Most indestructible so-239 antenna stud mount

Out of all the studs that are mass-produced this is the strongest one I have found.
I'm not normally too fond of Chinese products, but they have outdone themselves with this item.
Unfortunately A1 Telecom has discontinued this item and nobody in this country seems to sell it anymore but it is still available through Alibaba.


the plastic insert is made out of a harder plastic and will not Crush. the bolt will snap before the plastic crushes.

 

Feel free to tell your local radio shop you would like this item because it is more durable than anything commercially available at the price.

I think the reason A1 telekom be discontinued this stud is because the hole in the head of the bolt is drilled a little large and a little deep preventing a good electrical connection but it is something that is easily fixed with copper or stainless Brillo pad rolled up into a little ball and tucked into the hole with a toothpick to fill the void and make a good connection.

 

Here is the manufacturer.
This is probably the same company that makes all the cheap Barjan junk. At least they make one thing that's decent.

Have you checked out the Wilson, its fatter than most, made of SS, and uses a hex key to connect the two halves through the top. I bought it thinking it was a normal threaded stud, but couldn't get the darn thing apart, I seen the hex head and threw it under the seat for another day.

 

Over tighten the wWilson stud will crush plastic insert

 

Are you talking about the insulating washer, or now as I'm writing this, I think about the plastic on the inside of the stud...ahhh haa moment! I've never given that any thought. I just replace the studs every time things go cruddy which happens quite often on my passenger side, tree branches I guess... its all making sense now.

 

The stud is only as strong as its weakest part which most of the time is underneath the head of the bolt inside the stud when you hit a tree branch it shorts out. A good stud should be stronger than the antenna itself so you should never have to replace it even if you hit a tree branch.

 

Thanks for the face in palm moment.

 

The characteristic impedance of that type of stud is way off base from where it should be,
Probably closer to 20 ohms which is awful but most people don't want to spend fifty bucks on a Breedlove mount with a 50 ohm characteristic impedance and then spend a couple hundred bucks more having a custom bracket made specifically for the Breedlove mount so this is a cheap alternative which is very strong.
The only problem with using one of these types of studs is that you will never get an accurate SWR reading with an SWR meter while using one of these studs. That's why it's so critical to use and antenna analyzer at the very least
