quadrifilar helix antenna - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Hi,
Does anybody out there manufacture an L-band quadrifilar helix antenna?
I need to buy one. Soon!
Thanks.
Marcus

Well, of course. They use them in GPS receivers, for instance, which is right in the middle of Lband.

Try searching for GPS quadrifiler antennas, and call the companies that pop up. I suspect they will be narrowband antennas, though.
