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

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.

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

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.

[@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.

[@garyclark4930]

Thank you for the video. Coiling up your extra cable not cause high SWR which you just proved. I have built a lot of antennas and have coiled up close to the antenna connection with certain antennas to prevent RF from coming back to the radio on the outer shield. I have never heard coiling up the cable caused high swr or lowered the power output. Keep up the good videos.

[@IRDeezlSmoke]

Hey, I started as a ham a few years ago and got turned off by sad hams. Have found a better group and am back in it again and got my GRMS while I am at it so i can convince my friends to get radios too. Thanks for being no BS and showing me GMRS

CB radio was the top gateway drug to getting people into the ham radio community.. Now it is FRS, people much prefer the quieter FM mode and once they find out that a licensed ham can use an HT and talk to someone on the other side of the world their small FRS bubble looks far smaller.. Well like any hobby you get those that are like that, even the radio clubs can and do become cliques for snobs.. Since most people have real lives outside radio it may be hard to find the kind of people that are amiable..

[@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.

[@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

[@itsapittie]

Watching this prompted me to test it for myself. I used a Nagoya UT-72G antenna on a pie plate and a Baofeng AR-5R radio. I tested with the coax straight and then coiled the coax in a neat coil about 5" in diameter. I tested on GMRS 6 and GMRS 16 and just for the heck of it, I also tested it on MURS 3. I repeated the experiment 3 times and discovered to my surprise that it did seem to make a difference. The difference ranged from 0.02 to 0.1 but it was consistent. The larger difference was on MURS 3. I can only guess that it's because the UT-72G isn't a dual-band antenna and didn't handle VHF as well as UHF. I don't know why my results were different from Randy's, and to quote Paul Harrell (RIP), it's not enough difference to make a difference. Maybe induction? I don't know. But it doesn't matter.

[@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.

Good video, good real-world data. Another data point: you should avoid kinking coaxial cable (or any kind of cable such as ethernet). This can cause impedance issues. Minimum bend radius is 5x cable radius.

[@adcraziness1501]

I'm just getting started in this side of playing with radios. I'm still pretty stupified by Smith charts, though I at least understand the concept. Yes they are simple; I get that. But not if you don't understand the fundamentals yet. It's a lot to try to chew at once. Return loss, VSWR, it's so much to learn. But I already know more than I did when I started. EDIT: Seems to me that a flexible cable has a healthy bend radius. A lot of times this data is provided. As long as you aren't sharply bending or kinking your cables, they should perform within their norms. Now if you compare a sharply bent cable vs a new one "laid out straight" you might find a different reading on sensitive test equipment.

[@SouthEasternCommunications]

Good one randy ... next do the oh but you cant cut your coax it has to be an exact length ...ive watched a dozen or more vids on installs on 4wd and almost all of them say cutting your cable will effect the swr .. i laugh ive installed hundreds and cut cabes to fit never effected the swr ..

For sure, standing waves occur when you have an impedance mismatch (varies from 50 ohms at your alternating current frequency, when your line to load have a reflection from a "discontinuity," kink in the line or other factors that change the distance from the center conductor to the other conductor, moisture/vapor/water/dust/bugs... or other stuff in-between), loose or otherwise nasty connections, extraneous electromagnetic waves penetrating through the shielded connector, or worst of all - EMPs and/or direct hit by a nuclear detonation!

[@Calico5string1962]

The length would be important, and longer would probably be better (although, the cable loss/return-loss in the smaller cable would certainly make the indicated SWR actually better). Also, in order to perform a valid test, a load with a known poor SWR would be needed... i.e., a "badly" matched antenna, or an intentionally un-matched dummy-load (e.g. a 75-ohm resistor of sufficient wattage). This would then present a higher VSWR along the line, and may show a more noticeable change in any "choking effect" and SWR change of a coiled cable (in similar fashion to an "ugly" balun) vs. an uncoiled cable. Otherwise, somewhat interesting but really meaningless. A similar test at higher-power HF would be interesting... 73 from west Texas!

I read that 1 FaRs = 10^5 Smidges witch is equal to 10^11 c-bomb hairs.

Would this effect power at the other end ?

I have about 25' of rg8 coiled up for my cb and have great swr

Honestly never heard of this, but it sorta seems plausible with crappy cables... Looking forward to this video Woah, 1:1.01 SWR! i also get that with my MJF discone/50ft RG58/SO232>SMA

You should use enough coax cable to establish your antenna. As far as coiled. It takes miles at the wattage of a radio to create a electromagnetic field to consume the wattage. Every form of rf shielding leaks the length of said cable is more destructive than coil, ball, serpentine, or straight. At 10000 watts you can get shocked and hurt even cooked a little. But it should not change swr. You tune the antenna not the cable.

[@JohnHill-qo3hb]

If coiling coax cable is bad for it, please explain why EVERY manufacturer supplies it either on a round drum/spool or coiled in a box. Every cable has a minimum radius bend specified by the manufacturer before any detrimental effect. I learned some time ago that handling coax during an install and coiling extension cords is made much easier if the cable is laid out as straight as you can get it in the hot sun. The plastics heat up and become much more malleable.

Not trying to be a sad ham. but real question. do you guys think if you pushed the power to the 50 watt limit it would make any difference?

[@TheNotaRubicon]

SWR is a ratio of reflected power, so no matter how much you push in (to a point), it should not make any [significant] difference as that ratio would stay [mostly] the same.

@@TheNotaRubicon hey, awesome to know! thanks for the awesome videos.

[@sonic2wb]

Great Video! love your content!

[@TDanNix]

Whew! Well I guess I dodged the bullet on that one, I've coiled hundreds of cables over several decades, I'm so glad to know that the rampant confuckelment all around us was not caused by me,... well maybe part of it
