This might be some of the most amazing footage I've ever personally captured.

Really! Really! Great video. Second only to your old "Godzilla for Hire" series. BTW you still owe the internet a new episode.

Dan

That's awesome!! I cant wait for you to post it on Facebook so I can share it. :-)

Bob van der Vleuten

Damn that just made my day. Will the footage that appears in American Idol also be posted to Patreon?

Twisted Haywire

this is really cool. could you move the drops up and down changing the phase of one the signals. ? I would think you could, as that would move the position of the standing waves. also wat was the amplitude of that signal ?

Tim Norman

Very cool video. Loves those explosions.

dm_nimbus

Exploding frisbees of water!

Dan Bell

Awesome vid and love my 2 Ford's!

Really, really cool. This is a GREAT way of visualizing something that radio operators have to consider every day: VSWR (Voltage Standing Wave Ratio). With VSWR you're dealing with RF frequencies that are reflected back at a transmitter due to an impedance mismatch on an antenna at the end of a feed line. So instead of the power that should be going to your antenna that power (or some portion of it) comes right back at you, creating standing waves on the feed line like you see here in the video. Since AC power (really any frequency) can be shown as a vector, you can "do math" on them. In this scenario, you've got nulls in between two opposing vectors that are *in phase* and the peaks and valleys are added together and grow accordingly. In the radio world, you're dealing with kilo-volts being sent down a coax feed line and if you send down a kilovolt and let's say, 70% of that power is reflected back to you in-phase, those spikes can exceed the voltage rating of a cable. So instead of a drop of water exploding as in your video, this voltage spike can burn through your coax, cause fires, damage equipment, and otherwise ruin your day.
