[TowerTalk] 1/4-1/2 wave nonsense summary

[Pete Smith]

...This started when I addressed the *potential* problem of using long
>lengths of *coax* cut to 1/2 wavelength multiples.

Indeed, and straining to get back on topic ...

When I was designing my station, several smart people advised against using
multiple half waves of 75-ohm hardline to my 50-ohm antennas because the
wide frequency excursions on 10m would result in bad things (though I don't
recall that SWR bandwidth reduction was among them).

I decided to try it anyway, and all I can report is that the SWR bandwidth
of my Force 12 C-3 at the shack end of the 220-ft feedline run is within
spec on 20-10 meters.  Had it not worked out, a couple of UNUNs were wound
and ready, but the cores and wire will now revert to other service.
