Aomway Whip

Last updated 19 March 2017

This is the type of linearly polarized antenna you usually get for free with your RX or TX. It's most likely a simple dipole antenna. I wouldn't use this for FPV, but I think it's a useful reference design for comparison purposes.

Matching is OK. The bandwidth is surprisingly large for this type of antenna.

I imagine any lossy materials used in the connector or coax that change the Q may cause these to be a little broader.

And 5.8GHz do you actually see the impedance bump from the connectors?

Have you ever popped a few adapters inline to see how it changes?

Yes the connectors definitely do have an effect, especially the cheaper ones. Typically the reflected signal changes by a few percent when adding an adapter.
