Polaplexer ?
What is Polaplexer ?
“… The Polaplexer is a microwave antenna, or antenna feed, which supports two
simultaneous inputs or outputs that are independent and isolated from each other by use
of orthogonal (at right angles) linear polarization. The isolation can be as much as 30 -
35 dB. Its main use is to permit full duplex operation with a single antenna, in which one
port is used to transmit and the other to simultaneously receive. As long as the transmit
power input to the Polaplexer is limited to 100 milliwatts or so, the receiver input stages
are unlikely to be damaged by the transmitter’s continuous output. …”
I never met this thing before it just came out from no were ! If anybody was tried this please post a comment.

For me is interesting can I use two wifi cards working on different channels with one antenna and this thing?

This VERY INTERESTING system are not suitable for wifi sistem standard because only one antenna can transmit and the other only can receive. The common systems found in 802.11 systems can’t split RX/TX system!!!

Thank You for comment.
Yes common can’t - You can use mikrotick nstream2 and use 2 wifi cards - one to RX other to TX only - and they can be set to different but not overlapping channels in same band.
So this device is really interesting and need to be tested.

what about mimo and 802.11n ?
