 Martin, you do say close to the antenna so that is good.  You don't say what kind of antenna, so that make a difference.
I'm not one of those guys who is adverse to using sleeve cores, if there are enough of them.  Looking at the Laird data, they show impedance v. frequency without saying whether is predominately resistive or reactive. Because it's pretty flat, I'm guessing resistive.  In that case at HF, ten cores would give 600-800 ohm.
Many who subscribe to the idea that you need 5K or higher will disagree but I think for the average beam or resonant dipole, that is enough.  The only problem I see is that the diameter is so small.  I can't think of a cable I would want to use that would fit through those cores.

 The attached picture displays my proposed CM choking scheme around the 
antenna switch. Take a look at this and comment, please - what is 
insufficient, what is an overkill etc.
