This just in — Signal Stuff has released improved Signal Sticks which are 36% thicker and less floppy! The old ones work great, though, and they are clearing out the old stock of SMA-F antennas for $15 each. Get ’em now! (choose “dual band”, “SMA-F”, and “1st Gen” to get the $15 clearance version).
All orders going forward will get the new and improved thicker wire antennas!
Thanks, Signal Stuff!

What is the swr on the signal stick?

Please see https://signalstuff.com/wp-content/uploads/2016/05/g.png for an SWR chart. Note that for a 1/4 wave antenna the SWR will vary *a lot* depending on what you are using it with — this is typical of HT antennas. Testing SWR accurately requires a special setup which isolates the antenna from the feedline, so don’t expect to get reliable results just plugging it into an antenna analyzer — every antenna analyzer will give you different results.
See https://www.youtube.com/watch?v=3Qve78EwXjc for a youtube video where SWR of different antennas were compared (by parties other than Signal Stuff).
