This extract is part of a webinar presented by Dr Andre Fourie on 24 Oct 2017.

The following were discussed:

• Antenna Properties & Problems interpreting specifications
• Application considerations
• How to choose your antenna
• Impact on Data Rate, including MIMO
• Environmental Considerations
• Why pay for reputable, well designed antennas.

very helpful and instructional videos that gives me insight on what sort of antennas i should buy for my home network

Asking for a 'SIMO'-antenna Wifi-setup at 5, 18GHz:

Devices: Tx has a single antenna output, Rx is a RUTX50 with two antenna inputs. Setup will be used mostly in urban environment. On the Tx a directional antenna will be used, vertically polarized.

Which antennas/antenna configuration will provide the most stable connection between the mentioned devices?

1.) Two antennas are used on the Rx. The antennas are technically identical and both have a H-pol. and V-pol. in-/output. One of these antennas is used on input #1 of the Rx with it's H-output, the other antenna is used on input #2 of the Rx with it's V-output.

2.) A crosspolarized/MIMO-antenna like the WLAN61 is used on the Rx's inputs.

For 1.): If this option makes sense, will it be beneficial to distance the two antennas instead of placing them near to each other?

Thanks in advance.
