content: I don't see anything wrong with this.We don't know what was in front of the horn or how far away it was. It there was a wall nearby it would be stupid because the reflections would be powerful enough to harm him but if it's a large empty garden then what's the problem?

content: More danger in the MOT driving the thing than in the u-waves themselves.

content: Uh.. the MOT is fine if you know what you're doing with respect to HV stuff. The microwaves on the other hand have a very high probability of giving you cataracts if you're not careful where you point the thing.

content: As an Ex merchant marine radio officer who undertook the DTI Radar maintenance training I am not at all impressed with the guy's microwave knowledge or his 'expreiments'...... he is worthy of a Darwin Award which, if he carries on in the way depicted, he should win real soon.Any prat who builds a 2.4GHz CW transmitter capable of around 650W to 1000W injection into a gain horn, and who fires it up outside an approved RF test range with controlled space is both irresponsible and acting illegally (in the UK at least). Such a Heath Robinson set-up is not licenced to operate in free space.Microwave energy at these levels is really bad news if not handled intelligently. Ask any qualified Radar engineer, there is a reason why we wear microwave energy alarms when we work on Radar systems on ships and aircraft....you can't predict where the rear and side lobes will appear or what will reflect significant amounts of energy towards you. Didn't I see a metal tape measure in the main RF lobe and metal (uW reflective) objects being dangled in the mouth of the horn in that video ?.... Numpty. Think about firing a jet of water out of a hose pipe and then dangling an object in the stream close to the nozzle...lots of spray in all directions in an unpredictable manner results.... get the idea ?Before anyone decides to flame me, think very carefully about whether this guy is operating in a safe and sensible manner ? Or is he a daft DIY'er who likes to play dangerously ? Would you want him as a neighbour if you had your children running around in the garden adjacent to his 'experiments' ?Rant over, but these kinds of experiments horrify me. If he is only risking his own cellular damage, fine, provided he is a LONG way away from civilisation when he does it.

content: er, I don't know much about antennas and propagation modes/orders, but I don't think that stupid rectangular cone guarantees directionality; nevermind reflections. Aren't there RF alarms and crap, just like personal gas monitors in the oil & gas industry, one wears when working with this exactly because of its unpredictability?Great video, though -- I am entertained!

content: Unless you have a pace maker you probably shouldn't worry. You'll feel a little warm and move out of the beam path. The end. I worked around MW and GW type systems and am pretty familiar with weaponization abilities of such beams.The high voltage is 10x more dangerous.
