- There are two antennas on the RX unit. Try put the transmitter antenna of the RX unit, in an oposite position to the receiver antenna: If one is in vertical position put the other in horizontal, and vice versa. Match the position of the WD antenna with the position of the transmitter antenna used on the RX unit.

Hi all,

This is, by my opinion, VERY important information, the both antennas can interfere with each other!

Based on my experience, I recommend setting the receiving antenna on the RX unit with about 30°
offset from the vertical position (no more than 45°). All TX units should have the transmitting antenna
inclined in the same direction - ideally parallel should be. The intersection of the highest radiated power
must lie in the center of this RX antenna. We will use the receiving antenna on the RX unit ideally with
a bigger gain (beware - suppliers are often lying about its parameters) - about 6 dBi.

Conversely, for the transmit antenna on the RX unit we use a small antenna - 2 dBi, bend it to the horizontal
position and similarly to the antenna of the WD unit. The range gets smaller, but it could be enough in smaller houses.

But, as Werk_AG says, the right selection of antennas and their setting is a bit of ghost, a bit of alchemy ...

Good luck!
