Boston911Truth pamphlet

[technoextreme]

Found some pamphlets called the 9/11 "fact sheet" from Bostons group of kooks. I was reading the pamphlet just out curiosity and became extremely confused by the term dF. Eventually I realized that whoever wrote this couldn't find the degree symbol in excel and just thought it was a suitable alternative to use dF. Is this correct? After taking electromagnetics Im also confused by the cellphone tower assertion? Wouldn't the transmitter antenna radiate the waves in three dimensions?

No. dF means "the change in the variable F." Without a degree symbol, correct usage would be "deg. F," or, informally, just "F."

I'm in mechanical engineering, so I'm not completely certain, but I seem to recall reading that the antennas are optimized to direct signals toward the ground.

Im electrical. I should know the answer to this eventually.... All I know right now is that once the radio waves hits the ground some of it actually bounces back up and some of it starts off into the ground.

I knew that. I just wanted to make sure that I wasn't missing something.
Anyone know what pamphlet this is. www.911weknow.com presumably has it on their website. It's nothing really all that new except for the cellphone assertion. At least that I can argue fairly easily because Im an EE.

They have a poll up on the website which claims it is there to see where people stand on the issue. I had hoped to cast my vote amongst those who think the so-called truth movement is misguided but of course that was not one of the options... here is the false dichotomy they are setting up:

Where are you in your thinking on 9/11?

New. First time I've even thought about it.

Uncertain. Taking an objective look.

Serious questions. The science is the key.

Scared. What are they going to do next?

Angry. We have to stop them!

Convinced and confused. Who are THEY?

I know this is much bigger than 9/11 and our government.

Foreigners who were not Arabs engineered this.

9/11 was for money, oil and perpetual war.

It was the work of the power elite and secret societies.

The levels of control are dark and not of this earth.

9/11 is a way to build a new world through cooperation, love and awareness.


The name of this poll should be just what kind of a nut are you?

Sofia's a complete space cadet (as if you couldn't guess from her narration of 9-11 Mysteries).

PS--Welcome to the Forums!

Welcome, Waltdekind! And yes, for all their self-labeling as truthseekers and open minded individuals, they sure have a closed view of things.

Although I admit, some of those choices read somewhat tongue-in-cheek. I mean, "9/11 is a way to build a new world through cooperation, love and awareness"? That to me sounds like an indication that the pollster is not taking the poll all that seriously.

ETA: Oh, wait, that poll was by Sophia? That explains a lot, actually.

I got the impression from your OP that you had gotten ahold of a printed pamphlet. Any chance that you could scan it and post the images?

I started looking around the 911weknow site, but retreated in disgust when I saw that they were recycling the same old damned lies about WTC 7 being "pulled" and collapsing in 6.5 seconds.

I often wonder if NWO little people are hiding in all of those displays that they crowd down the middle of the aisles.

They do have a response in three dimensions, but cell base station antennas designed so that most of their gain is in the horizontal direction. Is that what you're asking? An antenna broadcasts pretty much all the power it's sent by the transmitter, but the whole deal with antenna design is to direct the coverage where you want it. The "gain" of an antenna is the ratio of how much power it's putting out in a certain direction, versus how much an ideal antenna that spread out the power evenly the three-space would put out (isotropic antenna).

But even an antenna with a high gain (very directional) still spills out power in the other directions as well.

No, you weren't missing anything. And my explanation wasn't just for your benefit. :)

[rf dude] Yup, cellphone towers direct most of their energy towards the horizon with a relatively narrow pattern in the vertical plane - the pattern for an omnidirectional antenna looks like a flat doughnut, with the transmitting source in the middle, while a sector antenna would be wedge-shaped, like a piece of pie.
