I like helical antennas, folks. Broadband, mechanically reasonably easy to make, rather compact and can be even made without large backplane (backfire helix). Catch both vertical and horizontal polarized signals which makes them good for scanners and resistant to polarization fading (important for satellites)
For terrestial work, circular polarization doesn’t seem to be extremely common. Would it be a bad form to use circular polarization at UHF for simplex, or to hit a repeater?
