Whistling 2-way Radio Antenna’s

I installed 2 fender mount antennas. 1 is for my cell booster and the other is for my 2 way radio. They are both normal NMO mounts and on opposite sides of the truck on the rearmost top fender bolt position. Same place almost everyone puts them on every truck. 
 

Now I’ve ran dozens of different make and year of trucks with 1 to 3 of these style mounts on them and never an issue before but on this truck as soon as you get up to highway speeds and especially into a headwind they whistle like crazy. And loud!!!

 

Anyone else run into this with this bodystyle or have any suggestions on how to fix the problem? I don’t want to go back to a magnetic mount. Scratched too many roofs and had too many wiped out by parkades, snow, car washes, etc.

Did you install the NCG CV3ANTNCG?  I have one mounted on my Sierra on the driver's side using an NMO Larsen 150/450/800.  It's only about a foot tall, but I do not experience any wind noise from it.

 

Only thing extra I did was to install some heat shrink tubing on the bracket in the area where it sits between the fender and the hood to eliminate any metal to metal rubbing.973042926_NCGMOUNT.thumb.jpeg.80d65044df2c75f8cdfdc6bb98d9a180.jpeg

Installed a what now???

 

My setup is a different antenna but mounted and routed pretty much the same.  I’ll get some pics today.

Couple pics of my setup. It’s definitely the antennas and not the mounts. I ran  for a bit with the antennas unscrewed and almost nothing for noise from them.

Sorry, the  NCG CV3ANTNCG is the antenna mount made by NCG (comet).  I didn't make that clear.

 

FYI, I had my truck up to about 80 the other day on the interstate and I noticed a slight whistling noise, but it was not too bad.

 

Since my setup is on the driver's side, I ran my coax through the grommet the hood release runs through.  Figured if I nicked the cable, it was mechanical and not electrical.

 

Anyway you could switch to a lower profile antenna without sacrificing performance?  It may decrease the noise for you.

 

Good luck,

I could put a longer or shorter 2 way antenna and try it. The cell phone one I’m thinking of just putting a stubby Omni directional one in to eliminate the whistle altogether.

So I cut the antenna part off my booster antenna and the whistling from that antenna went away so I think I’m going to order a Browning stubby to replace it. 
 

Now I just need to figure out my 2-way antenna.

      I never understood the hate for the column shifter. The console shifter just gets in the way, takes up prime cargo space and in my wife's Jeep, the dog constantly bumps the console shifter into neutral!    Best choice ever to just make it a column shifter across the lineup and be done with it.    (Bonus: Makes swapping from a 5 seater to a six seater far easier)

      Wow I'm in a pickle. (Broke down truck) and a story.

      I had an 88 K1500 with a 5.7 that had those symptoms, I know totally different, it ended up being the ECM. Once you get the fuel system fixed if it still runs lousy you may want to investigate that. it didn't set any codes, stalled ,ran rough at times etc

      Trading 7.3 (Godzilla) for G.M.C gas

      Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-

      Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.
