, better enable WEP and MAC filtering.

It is. I have yet to see it extended to the forging of a e-mailbox address
though.

Another math challenged individual?

Each 3dB is 2x power, and 24/3 = 8, so that should be 2^8 or 256, so that's not
8kW - it's more like 256kW (ERP).

Obviously, the original poster has other issues.....

Your math is off a little. it's actually 1000 X 2^8 or 256,000 Watts EIRP.

Hugo reminds me of a young friend who thinks always of high-power lasers and
nuclear explosions and other extraordinary phenomenon. Hopefully he won't
get his hands on any of that stuff until he's old enough to possess good
judgement. Hopefully the same is true of Hugo.

Probably very little more than you can expect from your 'barefoot' AP. With
line of sight it doesn't take much power to establish a solid connection.
Without line of sight a 1000 Watt signal may not ensure a solid connection.

I've stood next to a very remarkable antenna and transmitter at Arecibo,
Puerto Rico. The gain of the antenna at 2.4 GHz is about 74dBi. The
diameter is one kilometer. At the time (about 1990) the Arecibo Radio
Observatory claimed to have the most sensitive receiver in the world (liquid
nitrogen cooled GaAs) and the most powerful transmitter in the world (6 MW
continuous, if I remember correctly.)

If you really acquired 1 kW amplifiers, they'll output only slightly more
power than your microwave oven, but you'll find the oven to be much more
useful.

If you want to engage in something REALLY fun, enroll in astrophysics at
Cornell University and spend a summer in Puerto Rico. You'll never forget
it!
