Log periodic antennas are wide-band directional devices, suitable for signal hunting or simply wide-band communication. Their gain isn’t impressive, this one is rated to about 6dBi, that’s the price you pay for bandwidth.

The commercially made are really expensive, literally an order of magnitude above this eBay unit which was about 60$. But I suspect they have a similar PCB inside anyway 😂🤷🏼‍♂️

So how well does this unit perform? My #nanovna_v2 cuts off at 4GHz but starting at about 700MHz, it surely delivers a reasonable match below SWR 1:2 (620MHz for SWR 1:3)

I’ll have to bring it to the lab at work to test the upper frequency limit 🙂 For now, let’s go signal hunting! 😎

#EmacsTip: Do want the power of Emacs in your shell? Enter #ShellMode, a specialized mode for command shell. It allows you to write shell command, run Emacs commands on your incomplete shell command and output. Before you say that it isn't a proper terminal emulator, I would like say, it is! With #Coterm, you can run any full screen terminal program in #ShellMode.
