Minimum distance between H and F antennas

[ohifra]

Good evening, I contact you because I want to know what is the minimum distance between the antennas H and F.
Thanks in advance.
Greetings

The E probe should be outside, ,pimted verticaly, at leat a half-meter away from any metal pole mount... as far from any noise sources, buildings, and obstacles as possible,at least two-three meters above ground, and not grounded to anything... other than that, put your H anywhere away from noise sources.

Thank you so much for your reply
