Sometimes it's an antenna article.
Designed by KE4ERO, this is a novel antenna for VHF and UHF bands.
It's very tall and skinny.
So it doesn't stick out as much as a beam might.
However it's horizontally polarised and exhibits some gain.
That's makes it suitable for VHF/UHF SSB operators, especially those in areas where most stations are in one line, eg up and down a coast or valley.
