Solution to setup an antenna at a
sweet spot running a long coaxial cable

Signal attenuates in the presense of obstructions such as wall, trees, building and a concealed in-house WiFi hotspot without an external antenna. A sweet spot is a location where you have a direct line-of-sight towards the signal source. It makes a difference in signal reception if you are able to setup your antenna in a sweet spot with minimal obstructions.

Sometimes a sweet spot is near a far corner by a window or at an attic overseeing the remote Wi-Fi hotspot. You may also need to mount your antenna on a mast for best signal reception.

The problem would then be running a long RF coaxial cable with so much signal loss that completely offsets the signal gain at the sweet spot.

For instance, the signal loss of a 50ft cable RG-58 is 16.1dB at 2.4GHz. If the antenna gain is 18dB, it could be reduced to 18dB - 16.1dB or 1.9dB.

So the solution is to eliminate the RF coaxial cable by using the Catch n Share Repeater to work with the 2200mW NextG USB-Yagi TurboTenna, so that it extends digital signal over the Ethernet cable that could go as far as 1000ft without signal loss.

You could terminate the Ethernet cable on either a computer or the WAN port of a 802.11n or 802.11ac router that you could establish as your in-house hotspots for sharing the Internet with phone, touchpad, notebook, macbook. See above diagram for reference.

Some buyers reported that the signal strength was further increased by installing a wall mounting kit at an elevated level rather than setting up the antenna behind a window. The USB amp was removed from the Yagi and kept indoor with the use of the 6FT RF cable. Lightning arrestor is strongly recommended if the Yagi outdoor mounted outdoor.
