Will Coiling Your Coax Change The SWR Or Damage Your Radio? Is Coiled Coax Bad For Your Radio?

For years the online "experts" have been telling us that if we coil up our unused coax cable it will damage the radio by creating a high-SWR . In this video I test that to see if the "experts" are right. I test two types of coax, one very low quality, inexpensive coax cable, and a higher quality LMR400 coax cable. I test both using a prototype Wouxon KG-S88G GMRS radio (because thats what I had laying around) at 4 to 5 watts.

THIS IDIOT DON'T KNOW WHAT HE IS TALKING ABOUT

[@TheNotaRubicon]

With all of the data and details explaining exactly how I " _don't know what I'm talking about_ " that you have provided, I'm sure that nobody is going to point at you and laugh. PS: You should look into fixing your Caps-Lock button and maybe check into investing in a grammer-checker.

[@ERICLSTRUNK]

Says the grown man typing in all CAPS... At the legal GMRS wattage we're using, "SHEILDED" cables don't act as a choke. At least not enough to measure with the sensitivity of general equipment (SWR or RF meters). Working as an electrical engineer in the industrial field, we coil RF cables all the time with ZERO adverse effects.

[@W5KJD]

That statement by its self, (as it is) makes you sound stupid.

When a cable is shielded well enough, one would't expect any difference in SWR. And you proved it in the test. Great video.

[@risbill1]

All I can say is that I worked with everything from HF to XHF and all the frequencies in between during my 17+ years in the Air Force and most of the time our cables were coiled both during use and in storage. Never had an issue.

[@TomRolfson]

But that was military cable... it was "special". It cost 5x too much. ;) TY for your Service.

[@Wingrider07]

I was at the motorcycle shop and one of the techs was having trouble with a CB installation. Being a Happy Ham, I offered my assistance. I noticed that his antenna was about 10 inches long. 10 inches may be good for some things, but not CB antennas. He said that he had read that he should “trim” the antenna until he had minimum SWR on channel 20. He kept trimming, but the SWR indicator needle stayed pegged at max. Note: He did not have a cool digital FARSOMETER. Being a “Radio Expert”, I suspected a feed line problem. We removed the seat. He had not only coiled the coax, he had tie wrapped it into a dog bone. The ends of the dog bone were as tightly bent as he could make them. We got another antenna kit an coiled the coax into a 6” diameter coil. A couple snips on the antenna and it was at an SWR of 1:1 on channel 20. As you have said, it is fine to coil coax, as long as the radius is not too small. A radius of 10 x coax diameter is what we use in aircraft installation. A coil of coax will act as an RF choke to signals on the shield, not the signals on the center conductor. As hams we will often have a few turns coil just below the antenna connector. This prevents RF energy coming into your radio shack via the shield. Finally, if coiling the coax damaged it, it would be bad when you bought it off the spool at the store. 73, Happy Ham

[@timbookedtwo2375]

Good test. I am always reconfiguring my antennas and taking them portable. I have pre-cut coax cable lengths. I always make a couple of coils at the base of the antennas as an RF choke. Sometimes the coax is too long between antennas and radio. I just coil up the excess coax. I usually use resonant antennas. Sometimes I have an auto tuner mounted at the feed point of the antenna. I have never had an SWR problem based on coax that was "too long" or coiled up. So much for "the experts." It is not the SWR that could be a problem but attenuation, ie loss of signal strength between radio and antenna. The attenuation is more critical for UHF and VHF frequencies depending on type of coax used and its length. You can find attenuation charts on the internet, or they are included in coax manufacturers' specs. Coiling a coax cable does not appear to affect attenuation in any signifcant and critical, at least in real world situtions like you describe.

Randy, you forgot to add that “if you try this at home, your fars may vary” 😂🤣😂.

[@erikas6874]

In fact it's common among hams to coil up the coax to limit stray RF on the outside of the braid. Or "hot mike" as some older hams would call it. There is no danger involved coiling up coaxial cable, except for mechanical reasons as "minimum bending radius". In fact a big roll of e.g. RG58 with infinite length will be a perfect 50 ohm load. But of course the longer the coax cable between the radio and antenna is, the greater is the loss of RF energy. Best 73 from Ham Anonymous.

[@toml.8210]

I appreciate this.. Since I coil my extra CB antenna coax under the seat, I will sleep better knowing the radio doesn't give a F! OTOH... there are a few (ham radio) antenna experts on here on YT that could give you a one-word answer... with a 20-minute explanation! 😁😆

[@ronwolenski-n8wcr]

You should never ever roll up your coax cable. Having the electrons go around in a circle slows them down. That is why top fuel dragsters are much faster than NASCAR cars. Top fuel dragsters go in a straight line, whereas NASCAR go around in circles, slowing them down. Not only does it slow them down, but the electrons going in circles might get them dizzy and disorientated and they may lose their way. So always run your coax in a straight line, even if it means you have to put your antenna in your neighbors yard.

I'm not sure about this, Randy. For me, this subject hits home, emotionally. See, back in the mid-80s I used to pal around with these two guys; Ray and Peter. Both guys were really smart, both had multiple PhDs in various fields of science. One day, my friend Ray decided that he was going to coil up some RG58 and attach it to a ground plane antenna WITH NO GROUND PLANE WHATSOEVER. I think both of them had been drinking heavily that day because they had just lost their grant at the college they were were working at. The dean at the college, dean Yeager firmly believed that if you coiled up coaxial cable and transmitted a radio signal through that coil to an antenna, a portal to another dimension would be opened up. Well, anyway, Pete thought that was total bunk and so did Ray, which is most likely why they lost their grants and their jobs. The next thing you know, everyone is drunk, unemployed, depressed and throwing caution to the wind by coiling coaxial cable, attaching it to antennas and transmitting through it. Sure enough, a portal to another dimension opened up and a demon named Goser came through it and tried to destroy the world as we know it. Ray and Pete knew that the wouldn't be able to battle Goser by themselves, so they enlisted the help of the smartest man they know; a colleague by the name of Egon. Egon had a radical idea about how to defeat Goser. He theorized that if they all crossed their antennas and directed their radio signals in unison towards Goser, the SWR would flow both backwards and forwards at the same time, thus closing the interdimensional portal, sending Goser back to her dimension of origin and saving the world as we know it (starting with lower Manhattan). The plan wasn't without risks, however. Egon cautioned them that if their timing was off in any way, their radios would melt down in their hands and everyone would be killed at the speed of light. After Egon was through speaking, Peter jumped up and exclaimed "I LOVE THIS PLAN!! I'M HAPPY TO BE A PART OF IT!!! LET'S DO IT!!!" He then picked up his Boefang UV5R (knowing full well that it's illegal to transmit on GMRS frequencies with a UV5R) pointed it at Goser and grunted "Let's show this pre-historic bitch how we do things downtown." Ray and Egon and I joined in, crossing our antennas and directing the crossed radio streams right at our nemesis. Luckily, the plan worked perfectly. There was a tremendous explosion and we were all thrown back about 20 feet and severely burned. Goser vanished and the world was safe from the trouble we caused. Other than that, the only other consequences for the recklessness of coiling coaxial cable and then transmitting radio signals through it, was the fact that the FCC jailed all of us for 8 years for transmitting on GMRS frequencies through a Boefang UV5R. I have to tell you, every day of those 8 years in Leavenworth all I could think about was how stupid we were to violate the FCC rules about the Baofeng UV5R, how incredibly stupid we were for coiling our coaxial cables and how lucky we all were that the outcome wasn't any worse.

[@jvanb231]

huh.. sometimes they tell us to coil it on purpose to make an rf choke to keep rf off the sheid.

[@craigdavidson2977]

True, but that only affects RF electricities on the OUTSIDE of the shield where none is supposed to be. RF signals on the inside of the coax shield is mostly uneffected. Coiling coax does help a little but you are hiding a problem with either the cable or the antenna because there is not supposed to be any electric currents traveling down the outside of the shield in the first place. The more 'non resonant' your antenna is - the higher swr will be on the inside of the coax and that means the energy tries to travel down the outside of the shield instead.

[@bill-2018]

Many radio books do suggest doing that because a balanced aerial such as a dipole when fed with unbalanced coax can induce r.f. on the outer of coax. G4GHB

[@wheel1775]

Does the thicker cable introduce more resistance? I’m new to the GMRS world and am curious if there is a an ideal cable for each type of radio, much like certain antennas are tuned to operate on specific bands or frequencies.

[@TheNotaRubicon]

Short answer: No.. When shopping for cable, you want "low loss", or the lowest "loss" (loss of signal) you can get.. However bear in mind that for the 10-15 feet required in most vehicle installations, the difference between 'high loss' and a very good 'low loss' cable is negligible. Remember: you're not trying to bounce a signal off the moon, you're just trying to talk to your friends a short distance away. If you're installing an antenna on the roof of your house, and running 50 or 100 feet or more, then the loss really makes a big difference and good quality low-loss cable is much more important.
