RG-393 is pretty stiff to wrap around a ferrite. RG-142 is good for over
3KW average power on 28Mhz and below. The PEP/CW rating is higher do to
less heating. This is well above the rating for RG-213 that I use for my
antenna lead.

First, why is 393 a requirement? RG142 silver center/double silver braid
is rated 2000w at 50Mhz. I've been using 142 for several years at QRO in
240-31 wound chokes and not had a problem. Then the big snap-ons will fit.
I use the big box plastic junction boxes, Carlon or Thomas & Betts. 4x4x4,
6x6x4 and 6x6x6 are large enough depending on the core count.
