Reply To: Space diversity


Hello RK,

I cannot find these antennas in Andrews catalog, Kathrein catalog or RFS catalog… what I can find is dual-dual polar antennas (called also “quad” antennas in Andrews), which are actually two dual polar antennas, side by side, within the same radome.

These two antennas have the same polarization and the same frequency band. I guess they provide two crosspolar with a little bit of space diversity… so it can be used for 4RX/2TX DIV. But IMO i’d use that to avoid combining 4 TRX onto one Xpol antenna. I could transmit 2 TRX on one antenna, and 2 TRX on the other antenna, that avoid a loss of 3 to 4 dB.

What do you think ?
