E field antenna height
#2
There is no lower limit for the height of the E-field antenna - If the antenna stood far out on a grassy field, it might be a few cm above grass height.
If it is to be able to "see" far omnidirectionelt, it should be just above the highest point (ideally)
At the top of a mast is very fine, but it may also be a piece down the mast - If metal mast, do a space of 10-15 cm from antenna to mast.

Do not compare the E-field antenna with a radio/television antenna, which can only see just over the horizon. E-field signals are more tolerent.

An electronic weather station sends pulses and not only DC signals. Although these are at a low frequency, the switches can generate interfering signals.
You can create a temporary setup where the antenna comes near the anemometer and wind direction indicator to check it out, before you set it up permanently.

Ferrite antennas in a horizontal cross on the ceiling is really good as long as they are kept as far away from electrical installations (preferably more than two meters)
It need not be NS / EW but it is practical to do so.

Distance between WiFi units depends on the situation - you can not not say anything specific about that.
It is not difficult to test, because BLUE just need 5 volts to operate, so it is easy to move around during the test.
