    Okay guys... Most of you recall that I moved to 12 acres that is on the edge of cellular coverage. I am running a Netgear AC791-L Verizon hotspot. I also bought the 5dB booster cradle that is also a charger. This setup nets me 1-2 bars some of the time but usually just 1 bar. So I am usually okay with email and most websites that aren't video heavy. I obviously cancelled my Netflix subscription! :( I am pretty much sure the cradle is useless

    The Netgear Jetpack has 2 antenna connectors on the bottom. I bought the corresponding male connectors (Male TS-9) to plug into the Netgear jetpack... But I am having a hard time deciding on what antenna to use. Will a custom made Yagi antenna be best... Or can I convert an existing antenna type. I am lost in the world of tuning antennas for a specific purpose. I have usually relied on a coat hanger!

    Thoughts?

    yagi's and cantenna's work great BUT they are extremely directional. Very narrow reception window.

    i pre-built yagi tuned for the frequency range of interest is the best option for gain vs side/rear rejection and narrow beam angle .
    check with the telco or cable provider ...
    they might be able to put up one end of a system on the edge of your property and you can put the other end up at your house .
    you are going to have to get above the trees .
    do you have a map of your property ? if it shows where and how far the cable/telco could put something in , then it would give you an idea of the costs .

    there are systems that ul/dl via ethernet (cat 5/6) .
    the transceiver head and antenna sits at the top of the tower , this eliminates an expensive run of something like LMR400 .
    if you don't mind the high cost of cellular BW , you could go with this and it can also be used with a wireless link from the telco/cable company .

    Well... I wanted a fairly low cost, home built alternative. Otherwise I'll call Hughesnet... With their Gen5... which I hear is pretty good. But their customer service is ZERO stars! I know the direction of the towers... But it is going to be hard to get above the trees... They are hundreds of feet tall!

    one word ... "skyhook" .
    :p:D

    as long as you have a clear path/line of sight to the towers , you can most likely do ok .
    the trouble with a "booster" is that it will amplify noise as well as the wanted signal .
    if the wanted signal is too low , then the amplified noise will desense the front end of the receiver .
    this is why a good antenna with the required equipment mounted at or very close to the antenna is the best answer .

    That's what I thought you might do, is get satellite, but even today for interactive use it's got too much lag, even with the terrestrial back haul link for ack's.

    You might want to contact your local government and see whose registered for communications services in your area, as there are lots of Rural ISP's that spring up just for these situations. It's going to be a local solution for high speed access.

    But, you could always go with the Anchored Balloon solution to get above the tree-line. :)

    Balloon carried antenna

    Publicatiedatum 26 april 1966
    Aanvraagdatum 17 jan 1962

    "The present invention relates to antennas for use in television and the like. The invention is believed to have particular application to homes, although it can be employed in connection with industrial establishments such as gasoline stations, restaurants, or in communication system engineering as a probe antenna for antenna site determination.

    The invention also has significant application in the military services during war time. It provides a means of highly directional radio transmission in an enemyheld location where it would be highly desirous to quickly elevate the antenna to any desired height for the transmission and then quickly lower it for concealment or to move to another location."

    IDK if we will see LEO's (NGSO's) which have low Earth orbits giving far better latency here in the US, maybe there are already (I don't think so, at least not publicly available), but I have seen them proposed early on and used now for Cellular / Internet in other countries.

    This is the only one that is approved and funded, I think, and close enough to release to mention, coming in 2019:

    Low-latency satellite broadband gets approval to serve US residents
    OneWeb's 50Mbps Internet with 30ms latency could hit remotest areas by 2019.

    https://arstechnica.com/information...roadband-gets-approval-to-serve-us-residents/

    "OneWeb is planning global satellite Internet access and gave Airbus a contract to build the satellites two years ago. OneWeb says it will start launching production satellites in early 2018 and potentially begin offering Internet service the next year."

    FCC grants OneWeb approval to launch over 700 satellites for ‘space internet’
    Coming as early as 2018

    https://www.theverge.com/2017/6/23/...eweb-approval-satellite-launch-space-internet

    OneWeb
    http://www.oneweb.world/
    http://onewebsatellites.com/

    "OneWeb and our partners have been making great progress. We will soon provide more details of our roadmap, which includes greater than 100x capacity growth from our first generation system, including Gigabit per second speeds, lower latencies, and affordable self-installed terminals.

    These new capabilities will support both our 2022 goal of connecting every unconnected school and our 2027 goal of bridging the digital divide. At the same time, boundless low latency broadband access will be available for homes, connected cars, trains, planes and cellular backhaul applications.

    In early 2018 we will launch an initial 10 production satellites, which, pending a detailed test regimen, will become the first of our fleet. Six months later we will begin our full launch campaign and start providing low latency broadband access as early as 2019.
    We have a lot to do between now and then, but it is a good time to say we have appreciated the tremendous amount of global support we have received. This is not just our mission, this is everyone’s mission—and we are really glad to be a part of it."

    This kind of project can come and go quickly, not making it to market, but I'd track it for future potential use.

    SpaceX and others are talking about LEO's, but IDK how close any of them are to being funded.

    man , my memory is getting terrible ... i read about this in the early 60s (maybe the third grade ?)
    there was a project that was actually given a trial run ...
    it involved a DC-6s and converted military cargo planes , a bunch of tv broadcast equipment and flying in a circle at altitude .
    the idea (partially) was to receive a signal from the ground studios/station(s) and rebroadcast it .
    some origination of content at/in the planes was also tried .
    (can you imagine the QRM ?!)
    at first it was used to extend the range of educational television for schools in remote or educational non-service areas .
    the program was first implemented in the midwest .

    I have a WeBoost (Wilson) system that I paid over $1k for just to rebroadcast the cellular signal into the house. I have the antenna up in a tree... A cable running down the trunk and into the basement to the amplifier... Then a cable running up into a wall where I mounted the rebroadcasting antenna. Here's the issue...

    At 55 years of age there is a shrinkage factor in ball size that allows me to only go up about 25 feet into the tree. My extension ladder was maxed out and I am not playing "Wichita Lineman" out here! I did have a neighbor say that "he knows a guy" who could mount it further up the tree but I need to contact Wilson to get a longer run of cable as they work best with no splicing or connectors in the line. But that just allows for better cell coverage while using phones inside the house... But I am sure it would also help the hot spot that I have. I know this system helps a little as when the power goes out the cell coverage is even worse! So perhaps I will contact Wilson for a longer run of cable and my neighbor to get "his guy" out here.

    One bright spot... My 25kW Cummins whole-house generator is on the way on 10/24. It is commercial grade and will run about a month with judicious use on my 1,000 gallon propane tank buried in the side yard.

    Yes... I have seen the balloon systems and I too remember the , "We'll have C-130s with broadcasting equipment" era. There has been on and off talk from Google and others about coming up with low cost alternatives. However... Low cost means low profit. Sort of like the cheap cure for the common cold would cost big pharma companies billions in profit...

    You might see if there are local Amateur Radio "guys" or a club that could do a good job replacing the control / signal coax cables for minimum loss.

    Those "guys" usually have access to equipment for climbing + ladders + platforms on a vehicle for pucker-free elevation (just don't look down).

    Depending on the configuration of the device / antenna, you could also use a bow and arrow to shoot a line over the tree of interest and pull up the whole shebang to get it elevated. Crossbow's are cheap :)

    Wrist Rocket Slingshots work too!

    Even a Nail-gun driven Dog Training Bird launcher :)
