Re: [Hackrf-dev] What kind of antenna to use?

2018-02-05 Thread Chuck McManis
To add to what Paul said, there are many books written about antennas
because they vary significantly from application to application. Most
people start with the frequency range they want to cover, then directional
or not, then how much gain they hope to get from the antenna, active or
passive, and what sort of bandwidth they are going to be looking at.

That said, pretty much any antenna can see any signal at least a little
bit, so something like the ANT500 is fine when your just noodling around
the various parts of the spectrum.

You're not pumping out a ton of RF energy and concerned with matching and
balance here. The best best it to get a telescopic antenna that you can
adjust/trim for the proper wavelength you're using on the fly:

It would depend on the application (transmit and receive?) and frequency band. 
There is no one correct antenna.
