[RFI] clamp on ferrites at Mouser

[Jorge Diez - CX6VM]

Thanks Jim!

So finally I will use LMR-240-UF

Will order round cable snap-its 

Seems that part number 0431164281 will be loose on the coaxial and will not
be held near the connector

Anyone tried part number 0431173951 with LMR-240-UF?  Will close on this
cable? Will be very bad if I buy a lot of them and then I see that don´t
close. 

Thanks,
Jorge

We put chokes on these cables so that they will not radiate trash on our ham
bands, so it is OUR frequencies that determine the chokes. For example, if
we want to kill RF noise on 40 and 20M, we wind the chokes for those
frequencies.
