If you took the proven features and performance of Firestik's famous KW series antennas and added a unique tuning mechanism to the top, you would own the equivalent of a Firestik II, FS Series antenna. Aside from the ease of tuning, the patented design broadens the antenna's bandwidth to keep SWR lower over more channels. The upper coil extension also increases the power handling capability of the antenna. All FS antennas are compatible with autos, trucks, vans, motorcycles and ATVs in a single antenna configuration when metallic ground plane is available. Or, they can be used in dual (co-phased) configuration on any vehicle made from any type of material. Like all CB antennas, the FS antennas should be fine-tuned (SWR) in their final mounting location. If you've ever tuned a non-tunable tip antenna, you'll have a real appreciation for the FS antennas. To tune an FS antenna, you just pop off the tip and turn the adjustment screw up or down as needed. All FS antennas exceed the requirements of any CB radio, new or old. Aside from the high-performance loading coil that maximizes the transmit/receive functions of your CB, these top-loaded antennas will also receive the NOAA emergency weather alert and national weather broadcasts for radios with those features.

The "FS" antennas are 100% American made with 100% American materials. To maintain a balance between flexibility and ruggedness, Firestik uses a custom blended, glass fiber reinforced shaft. Each is wound with heavy insulated copper wire to prevent the oxidation and shorted windings often found on non-Firestik antennas. The tunable tip mechanism is made from rust-proof brass and has a rubber O-ring to hold the adjuster in place after tuning. Our 3/8"-24 threaded base has a tapered contact point that works especially well with Firestik mounts and accessories. The tapered "lug-nut" effect transfers stress away from the threads and reduces the possibility of vibration-induced loosening of the antenna in its mount. Each antenna is covered with a static-reducing, water-tight sleeve containing UV and pigment stabilizers. For peak performance, we recommend you use one of Firestik's 18-foot Fire-Flex coax cables with these antennas.

ALL antennas, regardless of style or manufacturer, MUST be tuned after installation on the vehicle. Transmitting antennas are not "plug-and-play" devices.

Great service

They are very involved and appear to take great pride in offering the the best service possible!

Awesome!! RCR!!

I'm doing a complete system reboot you might say. I purchased a new Cobra 29ltd NW, 2 firestick fs2 tunable antennas, studs, and a procomm rg86 coax for duel antenna setup on a Chevrolet 2500hd Crew Cab. The old Cobra 25 lasted a good 25+yrs and 4 other trucks so time give her a rest. Everything is setup perfectly super low SWR on all channels and reception is top notch. I sent the radio off for some upgrades to add the finishing touches I wanted. I'll be ready to hit the road nowing I couldn't have a better setup that will last for years to come! Thank you RCR, you are my goto guys for all my future CB needs!

Excellent service and product!

I received my order quickly and the products were excellent. I have since ordered additional gear from Right Channel Radios. Very impressive.

Firestik Tuning

I had a lot of user (me) caused problems, SWR was high (3.0+) and radio gave BAD ANTENNA warning. First, I mistakenly put a star washer between the physical antenna and the mount lug causing an impedance problem.
Took everything apart. Checked coax and ground connections ,added an additional ground strap ,checked all insulating grommets. Realized my mistake and reassembled. Took off vinyl cap and was able to get SWR to 1.7. Put vinyl cap on, closed the door of the jeep, recheck SWR ,,2.75. ???? Went to Firestik website and read everything about tuning. When tuning, reinstall vinyl cap, close the doors, hood, bed covers, anything that alters the ground plane. Down to 1.4 SWR across channels 1 ,19, and 40. I suggest, strongly, GO TO THE FIRESTIK WEBSITE. And , yes, a tennis ball affects your SWR. Looking forward to many years with this antenna. On my wife's jeep Ill get the FIRERING coax and adapter. Looks to be much cleaner install.

The real thing

Nothing like the genuine Firestick. Don't trust imitations.
