You’re correct, sir.They won’t, no resistance. Unless it hit another planet or something interacted with it.

So, they do get weaker the further they travel?Radio waves dissipate in line with the inverse-square law:

Not in the vacuum of space they don’t.So, they do get weaker the further they travel?
Thanks for the link.
Holy $hit!Oh man, you can use your radio from your vehicle as a base with a power supply. If you want to reach out and talk on the 11 meter band your antenna needs to be high, it needs to be in tune with the band and you need power. Same with the vehicle.
Do you want to talk side Band and different bands? If so you would have to go with a 10 meter radio with band selection. I used a magnum s9 in my truck and in the garage, a lot of swing and great audio. I also used a galaxy 95 t2 which has a built in amplifier, swings from 40-200 watts. Great radio for the truck, and you can put it into a big amp in the house so you can push something big.
In my house I was running a cobra 2000, tuned with mosfetts so it swung from 10-50 watts, into a Texas Star 350 hd which turned 10-50 into 100-350, into a 2 tube bugga bear. So I was dead keying 1200 and swinging up to 4700 watts. All that was hooked up to an i10k antenna on 65 ‘ tubular tower. The big amp heated my 1200 sq ft garage after about 2 hrs of talking .
So the 2000 was plugged in the wall, the TS 350 was on a 40 watt power supply, and the bear was plugged into 220 . In the truck I just ran the galaxy 95t2 that was enough power to put a lot of them back QUIET . In the truck I ran a Wilson 1000 roof mount antenna, really don’t need any bigger unless you are gonna run over 1000 watts.
So the antenna has to handle the power you are gonna put through it, it has to be tuned to length for the band you are gonna talk on for receive and so it doesn’t fry your radio, if the swr is high it is reflecting the waves back into the radio. Like if your water spigot isn’t open enough there is resistance there. It’s affects everything. Tuning the antenna is key to the system .
If you are gonna run an amp the radio is suppose to be tuned to it also. But as long as you know what the radio is doing and what the amp can handle u should be ok. A big amp needs a lot of power to get to its full potential. If it is under powered like a cobra 29 running into a straight 8 pill box it is not gonna put out it’s top power, but won’t affect anything like modulation. But if you run something with 3 pills into an 8 pill it might overdrive it and .
U can have shops tune your radio, there are a lot of good shops out there do research and go to the right one. Don’t let any yahoo in any truck stop touch your radio. Your radio is like your women, only gets the finest treatment when needed, or your hound dog, depends where life has put u . There are cool things like nitro knobs, different colored displays it’s nuts. My s9 had the blue nitro knobs and display it was ridiculous. I had.a cobra 29 that was all red, knobs, face cover, wrap, the face cover and wrap were red diamond plate.
Get yourself something like a galaxy 959, have it tuned, run it into a 2x8 Dave made, with a Wilson 5000 mounted on the roof of the truck. You will be stepping on necks and putting them back quiet. Get yourself a power supply and run that same system into a mako 5000 or an i10k antenna about 60-80’ in the air and they will hear you for 100 miles.
If you need any more info hit me up, Misfit right around SoCal in the dirty dirt pile of the hi desert I call home, and I’m gone now.
Idk. How far?How far can the planet you’re living on be to hear that Japan has just surrendered, as it just happened in real time?
Once the waves enter the vacuum of space they travel at the speed of light. It’s a simple formula knowing the speed of light and when Japan surrendered.Idk. How far?
Japan surrendered 75 years ago, so the radio waves announcing it are 75 light years away. But they are very weak now, almost background noise. Radio waves do lose intensity over distance in line with the inverse-square law.How far can the planet you’re living on be to hear that Japan has just surrendered, as it just happened in real time?

Distance is the factor, not the medium.The vacuum of space doesn’t apply to the law.
“Weak” compared to what?Japan surrendered 75 years ago, so the radio waves announcing it are 75 light years away. But they are very weak now, almost background noise. Radio waves do lose intensity over distance in line with the inverse-square law.
A magnum s9 is a really bitchin radio. They do the same as any base station, it has side band, and will go down into the 10 meter band and also up above 11 meter, but u have to plug it into a power supply when running in the house. For the car u can just run a power wire right off the battery to the radio, and run a magnet mount antenna and run the wire however u can get it back into the car without drilling any holes. I would get the Wilson 1000 for barefoot radio. If you want to drill a hole on the top of the car and run it above the headliner and down the pillar to the floorboard get a roof mount. U can tune the antenna with the swr meter on the radio it’s just hard to judge if it has to go longer or shorter. You do this by cutting the whip ( the metal antenna) that plugs into the base of the antenna. If you have a radio shop near you u can take it in and have them tune it after the install.Holy $hit!
I have no idea what you said, but I'm impressed.
I don't have any women. I live in a mobile home, and drive a Saturn wagon.
While i am interested in learning more about all this, right now I just want something I can use in the house, or in the car, to communicate with the outside world should the internet and/or power go down. That's my immediate goal.
Long term, who knows? The sky's the limit, right?![]()
Weak compared to when they were first transmitted. The more distance travelled away from the transmitter the weaker the signal gets in line with the inverse-square law.“Weak” compared to what
I suppose you can say this is technically wrong. I consider “weak” as being a means to an end. A radio wave in the vacuum of space will always be there and never end, it will always be readable if you have the technology to read it.Not in the vacuum of space they don’t.
To me, the definion of “weaker” means eventually it’ll be non existent, or useless, I believe that to be false. They will always be there, it’s just whether or not you have the technology to hear it. But to keep on topic, I’ll concede to what you’re saying.Weak compared to when they were first transmitted. The more distance travelled away from the transmitter the weaker the signal gets in line with the inverse-square law.
