With these ferrites I ask the same question, should I put the choke close
to the 9:1 Balun or near the switching box and how many turns? some bevs
have the feed point at +- 60m away from the switching box.

Use the #31 material. Wind at least 20 turns of RG58 around it. Place it as close to the 9:1 transformer.
