Where can I get a "interframe gap"?

[theeWidow]

wifi uses the 2.4ghz frequency... doe does your microwave... hence some of the "health risks".

[venxxxxx]

thats less radiation than opening up a microwave oven when its still running. No one complaints about that one...

[rkan2]

In Finland the limit, which is 100mW, is for a dipole antenna. When the antenna is a direction -antenna the power needs to be deamplified by the same amount as the directional antenna focuses the "beam" So if 100%(radiates 100% of 360 degrees) dipole antenna transmits 100mw, a directional antenna which focuses the beam to 5% of the dipole antenna's range can only transmit 5mW. Please do tell me if the regulation is more open in the US!

[IBMClynes]

The ERP of a 50 watt light bulb is 50 watts, no problem looking at that !

Would you look at a 50 watt laser no . He talking with out a complete knowledge of RF.

The Yagi focuses the RF in to a beam like a Laser.

This is the guy who takes the clip out of a gun and says look it safe now, and blows his friends head off , Oh i did not understand that there was one in the chamber!

INSTA CANCAR!

Love pauls vandam face at the end lol

Google: "Smart Meter FCC".

The FCC licensed these meters even though they violate the radiation exposure limits.

[DackIsBack]

The FCC is full of shit, those new smart-meters use a 1 watt (sometimes 2 watt...) transmitter that broadcasts every 3 mins, Which is multiples over the allowed limit for regular consumer devices.

It's hypocritical of them to license an electricity meter to a corporation when it clearly doesn't meet their standards, but it's illegal for you to use one of those antenna...

It's all about money, they don't want anyone competing for the airwaves with out a bidding war that gives them all the $!.

[TiredOldFart]

Part 15.247 says (i) Systems operating in the 2400–

2483.5 MHz band that are used exclusively

for fixed, point-to-point operations

may employ transmitting antennas

with directional gain greater

than 6 dBi provided the maximum peak

output power of the intentional radiator

is reduced by 1 dB for every 3 dB

that the directional gain of the antenna

exceeds 6 dBi.

funniest episode

[carlitosvodka]

great episode. more informative, people should know that they have more control of their lives more than the government and IEEE but responsible enough to know and face the consequences. developing awareness and informing people are the first steps to make educated decisions. similar to not paying tax or jaywalking, agoing a little over the speed limit/ allowed limit of modulation, etc. everything we had power to do in the beginning, we werent born with regulation, but they help.

Blladerunner

[flahr1]

1 watt is not going to hurt anyone. This low limit is for interference purposes only,

You can't increase the power output with an antenna. The gain is because it is not an isotropic antenna. The yagi is more "powerful" because it transmits more power in one direction then a isotropic, hence the "gain".

[umeithou]

Nothing like promoting unsafe and illegal haks.  I'd imagine that the small amount of power coming off that antenna will do no harm...but putting your eyes and head right into the minor lobe of the radiation pattern of an antenna? Great tips...

[umeithou]

Your wifi transceiver might be well within the ERP limit. But when you add 16 dB of antenna gain...what the viewer is saying is you are now over the ERP limit when you combine the transceiver output plus the antenna's gain. While this is still a small amount of power and the antenna is rather directional you could still be interfering with other transmissions. You are most likely interferring with someone else's wireless telephone or wifi internet. Do a little research on harmonics...

[flahr1]

@umeithou SO how does an antenna create more output power than the input? Do a little research on gain.

That PAUL, Epic outtakes

[blake9753]

I didn't hear the beginning of Shannon's story because I was distracted by Darren's Easter egg!

[BLACKBINLATIN]

Paul The Fucking Camera Guy!!!

[rhblakeman]

If the FCC is letting 2000 watt CB radios slide that bounce signals across the US they surely aren't going to mess with someone running a full watt and a yagi. Hard as heck to find to begin with where Cletus with his modified CB Eagle and 2kw kicker and gigantic beam on a 50 ft tower are easy to find. Now in the 70's the FCC did do the Gestapo thing with CB and over power and out of rules transmissions. Saw them take down a neighbor's antenna and walk out with his base radio in 75 in Chicago

[m0dm0use]

Love the easter egg though you could have said bla bla bla boobies bla bla bla *_+

[MrJakewoodall]

we need more of them easter eggs ;)

[fidgejufter]

Whilst there's a limit for total irradiated power, and Darren's right when he sets it to just 500mW, it didn't address the second issue. Just like how my laser at home is a tiny tiny 50mW, compared to, say, a 60000mW (60W) incandescent bulb, the bulb sends that energy out in all directions, but the laser concentrates it onto a small area. The laser can burn through thin plastic at several metres, and the bulb wouldn't. This set up might not be a health risk- but it is important to check.

[ShadowRayzzz]

Great Ep

[spikespeigel]

what are the penalties for violating an FCC violation like that?

[DjViOd]

@spikespeigel they come to your house and kick your butt, seriously... (I actually don't have a clue)

[Djhg2000]

Thumbs up if you saw the easteregg

[thewrongguy]

Good show

[stalingbg]

It's named wrong.

[0MichiganExotics0]

and about the email its not illegal if you use the antenna to get the signal u can put 15W and still legal. transmitting signals that's different mater

[MAZiERNiCKi11357]

EASTER EGG!!!

[k2kraze]

1000mW sounds really redundant, why not just say 1W O_o

[EyesOnMeStudios]

"001101 your mother!" Thats amazing :P

[calvcoll]

Darren's Easter Egg XD

[DiyEcoProjects]

# Dear Shannon, You are like sooo gorgeous! (grrrowl! rubby thy!) #

Thank you everyone, i enjoy your videos.

[zaghy2zy]

right that moment you started the easter egg, I was really looking at it...., and I was watching this for the first time
