BRIEF: Low-cost money saver, Lightweight, Moderate power handling, Flexible fiberglass whip
DETAIL: Road Pal is the performance leader of low cost replacement CB antennas. We created the perfect mixture of cost effective materials, quality workmanship and antenna expertise that you expect from Firestik. If cost is the issue, you don't have to settle for cheap replacements and knock-offs. You still have the option of an affordable Firestik-built antenna at a price that will save you money and fulfill all of the basic requirements of your CB. All "RP" antennas are compatible with autos, trucks, vans, motorcycles and ATV's in a single antenna configuration when metallic ground plane is available. Or, they may be used in dual (co-phased) configuration on any vehicle made from any type of material. Like all CB antennas, the "RP" antennas should be fine-tuned (SWR) in their final mounting location. The loading coil on all "RP" antennas is easily accessable for precise SWR adjustments. All "RP" antennas exceed the requirements of any CB radio, new or old. Aside from the carefully designed 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.
All "RP" antennas are 100% American made with 100% American materials. To maintain a balance between flexibility and ruggedness, we use a custom blended, glass fiber reinforced tube. Each is wound with double insulated copper wire to prevent the oxidation and shorted windings often found on non-Firestik antennas. Our 3/8"-24 threaded base will fit all Firestik and RoadPal mounts and accessories. Each antenna is covered with a static reducing, water-tight sleeve containing UV and pigment stabilizers. For peek performance we recommend that you use one of our Fire-Flex or RoadPal coaxial cables with these antennas.
All "RP" series antennas are factory bench tested for resonant frequency and overall quality.
And don't forget ... ALL antennas, regardless of style or manufacturer, MUST be tuned after installation on the vehicle. Transmitting antennas are not "plug-n-play" devices.

Hard to install as instructed.
Size: 32 oz
Nearly impossible to get it in the tire through the valve. Yes I removed the valve core.
Broke the bead on the tire and dumped it in. That worked great! So far no leaks.
They should definitely redesign the installation method.

Been using it for 15 years! Not sure where the Neg reviews come from?
Size: 16 oz
I've been using Liquitube since around 2010. I use it religiously in my ATVs and lawn tractor tires. Since I've been using this stuff, I've never had a flat before. I've pulled out nails and slivers of steel out of my ATV tires but yet none of them lose air or go flat.
I think some of the negative reviews come from improper use of the product or not enough of the product is being used in the tires. I think this come from variance in formula charts that Liquitube has had in the past on their bottles and on their website. The chart on their website wouldn't match the formula that was provided on the bottle. So I think alot of people get mixed up and not knowing the correct amount to add to each tire. Now Liquitube just puts pictures on the side of the bottle with an ounce measurement below each picture to tell people how to use it. But even that can be confusing. For instance, take the picture of the ATV that they show. Below the ATV it says 32oz. Now some people probably think the 32oz is for the entire ATV. Well that isn't the case. They want you to use 32oz Per Tire! Years ago Liquitube even used to say on the bottle to use 32oz per tire on an ATV. Now they just show a picture with an amount below it.
Now you'll come to find out that the 32oz they recommend doesn't match up to the formula they tell you to use to calculate how much each tire is supposed to get. So if you use the formula provided, you come to find that it calculates out to use less product per tire than what the bottle tells you to use. So that's very confusing as well.
So if you use it long enough, you'll be able to know how much each tire will need from experience. Just make sure there's enough on the inside of the tire to coat the entire inside as well as leaving a bit left over to circulate in the tire so it can be ready for a large puncture if that ever happens.
All in all, it's a good product that does what it claims. It lasts for as long as the tire does and it doesn't freeze up in the cold either! 5 stars!

I literally watch my MPG jump up .3 within one tank, my mpg count after 6000 miles was steady at around 26.5 and after using this stuff and driving around for 1 tank of gas, it jump up to 26.8. I'm literally impressed!
