The Francis Pre-Tuned Antenna goes from the box to the airwaves in no time at all. Quickly mount your antenna without the hassle of a long setup time. These antennas don't usually require tuning, but it's important to test SWR to ensure safe operation levels. Why?  Lack of a ground plane or other issues unrelated to antenna length can cause high SWR levels and may potentially damage radio equipment if not corrected.

    Francis Pretuned Antenna

    It's light weight flexible and great for anyone not concerned with receiving or trans mitting any kind of distance.

    Low SWR Reading

    I installed my new Francis pre-tuned antenna without complications. I located the 4' antenna on the driver side between my tailgate and taillight regarding my 2018 Nissan Desert Runner. I know the antenna was delivered pre-tuned but I did have to cut 1/2 inch off the top for very low SWR readings. I used bolt cutters which made the adjustment simple. I installed a heavy duty spring to my antenna due to my trail driving I do. All in all I recommend Francis Antennas for your cb install.

    Still a Good Antenna Today

    I owned Francis whip Antennas back in the 70's, the new one is preforming as expected.

    Francis Pre-Tuned Antenna

    We bought this antenna on a recommendation from a relative who has been for 40+ years and still is an over the road truck driver. Couldn't be happier, he warned us that it may not get quite the range that a tunable antenna might provide, maybe a mile difference is all, but is plug and play with a whole lot less hassle when setting up your equipment. He was right.
