    Great Antenna

    Pros

      Comments about Cobra® 21” Magnet-Mount 100W CB Antenna:

      Great antenna with a coax that is long enough to allow installation with out of the way routing and an antenna that is short enough to not hit on everything you drive under. I can actually drive in and out of my garage without it touching. I bought one and liked it so much I bought two more for my other two trucks. Good range and performance out of the box.

        This is not a quarter wave antenna that most mobiles use, it's not much more than a walkie talkie antenna.

          Comments about Cobra® 21” Magnet-Mount 100W CB Antenna:

          Been using CB radio for 30 years and ham radios for 20 years.
          I have had to buy approx 20 Mobile CB antennas over the years.
          The smaller ones usually don't get any highway distance. The larger ones are a nice flag to criminals that a CB radio and possibly more items are in my car.
          The first day I connected it to a cheap, very cheap, low sensitivity, mobile CB. Within a few minutes was hearing transmissions from miles away. I was amazed.
          I wouldn't leave home without this antenna connected.
          I am amateur radio operator and wish I didn't sell my 10 meter radio, because I really want to try it now on 10 meters. Radio shack used to sell awesome Amateur Radio Equipment, but the ham antennas were low quality. I sold my old and extremely durable 10 meter Radio Shack radio because of the lack of good-small mobile antennas. Wish this existed a while ago.
          It's nice to pull into the garage and not hear an antenna scrapping the garage door.
          Radio Shack needs to get back into Ham Radios again also. I miss the old Radio Shack stores which had lots of equipment in stock.

                  If you are looking for a decent CB antenna that will allow you to drive into your garage, then this is it. After you tune it the SWR's are around 1.5. This is great for a low profile cellular look a like CB antenna. More then adequate base magnet.
                  I am completely satisfied with this product both in price and performance. Thanks Cobra, you still got it!

                    This thing is great. I wouldn't listen to the other reviewer about getting 100 mile range. As far as SWRs go this thing was perfect out of the box. I it was around 1.2 on all the channels. I have managed to get it to go 10 miles easy and still keep a clear signal. Overall a great antenna if you don't want a bulky one.
