- This video will show you how to tune a fiberglass CB antenna that does NOT have an easy tune tuning ring or tuning tip screw!
Some antennas come with an easy tune option such as a tuning ring or tuning tip. Some antennas do not! In this video, we will show you how to tune a fiberglass CB antenna that does not have a tuning tip at the top of the antenna.

Tuning an external CB antenna is critical to optimizing your CB system performance. It can also help to reduce potential damage to your CB radio! Every CB antenna needs to be tuned to it's application. If you have been experiencing poor performance/reduced range, etc. with your CB system, be sure to tune your CB antenna! You should not transmit with your radio if you do not know what your SWR readings are or if the SWR readings are outside the acceptable range as you could potentially damage your radio!

Such a beautiful sight to see it on an antenna analyzer. You want the lowest part of the "V" to be in the center of the band on channel 20.
1.3 to 1 on ch1
1.2 to 1 on ch20
1.3 to 1 on ch 40.
Of course lower is better and sometimes you have to settle for higher than what I have posted. Those number are just a realistic example.
You want SWR lowest in the center on ch20.
If you shorten the antenna too much it will resonate in the 10 meter ham band at 28000 MHz. The shorter the string the higher the frequency in music. Likewise the shorter the antenna the higher the RF frequency it will be in tune with.
Its so much harder to see with a simple SWR meter but you might can plot out a pattern by checking 1, 10, 20, 30 and 40 and draw it out on paper
Also great trip from another youtuber IMSAI Guy ! Before cutting an antenna 1st check SWR then clip with a good solid connection some extra wire on to make the antenna longer and see if SWR gets better or worse.
I've seen 5 inches have to be cut off a brand new trucker 3500 to get SWR right and its scary to do that to a brand new antenna but sometimes that's what it takes.
You have first to check wether the SWR is high on a low freq or high freq... If the SWR on ch. 1 is better then on ch. 40 the antenna is a little bit too long and you could cut it shorter. If the SWR on ch. 40 is better then on ch. 1 the antenna is too short already and should be made a bit longer. of course it all depends on where you want the antenna to be resonant. And a 1:1.1 SWR will not always get reached. It depends on many factors like how good is the antenna earth and which influencing objects are close to the antenna.
Use a little common sense, the vid show how to properly trim a fiberglass antenna. It’s not a vid on how to check SWR.
Best vid, straight to the point. ⭐️⭐️⭐️⭐️⭐️
Yooooo same pfp
I have a question , I have a road pro platinum CB antenna fiberglass . I can’t seem to get it under 3.5 it’s way to high I keep taking a little off and a little off and it just is not dropping . I don’t want to take to much off because then u get to the point of no return . Do you have any suggestions ?
What are the readings on channel 1 and 40? Read the firestik booklet on antenna tuning.
Y’all getting under 9?
Thank you
Happy To Help!
So question. I have a Francis 5.5 and my swr is 1.5 on 40 and 1.2 on 1. So my antenna is too long right ? If I wanted to use a 102 whip wouldn’t that make my swr higher ?
When using a 102 inch whip, to have the necessary length of ~108.5 inches, you should also be using a spring and if it is a 6 inch spring, you will be good to go. I could not find a 6 inch spring so I used two 3.3 inch springs and all is good.... The spring is often overlooked by many and you need the extra ~ 6 inches by a "spacer" rod or preferably a spring....

Wait up y’all’s swr under 9?
Your goal is to have the SWR as low as possible. An SWR of 1 is as low as you can achieve. You risk damage to your radio once you reach an SWR of 3 or more. You can even damage a radio with excessive transmit with an SWR of 2.5 or higher.
