COAX with integrated RFI Choke · Coax & RF Connections
A coaxial cable, connector, adapter, choke, or RF interconnect.
Why operators make room for it
A carefully chosen antenna can still be undermined by the wrong connector, a strained cable, unnecessary loss, or common-mode current on the feed line. CHA COAX with integrated RFI Choke combines a selectable RG-58C/U feed-line length, PL-259 connections, and common-mode current control at one end, reducing the number of separate RF-path pieces an operator must deploy and manage. That preparation gives the operator a cleaner, more dependable feed-line plan while keeping connector, loss, frequency, power, routing, and weather limits visible.

"Only a co-ax cable with ferrites at one end but what a cable! Beautifully made with the highest quality components. These are my go-to choice for DXpeditions. They work reliably, are light and flexible and haven't let me down. Why did I need another? Well, I left on on Grenada with a local ham who was delighted to have it."
"Will deploy in Oct. for POTA excursion. Having delighted in my use most Chameleon Hybrid Antenna pieces, I am confident that this cable will work as advertised."
"This product from Chameleon was very good quality and exactly what I was expecting! Thanks!"
"Excellent quality."
"Just opened the box. Looks as expected from Chameleon. . . perfect. Sure it will work great too when I get it all hooked up."
"Needed new coax for my Chameleon antenna set up and this fit the bill! Tight, compact, fits in the backpack and WORKS!"
"These coax cables are fantastic. I needed a 75 foot for special use and they have low signal loss."
"Good quality coax and having the choke is a must for these systems. Bery efrective with 5 ferrites in line!"
"Quality has a price. It’s not the cheapest coax out there, but do you really want to run your rig with cheap coax? Chameleon products are as worry free as it comes."
"Quality equipment!"
