Wisdombylearningtruth :): can those radiation waves effect us
Daniel Stinebaugh: excellent explanation and demonstration, Nice work Diana!
TheMan1510: This is the best demonstration of how a directional antenna works that I
have ever seen! Thank you very much for posting it as it has really helped
me to understand how each of the elements contribute to the antenna's
Robert Mitchum: A very nice explanationon on the simple physics on how a Yagi works. We can
get into antenna patterns and side lobes at a later date. I really love the
idea with the light bulb, a perfect way to show the lensing effect the
reflector and the director have on the dipole. Do you think an explanation
of the inverse square law, and the laws of reciprocity, would be too much?

Circuit-Breaker Mi: Voice looks dubbed in like a cheap "B" movie from the 50's. Good facts tho.
Robert Russell: Dam girl, ur too fine. your voice seems laggy though.
scott91372: Very good video.
VViitard: wtf, thats my aunts name lol
leloodallasmultipass: awesome. luv it.
SouthTuningSwiss: Nice vid! 73`s from HB9THC ;-)
PetrFM: Geek chic
Bousho: imagine 300 of these, pointed straight up, pushing 50 BILLION watts of
energy into our upper atmospheres... think that might create some problems?
jim hale: Nicely done. That makes it real for me.Thanks!
subtler1: @VisionQuest2012 amateur radio operators use these satellites. which were
put up there by amateur radio organizations. that's who uses them. they can
speak to each other.
Tafheemwii: You would? I'm pretty should I wouldn't..
mashurst: What a great way to explain the yagi! I love the light bulb setup. I'm so
making one. thanks
Nader Omer: Great work tnx for the wounderful viedio ,FB, 59 PLUS notice:- make sure
not stand infront of yagi while transmmiting . safity first :-0 73&88 ST2NH
Roy Lewis: Excellent demonstration; very instructive. First time I've hear of antenna
elements referred to as mirrors and lens. Keep up the good work!! RL

PrisonEarth: Wow Diana you are so perfect
zooky443: You are amazing.
ClamChowder44: hey you're from project runway
pinchiecajones: you can even use a yagi antenna on a uhf & scanner radio
tj7729: Wow, that was really helpful to understanding the reality of yagi's. I've
always 'known' they work but never thought it could be so clearly
demonstrated. Nice job!
kahvac: Excellent video ! the demonstration was very clear and easy to understand.
I just might build my own. Thanks for taking the time to make it.
Kishore Vagisetty: hi diana, ur fantastic in explaining the yagi antenna !!
Bees Bee: What would be amazing is if someday they can use this type of technology to
charge portable devices such as laptops or cell phones
mark nunez: hot smart asians XD
mongojerry72: Nice demonstration. A fashion designer with brains? Refreshing combination.
VonDenHottentotten: I've seen sweeter. The glasses ruin it for me. Oh, wait, dude! This video
isn't about cute women.
Jacobsenacc: Yea, I seen a demonstration made by some large company, lighting up a
lightbulb from across a room. But they said then it was dangerous from
doing it across a room.
QatarOwner: nice video 73a de A71CV
Christopher Gillespie: OK, have it your way, Kelly. I guess all those FCC cars with DF loops
trying to triangulate (horror gasp) operators without a license, but who
otherwise respected the courtesies of vox operation... were all our
collective imaginations aye? Enforcement for Enforcement's sake (oh, and to
get the money out of their pockets which THEY OWE US!!!). Just catching
gross interference were they? Sure, sure. I don't think we've anywhere much
left to go with this convo. Have a good one - and cheers.
The Faustian Man: Tesla was right about sending power through the air. Too bad he ran out of
subtler1: @YoLninYo that antenna looks definitely home brew. do you have proof she
did not build it herself?
HGarden27: o i see... well there must be a way to keep power in a wave like from. i
think that once we figer that out we would be able to work in small worm
holes in time.
flahr1: @catmaster141 any alternating current in a wire creates radio
waves...simple huh Satellite TV, Cell phones, microwaves, bluetooth etc.
all transmit are radio waves with different frequencies (of alternating
MorikoKitsune: wow she is just every where...she has been on threadbanger several times.
Probewitch: Sweet. We could use a teacher like that to tour our motorola centers.
2627mhz: Good job...
Jacobsenacc: It looks like this technology could really send small amounts of
electricitry across a room... Too bad you get radiation poisoning if you
use it for that purpose. Maby we could power more than a lightbulb in the
patrickdarcy: well done
catmaster141: Yup, thats already an idea, having giant solar panels and space and then
beaming the power down in the form of radio waves and collected in giant
areas on the ground. Its being tested on a smaller scale.
sneakerset: Diana's set-up is a home-built cross-polarized dual band antenna(2
meter/transmit and 440 mhz/receive). For a more detailed breakdown of the
operating aspects of LEO Amsat birds(including avail. freqs.,passes,and
Doppler shift) please visit YT user K7AGE....or (Google)Amsat (Emily's
primer for new users).
Jakob Huels-Elliott: He also had a love for pigeons :P Creepy guy.
SoloTotoCoyote: Cool......... although there's probably some poor guy in her apartment
building wondering why his TV reception has suddenly gone bonkers. =D
Gutpile Charlie: Very good video, very informative.
