Thanks heaps for the recommendations Struthian its greatly appreciated. You got me thinking now and I am thinking maybe two of the amplifiers might be a good idea. When playing with kali with my usb wifi I have had low signal strength issues at times which can be frustrating.
So with this I would rather start off with added stronger wifi connections.
I was just reading and if I went with two of the https://hakshop.com/collections/wireless-gear/products/long-range-wifi-kit as you recommended, I could just buy the Tetra basic rather then the Tetra Boost yeh? As with that link it includes......
ALFA WiFi Amplifier
5V, 1A USB Power Cable
RP-SMA 5 dBi Dipole Antenna
So I would not need the https://hakshop.com/collections/wireless-gear/products/ralink-rt3070-usb-wifi-adapter that comes with the Tetra Boost version would I? Or is two of those needed in conjunction with the Long Range WiFi Booster on the 1st link?
Thanks again for your input mate, I will hold on ordering for another day till I sort this out.
