Starting again with combining 2RX 9circle array's

07/01/2025

 

I have done this test before (2021/2022), but then I started renovating and did not elaborate further.

We have built up some experience in the meantime, and what I then noticed was that I did not get the same gain on both systems.

That's why I want to test this again, but now with 2 completely identical systems from antennas to the combiner.

The above photo of Eznec is the intention... 2X RX9 with a distance of 100m apart. I have done many tests in eznec over the distance from 40m to 250m and the 100m was the best version that eznec showed me.

Above are the differences between the combined (black) and the single RX9 (blue)

We will test whether the complexity of this system is worth it.

Fortunately, due to the many tests I have done in the past, I already have a serious stock of parts and the costs for this test are reasonable.

If this works like this, which has already been my finding in the past, I will look into making a variable phase shift between the two.

I haven't been able to simulate this in Eznec yet... Eznec isn't the simplest thing out there either.
