Extend range with alternative antennas


Recommended Posts

Hello,

my aim is to extend the standard range of the tetra pineapple. Target is on a specific direction.

I have read the specifications of the TETRA:

“Wireless: Atheros AR9344 + Atheros AR9580, both IEEE 802.11 a/b/g/n with quad integrated skybridge amplifiers and included 5 dBi antenna for a high 29 dBm gain EIRP Ports: (4) SMA Antenna, RJ45 Fast Ethernet, Ethernet over USB, Serial over USB, USB 2.0 Host, 12V/2A DC Power”

1) Would two of these antennas extend the range of the TETRA directional significantly? Of course I would replace the two wlan1 antennas (the two on the right side when the front side of the TETRA is facing you).

2) Would two of these antennas extend the range of the TETRA omnidirectional significantly?

3) Is it right that I will need these RP-SMA to SMA adapters additional to the above mentioned products?

If I got it right higher dBi most of the time leads to higher dBm and therefore extended range. Please correct me if I am wrong. Thank you.

If you want better directional range a patch/panel style antenna is a good choice as well as yagi antennas.  There is no need to change you management AP antennas if you are near the device.

Alfa antennas are usually good options.  Just remember you usually get what you pay for.  There are several "cheap" yagi antennas out there that have worse reception that a 5 dBi omni...
