These antennas appear to be available ONLY in RHCP. They are also only available in four-lobe versions, but honestly, I think that's not a big deal, and it keeps things simple with having spares. The four-lobe antennas have better polarization anyway.
UPDATE: These antennas are awesome. You need to put a cover on them or they will break like anything else, but overall, their performance and reliability are excellent.
