RoadPro RP-550 30 Inch Ring Tunable Stainless Steel CB Antenna

I am very pleased with this antenna. It works as well as any shortish antenna I have ever had, and my experience on the subject spans 60 years, most of it being a 2-way radio tech. In addition, the tuning method is the easiest I have ever encountered. I literally swapped SWR meters during the process because I couldn't believe the reading I was getting...imperceptible reflected power on channel 20. In this installation on my own car, I used an NMO hole mount and added a TRAM NMO to 3/8-24 adaptor between the mount and the antenna (I like the stability and wide footprint of NMO mounts, plus I've installed thousands). Doing some math in my head, I ran the tuning rings up about 4/5ths of the way up the threads and took a reading...it was perfect, first try. I got another meter and re-checked...still perfect. From a practical standpoint, if I had to find something to complain about on this antenna, it would be the open loading coil as they tend to "grab" tree branches and subsequently become un-coiled, but that is not the fault of this antenna, merely a downside to open coil antennas in general, and the open coil is the very feature that makes it look like NOT a CB antenna. If it gets damaged, I'll just shell out another ridiculously cheap eleven and a half bucks and get another just like it.

I bought this specifically in hopes that I could get it to tune to 29.58 to 29.68 MHz to cover a local repeater and the national simplex at 29.6 MHz. I cut just about an inch (a little bit at a time) and with the help of the tuning ring.....Yeah....it works perfectly. SWR is less than 1:1.3 across the frequencies I wanted to cover on a mag mount. A little road testing has proven it to be effective. I am pleased with it. I originally bought this to use with my backpack radio setup. I haven't done that, yet.

I bought this antenna to replace the mag mount Little Wil which had sat on my Suburban's roof for a couple of years (it was supposed to be temporary). I chose this antenna because it looks very similar to the Larsen NMO2/70B ham antenna I had already installed on the driver's side of the hood, and I wanted to mount the RoadPro in a symmetrical fashion on the passenger side. I installed it on a Firestik SS-174 stainless steel hood channel bracket and connected it to my CB radio via a Firestik K-8R18 coax cable (with Fire-Ring connector). I cut the cable to length and soldered on the included connector. It was all a very simple, straightforward process. Out of the box, the antenna was way out of tune; my meter showed 2.5 SWR on channel 1 and 3.4 SWR on channel 40. Not to worry, since tuning this antenna could not be easier--you simply loosen the two chrome rings at the base of the antenna, twist them up or down the shaft as needed, then re-snug them. It took me a few times adjusting them, but eventually I got it down to 1.1 SWR across the board (checked on channels 1, 20 and 40). Looks great, very easy to tune, and offers little wind resistance. What's not to love? This antenna is a fantastic value.

tuned up well 1 almost across the entire band. The full power of the radio is being sent to the antenna. I have not done a distance test but have got a response every time I TX from it. I expect it will be good for short distances without the look of a ridiculous cb antenna.

Very cheap. Antenna set screw and as stripped out. Definitely returning it

This antenna had a perfect SWR right out of the package. I mounted it in the center of my trunk. To me the range on this antenna is good but not great. Me and my friend tested this antenna. We could talk to each other clearly at 5 miles, and spotty at 6 miles. For less than 20 bucks in my opinion, this is a good antenna.

Works good for my Sirius radio am/fm. It won't rust like my oem antenna did.

If you need a good antenna for keeping up with the truckers while going on the highway, its perfect. If you want to work skip, not so much. But a decent compact antenna overall.

A decent cb antenna, a great listening antenna for SDR.

Da muy buena calibración de 26.695 a 27.405 mhz. Muy recomendable por el precio!

Working good

Good product

if you want a plastic based bent antenna with threads that are very loose 3/7.5x24 than by all means buy this antenna. complete garbage.
