min antenna distance

[ulli]

I plan to use 3 different RFM69 modules next to each other. One 433Mhz and two 868Mhz modules with a distance between two antennas of ~2cm.

I am thinking about if there is an advantage or disadvantage in the order of the modules/antennas.

e.g. 868Mhz – 433Mhz - 868Mhz     or   868Mhz - 868Mhz - 433Mhz

Do you think it does anyhow make a difference?

no proposals?
I think  868Mhz – 433Mhz - 868Mhz would be best?

If you're asking for an opinion, mine is that it should not make a difference.
Doing a real test is far better than a guess

All right, thx!
