Looking for a TRUE 5-6 mile capable antenna to pull in internet from our town 5 air miles away. Couple trees in line of sight but antenna will be on a hill tower 450 feet higher than the town. Anything available for actually grabbing a signal that far?

This referenced product can transmit over long distances like that but a unit needs to be installed at the point of signal source. We do not know of any device that can simply capture signal from that far away without posting a transmitter at the source signal. If you do find one, and it works, please let us know. Thank you.

Question re: the size of the radio beam making the connection. I can create a line of sight corridor in a stand of the trees. The space would allow the two antennae to "see" each other without obstruction and without branches that would wave into the space. The distance is 250 feet. Is this sufficient?

Yes, that should suffice, based on info you have provided and we perceive to be the case.

Do these get affected by weather or humidity? If so, how severe is the signal loss? I would only have them at 200-250 feet away from each other.

Yes, the wireless connection will be affected by rain, snow, etc. up to 40% depending on the density or amount of saturation between the two points. Fortunately, the weather will not affect much for your intended purpose because the distance you need wireless connection over is comparatively very small.

I’m interested in extending my WiFi to our shop around 300 feet away. I looked at the WiFi PTP bridge link connection extender signal booster. Is this all I would need to order? Meaning is everything included in this package to get this done?

Yes, that is right. Everything needed is included.

Can this system be modified/upgraded/augmented to support point to multi-point wireless internet? What does that do to internet speeds?

Yes, you can configure this kit to use as PMP. However, you will need to configure the driver mode as "TDD" on both sides. Instructions provided at link here in Q & A response: (may not show in email response brief you receive)

Instructions show the basic configuration required to form a link between the AP and multiple SMs.

These radios are capable of providing the throughput of 200 Mbps which totally depends on the channel bandwidth, distance and number of SMs connected to the AP. While ePMP Radios can deliver maximum up to 200 Mbps, please note that Internet transmission will be distributed among all the clients connected to the AP causing speed degradation based on link condition, distance etc. and therefore Internet speed cannot be predicted with any accuracy. In most cases, the reduction is negligible if eliminating/discounting all external topographical factors.

Is any wireless license or wireless registration required to operate this wifi projecting system from one building to another?

No license needed and no registration required to use this unlicensed wifi point to point (P2P) projection system.

What cables do I have to supply to complete the installation?

For the building that has wifi network, you only need an ethernet cable to connect to the router (however long needed to reach your wifi source modem or router).

For the building receiving the wifi network, a cable is needed to connect to the POE switch (included) or to any other power source to power it up using any other way you can, to provide power to antenna.

A POE switch is a network switch that has Power over Ethernet injection built-in. Simply connect this network device to the switch included which will detect it is POE-compatible and enable power automatically.

POE Power Supplies for Both Wi-Fi Antennas are included with this purchase.

Is there a 2.4 Ghz version available?

Sorry, we do not have this in 2.4 Ghz frequency version. It only supports frequency range between 4910 - 5970 MHz. We recommend using 2.4 GHz Dish Antenna which supports 2.4 GHz frequency but since it is not a wifi bridge kit, you will need to purchase 2 units and configure one as Access Point and the other as a Subscriber Module. Please feel free to reach out to us for any configuration assistance.

Looks like the radio module only comes in one color; white. Can it be painted and is there a certain product it should be painted with?

Yes, they can be painted but: A) The paint must not contain any metal or metallic flakes. B) It will void the manufacturer warranty unless that paint can be removed completely if it ever needs to be sent for repair under its warranty within its warranty period.

I have purchased this product. I'm extending my house wifi to another building about 100 yards away. The house antenna will be connected to the router. What is needed in the remote building? Just a regular Access Point to provide wifi in the remote building?

That is correct.

Do these P2P bridges support 802.1Q, for vlans?

Yes, it will support 802.1Q.
