Wouldn't a ferrite work better?

I think ferrite is a good choice too, but based on some other posts
I've seen here, you apparently need a whole bunch of them to work
really well (like, dozens or more). Maybe a combination of both
methods would be workable for some. For me, and considering that it
didn't really need additional weatherproofing, the coax coil worked out
as a good solution for 11 MHz and up. Cost a bit less too.
