Hi,
I've been hunting around for anecdotes of temporarily shortening the radiator of an EFHW and using the excess to form an RF choke, but other than one reference to coiling up a bit of extra for adjustment [1] I haven't found much.
I've got an EFHW cut for 80m. Specifically, the EF-QUAD EndFedz Antenna. I anticipate situations where I won't be able to string up the entire length. If I were to coil up the "excess" beyond, say, the 10m half-wave length (maybe even snap a ferrite core around it), what sort of performance/side-effects could I expect?

Thanks.
