Outside Antenna Installation on a J-Bar Mount


Warning:   These cables are VERY sensitive to bending.  They are high-gain, low loss cables and are sensitive to pressure on the inner wire which is made of aluminum. The amount of bending of the cable as it is laying in the shipping box is the MOST that you can bend it.  You cannot bend them in a V or L or kink them in any way.  Damage to these cables will require the cost of a replacement cable and shipping at your expense.


Mount the Antenna J-Bar using the supplied instructions.  This J-Bar can be mounted on a wall, an eave, or on the shingles of a roof.  All installations of the J-Bar are at your risk.  Net All Over does not take responsibility for leaks or structure damage due to improperly installed J-Bars.  If you mount it to the shingles of a roof, be sure to use lag screws and seal the screws and the J-Bar with Roof Cement or Tar Patch which can be purchased from a hardware/home improvement store.


Assemble the antenna according to its instructions that were inside the Antenna box.  You can then mount the antenna onto the J-Mount.


This antenna is highly directional. Use the map provided with the antenna kit to point the antenna at a straight line to the cell tower.


You will need to run the cables from the antenna inside the house.  This will normally require drilling a hole or holes for the 2 cables.  Do not stretch, force, or bend the cables to get the connector through the hole.  It must go in without much effort in order to avoid accidentally damaging them.  The end without the pigtail cable will go on the antenna.  You can connect the antenna to the cable and then seal it with either silicone seal tape or Coax-Seal Sealing Tape (both are available at hardware/home improvement stores) in order to prevent water from getting into the cable connections.  Moisture in the cable will degrade the performance of your antenna.

When you install the antenna inside, you can screw the small connectors on the pigtail cable directly into the LTE radio/router.  These do not have to be sealed.  You can plug either cable into either antenna connector on the radio/router.

You are now ready to test.

Cable Length

This antenna kit comes with 30 ft long cables.

If you find you need longer cables, we sell them Here, but it is usually cheaper to move the router closer to the antenna and use a Wi-Fi extender (see our blog post about Extenders Here)

This is because Coaxial cables lose signal db gain the longer they are. once you get beyond 35-40 ft, you start losing more signal strength than you gain from the external antenna outdoors.
Any cable longer than 30 ft needs to be LMR 400 or a similar low-loss variant to be effective. These types of cables are more expensive to manufacture and sell, so the best option is to use 30ft if possible.

No Internet

This section assumes you get no Internet connection with the external antenna’s plugged in, but you can o get internet connection Without the external antenna’s plugged in. If you cannot get Internet with both the external antennas and the smaller ones that come with the device, consult the No Internet troubleshooting section for your specific router:

If you just installed the antennas,
Note that these antennas are highly directional. They need to be pointed at a nearby cell tower to function properly. Consult the map that came with the antenna for nearby towers. You can also use Cell Mapper to browse towers near you

If the antennas worked before but no longer,
It is possible the specific tower the antenna is pointed is having issues. Try pointing the antenna to a different tower or waiting up to 24 hours for the issue to resolve,

If this does not resolve the issue, then the problem is almost certainly a hardware failure of either the antenna cables or the antenna itself.

To isolate the problem, look for any obvious breaks, kinks, or loose connections between the router and the antenna outside.
Try unplugging each of the antenna cables one at a time while testing to see if the internet comes back on. If it does, you know the cable just unplugged is bad while the cable still plugged in is functional.

Intermittent Internet

Tower Congestion
Keep in mind that it is normal for internet speeds to fluctuate throughout the day. You will often see slower speeds around 6-10 PM, especially on weekends, because that is when the most people are on the cell tower. The cell tower only has so much bandwidth to give out to users. If there are more users requesting bandwidth than it has available, it will give less bandwidth per user. Metaphorically speaking, the cell tower must cut smaller slices of pie to ensure everybody gets a slice. This is called Tower Congestion.

Try pointing the antenna at a different tower nearby and test speeds at different times of the day. It is not uncommon for a tower in a city to give the best speeds early morning but slow down significantly during peak usage hours, whereas a different tower might be slightly slower, but offer more consistent speed and connection.
