Also, it would be good to hear more meaningful and beneficial transmissions on the HF bands!
It's not called "amateur radio" for any reason except the lack of "meaningful and beneficial transmissions". It is by nature a playground of sorts.

What a crock of junk "science". These people need psychiatrists, not psychologists.
Use the least power necessary to maintain reliable communication! Also, it would be good to hear more meaningful and beneficial transmissions on the HF bands!
From Alaska, that's legal limit... I can't talk to Art Bell and crew on 75 meters without the Alpha! :D
Personally, I've always liked more fire in the wire. It's always tingling to be mingling with RF.
Lighting up hamshack fluorescents while operating high-power SSB is really cool. :)
Golly, I do RF for a living -- it's that infectious.

The only thing people care about is that towers are eyesores.
The EM waves aren't really a concern to most people.
Most people were irradiated more by X-Rays coming from their TV sets than they ever were by any ham radio signals.
By the way, I do use the least power to maintain reliable communication. Sometimes it's 5 watts, sometimes it's 800 watts, especially when that 800 watts helps me be free of interference by someone who's radio and antenna are too deaf to understand that "the frequency is in use."
EDIT: Just watched the video.
What a POS and what a piece of drivel by knownothings who obviously have a grouse with "eyesore" towers.

Putting 1500w into a dipole or other single element antenna is like driving with your parking brake on, unless it's 160 meters.
Lighting up fluorescents in the shack? My god, Steve. As a ham and as a wireless industry professional, you should be ashamed of yourself. I try to get as little of the RF in my shack, and as most of it as I can towards the ionosphere.

A single element wire antenna (dipole) fed with balanced line or a wire array is the ONLY kind of antenna that one should use. When I started in ham radio I vowed that I wouldn't be caught dead using anything on HF but a wire antenna fed with balanced feed line. I also vowed that I will never appear on any frequencies higher than 7.3 mc

A properly tuned wire dipole fed with balanced line won;t light flourescents in the shack. It will ONLY light flourescent tubes when they're placed in reasomnably close proximity to the feed line or the wire antenna itself.
Seriously, that video seemed to make some dubious claims. Dirty electricity ? Give me a break. And weven if it weere true, filters on the electrical outlets aren't going to change anything. The filters would have to be placed outside at the transformer before the electricity comes into the building.

One could put forth the argument that our words here are prima facie evidence that exposure to RF is extremely hazardous to one's well-being.
:o

Oh, really? So you operate 75 or 80 meters with a 4-square or a yagi 50 meters in the air? Let's see the pics, young man.
Yes... I operated my 5-ele yagi on 10 meters during a contest years ago, when the yagi was a paltry 35 feet off the ground (right above my op position). As the TS-830S drove the large Henry w/ a military power supply, the modulated envelope and CW activity did easily light up the tube fluorescents in the old military barracks. Heck, I only operated 12 hours of that 1989 ARRL 10 Meter Contest and worked 86 countries and 49 states. Wish I could have operated longer... :)
Presently, my home station with an old, yet rebuilt, Alpha only affects the motion sensing light switch in my mud room -- my 75 meter dipole is only 50 feet above it at that point. Oh yeah, my open-wire fed dipole, from the Palstar balanced line tuner all the way to the antenna, generates one of the biggest signals radiating from Alaska on 75 meters. :D

Ah, that explains it.;)

I only got about 1/4 of the way thru the booring video. I knew the butler did it.

The "...based here in California..." was the first red-flag give-away!

So much for encouraging experimentation and technical innovation in ham radio.
To you I say, you're crying sour grapes.

I don't operate 75 at this moment, but my setup I am building now is a foursquare for transmit with 64ft elements and phased Beverages in my target directions.
I have the room, btw. 6 acres of pure antenna goodness.

I operate my MonstIR with 70 foot long elements sometimes directly pointed at my house and nothing seems to get RF in it. It is all properly shielded and bypassed. There are no TVI complaints from the neighbors either.

Good for you. My home station affects nothing.

Give up RF so the other stuff in the world can kill ya anyway :p
Now I'm starting to worry......
My 160 vert is only 25' from the shack,
Part of the 80 4sq is about 40' away, as is an element of the 40 4sq.
All the RF over the years could explain some odd behavior I guess.....the late nites with full strength Coke, the longing for choc chip cookies, being thrilled at seeing the sun come UP so I could go to bed....
hmmmmmm.....

Do you light up any fluorescent lights?
It seems as though our frozen Alaskan friend lights up his whole house with RF whenever he's on. I can just imagine what it would be like if he had neighbors. :)

Learn to recognize sarcasm friend. I have a very dry sense of humor. ;) I'll spell it out. Of course I encourage experimentation. On the low bands... 40, 75, and 160m (where I operate) my preference is for wire antenna's and balanced feed line. Now there are lots of ways you can go with that. From plain single wire dipoles to complex wire arrays.
In my limited space I use an inverted vee fed with ladder line and a link coupled tuner (matchbox). It is a superb performer and delivers an excellent signal. Having the feed point up at the top of a very tall sycamore tree (65-75 feet) helps a great deal. Unfortunately I don't have the space to experiment with more elaborate wire arrays. In Manhattan I would have no room for an antenna. That's why it's at my parents home in the suburbs. Maybe when I head back to Brooklyn I'll have room for more antennas.
I rarely venture above 7.3 mc much these days
Well, now that you mention it.
I had one tied to one of the verticals I can see from the house. On CW it was readiable Morse. But the neighbor actually thought it was funny.
Still, my wife made me take it down......(the light, that is).
I wanted to put up just one more vertical, to get a pattern I could switch on 160, but my leader drew the line at 9 verticals.....
