Testimonials
“We had somebody walking towards us, we couldn't have the pack on their front so it had to go on the back. So quite a lot of body absorption of the RF. We put on a Foamie Flex to keep the aerial tip clear. Fantastic change! We were getting break up all the time, even quite close, but then with the Foamie Flex that little bit of spacing gave us a few more dB. Saved the day!”
“These are great for preventing potential RF loss when a whip antenna touches the talent's skin. The Foamie Flex creates a separation between the antenna and the person who's wearing the transmitter, therefore the signal transmission is more consistent. Also a few actors said they liked having these on because they are soft and comfortable to wear.”
“Decent to have around for moments where an antenna is tucked tightly against a body to help with RF range & also to give comfort to talent if they are complaining about an antenna poking them. Not too thick that it'd bulk up & make an antenna more visible to camera (and most likely if it was, the transmitter would also be clearly visible).They stay on tightly to aerials so won't be likely to get lost when talent demic themselves (when I used to use foamies for the same function, they would slide all over & usually get lost very quickly), bonus that you can cut them to various sizes to use for various other applications.”
“These are a game changer for RF signal and I’ve also found them useful for putting on an antenna when working with children when the aerial needs to be against their skin.It helps keep a strong RF signal, is low profile but importantly it’s really soft so if you’re working with a child actor who is in a bit of a bad mood, it’s one thing they can’t really complain about! I’ve also used them successfully when I’ve rigged the transmitter on an ankle strap to help with the signal.I used them last year on a job about marathon runners who ran for long distances (sometimes out of range of our antennas so onboard recording was a necessity), and it really helped to keep them in range for longer.Also, the fact you get 4 for £18 means they’re only £4.50 each so you can get more for your money on a consumables order!”

FAQs
What is Foamie Flex used for?
Foamie Flex is a flexible RF antenna saver that spaces wireless antennas off the body to reduce detuning and signal loss, improving RF reliability during use.
How does it improve RF signal?
By creating a gap between the antenna and skin/clothing, it helps prevent signal detuning and absorption that can weaken performance.
Can I cut it to fit different antennas?
Yes — the foam can be trimmed to length to suit shorter antennas or specific placement needs around costumes.
Will it slip off during use?
Foamie Flex fits snugly over whip antennas and is designed to remain in place even during movement and performance.
Is it comfortable to wear?
Yes — the soft, lightweight foam is comfortable against skin and under wardrobe, making it ideal for extended sessions.
