When the lights go out I would think that would limit the ability of the authorities to control the masses.
What you said.
Could be the first country to be spurred to revolution by a shortage of cat pix and porn. I’d be pretty annoyed, myself.
X 2
The msm never once reported any of them planting gardens or taking down the government.
People lived for eons without twitter and fb. At least won’t be any more death by selfies or sicko up-skirt videos for the duration.
IMO...OR COURSE...
I WILL GO ON TO SAY ANYONE HERE ON FR THAT STAYS WITH FB....MAY AS WELL BE SLEEPING WITH THE ENEMY.
It is not rocket science, but they work very well. And they are simple to construct.
It would not work that far without the omni directional collinear antenna at the access point. It is also important to put the power and network cable at the top of the tower. Or you could use DC power and put solar panels and a battery at the top of the tower. Feedline loss is serious issue when you only have very low power to work with.
So minimize feedline length and maximize gain on both ends. The 4 mile path I was using is line of sight. At 2.4 GHZ and this low of power level it would have to be line of sight to work.
Where I lived in NM we had a remote base on a 9020 ft. mountain top. Nearest power was 2-1/2 miles away. We went up in the winter and collected snow and melted it for water to pour cement base for tower. The hole in the mountain top was dug with hand steel and explosives. It was totally solar powered, with batteries, cavities and RF components in 2 55-gallon barrels buried to ground level with 6” of foam under lid. Only things above ground were tower, Phelps Dodge super stationmaster antenna and solar panels. The remote drew 60 ma quiescent current in standby. The batteries were 2 deep discharge marine batteries. It would cross-link from UHF to VHF and from VHF to UHF remotely. It used ICom IC-2 and IC-4 wired to the controller for programming. The repeater itself used a Repco transmitter and receiver.
At the time it was built, there were 3 like it working in the state. I loved those days.
I remember setting in a restaurant in Deming NM and listening to the up down link of the Shuttle missions from JPL in CA over the Cactus Net (remote base group spanning from LA to Las Cruces NM). We could listen to the repeater on a hand held and during the mission if the repeater was not in use it was piped in. Line of sight radio from the West Coast. Amazing stuff.
Imagine, in the early 1980's walking down the street in Las Cruces NM, talking on 2 watt handi talkie and working another ham in California, on line of sight radio frequencies. Amazing times. (Pre cell phone and internet)
The old light tower that’s been turned into a bed and breakfast off the coast of NC uses a small satellite dish to pull and internet signal from a tower on the mainland over 40 miles away.
Frying Pan Tower. The guy who owns it has the instructions set-up somewhere online.
Agreed. And good to be cautious. There may come a time when we need a back up to our current infrastructure.
Good luck.
Ad hoc Bluetooth networks can be organized.
No electricity, no fuel for generators, no money to buy solar panels... Or radios or antennas...
It is worse than most think.
Still a good option for when/if the SHTF here, but Venezuela is far beyond hope on this.
Right. I live without Twitter and Facebook now. Always thought I was nearly the only one.
Count me at the other one who doesn’t use those.
RE: We’re not on Twitter or Facebook.

How can we make it? How can we not be connected to Charlie Sheen, Katy Perry and all the other thought leaders of our times?
Well placed bullet from a single cartridge?
Some can do that from a mile and a half.
My access point is still in place, but not currently on the web. I’m in the process of updating our house at the farm, hopefully by late summer I’ll be living there.
My shop there is where the access point was hooked up.
I have a long list of RF projects if I live long enough to do them all.
I doubt that is possible without a booster. The home use routers are in mw. Most less than 500mw.
Now this is a current good choice:
EnGenius 11n 2.4GHz Wireless Ethernet Bridge/Access Point (ENH202)
https://www.amazon.com/EnGenius-2-4GHz-Wireless-Ethernet-ENH202/dp/B006M1PKWY/
That is complete unit with built in long range antenna and weather proof enclosure. Far cry from my home brew that is 10 years old.
Here are the FCC standards now:

Yep
This is the best I can find on how the offshore tower gets it’s high speed internet, from their facebook page:
“Math nerds & engineers... grab your propeller hat and sit a spell as we explain how we aligned the microwave dish on a large steel box where a compass needle swings more than a politician in a hotly contested race...
To point the Explore.org 4’ microwave dish at another 4’ dish 56 miles away that we can’t see and since even the best compasses ($300 dollar one!) swings back and forth 15° depending on the where you stand on the helipad, we used the only thing we could see and that was at night, the Oak Island Lighthouse. According to Google maps the light house on shore is exactly at 318.2° so to point at the TV tower dish at 1320’ and 322°, a little trigonometry was required. Thank you high school math teachers everywhere!
Then, using two equidistant strings to keep the dish back plane perpendicular and pointing to the calculated location on the helipad, gave us a solid high speed connection on the first try!”
