Cobra HG A1000 18.5 inch Magnetic Mount CB Antenna – Heavy Duty Magnet, For use in Cars, SUVS Recreational Vehicles 100 Watt Power Handling Capability, Black

I purchased this Cobra antenna as an upgrade from the stock antenna that came with my Retevis MB1 radio, which was serviceable but very basic. This Cobra antenna considerably improved my TX and RX (I’m just pushing a standard 4W from my CB) and overall it just performs better. It is fairly easy to tune (if you’ve never tuned an antenna, it’s easy to do but research how to do it to get it right) and the magnet really sticks well. The latex boot is a great idea to protect your car.Originally I got this antenna missing a piece - the mast was gone, but Amazon coordinated a swift replacement. Nice work, Amazon.

This antenna works great and is very easy to install. Simply stick it to the top of your truck and run a cable through a window/door jamb, or through the floor. Make sure to invest in a SWR meter and use that meter when calibrating your CB radio/antenna setup. Don't be afraid to use a hacksaw to remove 1/4 inch of metal at a time from the antenna itself to reduce SWR. I ended up removing almost 2 inches of material from the antenna before achieving an SWR of 1.2 on channel 1 and 1.3 on channel 40. Plus, if one has to drive in a low clearance parking garage, you simply pull the antenna off the roof.

Worked well until it didn't. Mast fell out on I-20 thru Atlanta. Reception and range was ok but durability was not. Only had it for about 1200 miles before it bounced out. I would recommend putting blue loctite on the set screw.

One of the best magnetic antennas on the market. Great reception and easy to install. Great value for the money.

Finding a suitable antenna is crucial for optimal CB radio performance. Proper antenna selection ensures effective signal transmission and reception, ultimately enhancing communication range. Consider factors like antenna type, height, and location when making your choice. Ultimately, a well-chosen antenna significantly improves the overall user experience and communication clarity. Remember to consult the radio's manual to ensure compatibility and safe operation.

This antenna is pretty decent for the price. It does perform fairly well, I was able to talk up to ~1.5 miles away on the open road (measured using Google Earth and two separate vehicles) and receive from maybe 2 to 3 miles away (some trucks I could hear before I could talk to them, even though they were running barefoot) so the performance is pretty decent.The build quality is very nice, the plastic feels durable, the whip is made of stainless steel and painted black, the antenna is flexible, but has a base and a mid load coil. the actual plastic base where you insert the antenna ALSO has a coil in it, in addition to the one visible on the antenna. This is what dampens the effectiveness of this antenna to poor performance ranges.The antenna comes tuned for channel 1. I have two of these antennas and BOTH where tuned for channel 1 out of the box. You will HAVE to cut about 1/2 inch of the antenna (good luck) before you get the antenna tuned for channel 20. It does tune fairly easy though. Once tuned, I received SWR readings of 1.6 on channel 1, 1.8 on channel 40, and 1.2 on channel 20. Cutting this 1/8 in SS whip is no laughing matter. Use bolt cutters. Good, bolt cutters. It actually damaged my cheaper bolt cutters, rendering them useless.As for the power handling capability. This antenna should not be used on amplified CB radios or used with linear amplifiers. The base load coil (the one in the plastic at the very bottom, not the visible one on the whip) will get warm and you will feel it mildly warm if you touch it after transmitting for 30 or so seconds. It may say 100 watts, and it does handle that much, but you will not actually get that much radiated power because you're going to be losing half if not more of that power to heat and dielectric loss because of the cheap base load coil. If you go over 100 watts, you're playing a game of "when do I want to short my antenna". I deducted two stars for the heat problem even when just using a CB that swings a little large. Yes, you're better CB radios that may swing ~18 or so watts will actually heat this antenna pretty good. For kicks I tested it with a 12 watt dead key and swing of 50 watts, and it sure did get hot. Thermometer read about 90 degrees Fahrenheit, with surrounding air at 55 degrees, at night. You have been warned.Besides the fact that the base load coil is markedly cheap and hardly handles 100 watts safely, the construction quality is excellent, the plastics do not feel cheap, the whip feels sturdy, the coax is 18 feet long, RG-58/U flexible, the PL-259 plug on the end is decent quality. Easy to tune, easy to use. The magnet holds strong even going 75 MPH. Not ugly, and easily hidden. However, get the Wilson Little Wil if you can, it can actually handle more power, and doesn't get warm, plus, it works about 200% better than this one and is only an extra foot and a few inches of antenna length.

Compramos esta antena para el camión de mi esposo, y hasta ahora ha funcionado muy bien. La instalación fue sencilla y la calidad del material se siente resistente, ideal para el uso rudo en carretera.La recepción mejoró bastante en comparación con la antena anterior, y se nota la diferencia especialmente en zonas donde antes había señal débil. También es compatible con varios modelos de radios CB, así que no tuvimos problemas con la conexión.Es una buena opción para quienes necesitan una antena confiable y duradera para su camión o vehículo de trabajo.⭐ Opinión honesta. Lianet.

So I purchased a handheld CB for emergency purposes, and I also purchased this antenna. I must say, this antenna is amazing in quality and range. It allowed me to talk to trucks from my university campus all the way across the river, out to US-22 where the Lehigh Valley mall is. That is some incredible range considering it is hilly with lots of large metal buildings around.Anyways, I recommend this antenna to anyone with a CB, even a handheld. I know many people purchase a handheld CB for emergencies in the car, but many people don't purchase external antennas. Note to all of those people...having the CB in the car will diminish the transmitting range to almost nothing. Besides, if you have an emergency, do you really want to stand on top of your car and call for help b/c your manufacturer supplied antenna is a piece of junk? While pulled over you could set this antenna on top of your car and call for help. Or, whenever you are driving on a long trip, put it on top of your car ahead of time. It's also great for killing time and talking to people. I also purchased the Cobra telescoping antenna for true emergency purposes if I am separated from my vehicle and far from the high-way, I need to reach someone etc.Overall...good to have...and it works on highways going over 80mph!
