    So our new place is 5 acres on the south side of the city and appears trapped in the past. Bordered by two subdivisions and two schools, yet we cannot get high speed internet here. No broadband, no DSL, and no skybeam either.

    So I'm trying the Verizon Jetpack MHS700L 4G LTE for access to motorcycle porn. With a good signal, speeds are up there with faster broadband but more expensive by the gig.

    Of course, signal sucks at the house. I sit around in the building with -98db to -104db. I jump on Amazon for an external antenna and pick up:
    http://www.amazon.com/gp/product/B00ICN2KSW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

    Mounted on the house and brought the signal strength to -83db. I tried going higher on the house and signal strength remained the same while SINR dropped from -2db to -9db. It appears that my signal isn't terrible by LTE standards but the SINR is bad.

    I'm wondering if there is anything else that can be done and done affordably? Verizon antenna is 1.66 miles away and on top of a hospital if I can believe what I find on the internet. Photos of install:

    I would put the antenna higher up if you have the cable. I am curious though.... you are able to get verizon home phone service right?

    In the Finger Lakes in NY, we used to run 802.11 twenty miles, point to point, BUT, the antenna's were highly directional and 100-200' on towers. I had an antenna at my house that shot 13 miles across a lake to my friends tower. Get a directional high gain antenna (if it is not already), and get as much hight as possible. Short of spending big bucks for RF amplifiers, that's the best you can do. I also used high gain UHF antenna on roof of house with an amplifier to go 60 miles to Syracuse for network channels in HD.

    Just looked at your specs on your antenna, that is probably the best you can do there, weak signals are best line of sight, can you see antenna on the Hospital? Is their antenna pointing towards a denser populated area? Maybe not radiating in your direction that well. Company called Wilson make cellular amplifiers. I live in a metal box, so I had to get one of those too. 866-294-1660.

    FM= Frequency Modulation= Line of sight.

    AM= Amplitude Modulation=all over the map.

    Azimuth and elevation of the broadcast antenna is critical to the directionality of your antenna. That unit on the hospital may be blocked (by an old Harley) or is specifically directional or maybe even just a relay rig.

    Buddy up with a TV engineer for better poop. Finding one is usually easy or easier than trying to get into the station to talk to the weather girl with the big rack and great teeth.

    I mentioned in the original post that I tried higher on the building and SINR got worse.

    Not sure about their home phone service but I highly doubt it.

    Haven't got out the amateur telescope and looked for the antenna but I suspect it's a few feet below sight line. I also haven't done a recon of the hospital yet and checked their antenna configuration.

    The weather girls are the only thing that stops me from slitting my wrists after watching the first 20minutes of the news broadcast. :drool:

    Local IT consultant I spoke with said that amplifiers have worked well for voice but hasn't had luck improving data in his experience. Too much going through the stream and amplifying poor signal just amounts to more data loss and thus little change in speeds. That's what I understood of the conversation anyway.

    Hard to grab something that is not there. Try and do a site survey at different points on your roof and maybe other spots on your property. RF is flakey and unpredictable, Move a couple inches one way or the other can make a difference.

    I asked about home phone service at least where we are if your wired for phone service they can give you DSL.. if you make a big enough stink about it they will route service your way. kinda strange that you are in between a school , which all nowadays are wired for internet, and a housing area, also wired for DSL and cable modemss that they "skipped" right over you. tell them you want the complete package Phone/TV/internet.. see what they can do. The farm I manage I put up a little bit of a stink and they came out and did it.. just saying.... strange that your signal dropped when you raised the antenna height. pull out the old telescope and play peeping tinker and see if you can locate the hospital antenna.. like you said it may not be there thats what the internet said its location was so try looking around the hospital. hope you find it...

    I didn't say the signal got worse, I said the SINR got worse. Signal strength remained the same. It's not sounding like you're the expert I was looking for when I posted this thread. :)

    I don't want their TV or phone service. We use free antenna tv and streaming. The telecom companies claim we are too far from their equipment. I think they're full of shit and don't want to spend the money to trench a cable.

    DSL does have a distance limitation, roughly 19,000 ft from the telcom equipment. I had DSL in NY and was the last one on the line, tolerable performance, I used to connect to my client's servers via VPN and do remote administration. Before DSL, I tried the Hughes satellite system for about 9 months out of desperation, but the latency was to long for VPN.

    yeah DSL does have its limits but they do put boosters in-line... Tink I wasn't saying you had to get all the services.. but your probably right, they are just lazy fuckers that don't want to install a line... I misread your post about the Sinr getting worse not the signal. Been on cold medicine for three days makes a person loopy... hope you get it figured out...

    My DSL experience has been bad in the past. Broadband did me well and I was super sad not to get their service here.

    I'll get it figured out

    So here's the latest; still sucks.

    I tried locations all over the property and I got a picture higher up on the house just to make crusty happy

    [​IMG]

    At some locations I can see the Verizon antenna but my problem is still the noise ratio SINR. The best I've seen is -77dBm (good) and 2db SINR (awful). The antenna I purchased is a wide band yagi marketed for my modem which only reads one LTE channel and would be better served by a narrow band antenna. I'm hopeful this will cut down on the noise being picked up by the antenna. Otherwise my problem may be overloaded tower.

    My next step is to try this DIY antenna:

    I don't have it mounted yet. I JB welded the whole thing together last night. I need to attach my leads to the driven element and make my mounting apparatus today.

    I hope to know something tonight.

    Theoretically it's 16.3dBm gain designed for 767mhz which is the upper end of Verizon's 4G LTE channel 13

    Hope it works for you, definitely the best option. I used a hi gain yagi, with an amplifier to go over 60 miles for my HD digital network TV in New York, worked great.

    Hmm - Hopefully your new aerial will do the trick, but if the problem continues then you may want to turn the problem around. Instead of focusing on how to get your property connected, find some place which does already have DSL and you can see from somewhere on your house or property.

    Go visiting and see if they are interested in some sort of partnership deal to share half the cost of them having a fast DSL installed. I know quite a few people this side of the pond do this - especially if they live out in the sticks and the local telcos are not interested in running cable to them.

    So maybe climb back on the roof with a pen and local map and note down all the properties which you have clear line of sight on. Then go visit them.

    Chances are if you offer to meet half their DSL line subscription cost they will be very happy to share the DSL connection with you and even supply power for a transformer to run a line of sight wireless Ethernet bridge located on their property to send the DSL to a receiver on your property.

    OK there will also be a one off cost for the Ethernet bridge hardware and its installation/set up, but thereafter it will be fairly cheap.

    (New stuff is expensive but this sort of stuff has been around in Europe for several years now, and you should be able to find second-hand kit at far more reasonable prices, especially in areas which have been recently cabled)

    In Europe 4G LTE service is stupidly expensive and most suppliers impose additional download fees, which makes it the most expensive route to the internet.

    Good Luck.

    Skimad; that was my first thought months ago. I shied away from it due to security concerns.

    If you decide to share a DSL connection you can use an inexpensive router to isolate networks and use a unique IP schema for your network.
