Radiopopper PX review part 2 – range testing

As promised, part 2 of my Radiopopper PX review. (PART 1 HERE) Although for my purposes, I can’t imagine I’d need to trigger my slave strobes from >100 feet, I figured why not push them a bit and see how far I could get before they started to flake out!

I set up 2 strobes with PXs in the windows of my 3rd floor studio, and walked outside.

Across the street. Click. no problem.

Ok, let’s try around the corner [click], yup, still firing…


Unfortunately, due to the angle of the streets I couldn’t get *too* far before I lost sight of the windows, and couldn’t verify if there was a flash or not.   I walked into the park, getting as far as I could while still maintaining LOS to my studio.  I would estimate it was about the length of a city block, maybe more.  -click- I had to check the image, zoomed all the way in, but sure enough the flashes still fired.

img_4833Probably can’t see it in that pic, so here it is zoomed in and cropped.


I rattled off a bunch more frames, and as best I could tell it still fired every time.

Finally walking back I tested out the HSS functionality.  Across the street at an ambient-killing 1/8000:

Conclusion:  In the end, I broke before the RPs did.   I actually wansn’t able to get far enough away to make them misfire – even in what I’m sure is a heavy RF interference environment (downtown Philly!) Even though I’ll probably never have a need for this much range, it’s good to know I have it on demand 🙂

Now I just can’t wait for my JrXs!

  1. Actually, you would be surprised at how little radio interference there actually is in this world. For a signal to actually cause problems it would have to be very powerful and at or near the same band. What does cause interference is electrical wires and metal walls, or solid objects in general. I would love to see a test where you placed walls between you. It the same reason your personal wi-fi is bad when the router is on the other side of the house, but you neighbors rocks because it’s in the window across from you.

    1. Good to know Stephen! Guess that’s why I’m a photographer and not an electrical engineer 🙂 They do test reliably from one end of my studio to the other, which is about 80-90′, with a wall, kitchen and bathroom in between the TX and the RX. Without any point of reference, I feel that’s pretty good…

  2. Yeah, I used to be one. Now I’m a photographer. Good to know you got a wall test. That’s where I need them for. I do a lot of real estate photography and I hide flashes all over the place. I use long cables and hide them well. I need to get me a couple of these.

  3. Thanks for the review. Currently, we are using Pocket Wizards now and are considering different triggers and options for our flashes. All your research helps!

    Thanks for sharing,


  4. Excellent test. I can’t imagine why I’d need to shoot from a block away, but it is sweet to know that I can!

    Reviews like this make me really lean toward the RP system.

    Thanks for the info.


  5. PLEASE help me with this troubled question (I’m italian and my English is fairly poor).
    I understood the use of Radiopoppers with the Canon system I own (Canon 5D and 2 580EX-II units) but could not find a technical support for using them with my Hasselblad V system AND the Canon flashes above.
    I need a remote control that works (and has the connectors) for both systems. Do the Radiopoppers work with my 553 ELX/503 CX and 580EX-II in manual mode?
    I think you are my only chance to have a sure word…
    THANK YOU for your time if you can/would answer me.
    Best regards

  6. That’s an amazing range! on that note, I was a Cellular Tech for 4 years and I know the real dangers of RF, I had a couple of RF burns in my hands as result of getting too close to the source. Don’t you think RP are emitting a little to much RF power for our own good? I saw a clip on youtube having the PX to fire at 650 feet, do we really need that range?,…. maybe its safe, FCC aproved it so it must be all good 🙂
