We are planning to use two Aironet's 1252 over an 2.7 km point to point link.
One of the options we have it to install three HyperLink Parabolig Grid 5.8 MHz 27 dBi antennas in parallel for every 1252.
I have some concerns because those antennas are not supported by Cisco. In fact, the most gain of Cisco supported antennas is 10 dBi Yagui for 2.4 GHz and 6 dB Omni for 5.8 GHz.
The question is if the 3x 27 dBi antenna array on each side will work without self interferences and what would be the required separation of antennas to get 300 Mbps over the link.
Has anyone tried something like this with the 1252's?
Thanks in advance for any information.
