SS-3H CB Antenna Spring, Stainless Steel Heavy Duty CB Radio Antenna Mount Spring, Spring to Fit Mobile/in-Vehicle CB Radio Antenna Mount Up to 60" Long and 3/8" X 24 Thread (Black)

Made from good metal; very flexable holds my CB antenna firmly; worth your money; easy to install

So far so good. Seems solid yet allows 3' antenna to flex without being to much flex.

I Consider My CB System "A Labor of Love" as I've been "Developing It" for MANY Months. Multiple CBs, Different Antennas, Cables, Attachments, Enhancements, etc... Eventually, I now have Dual 9' Whip Antennas with "Coil Overs" (Stryker SR-2K - which I had to "Modify" to Install) - https://www.amazon.com/gp/product/B00S74X11G/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and Subsequently - my Antennas are "Relatively Heavy", but... Extremely Effective for my Wants. I've Attempted Multiple Springs - from Multiple Sellers/Manufacturers - at Different "Stiffness" Levels. But I was always Dissatisfied with the Results. So, in my Quest for a Spring I could be Pleased With - I ran across this one - and it is Absolutely Perfect "for my Needs" as it is Extremely "Stout and Stiff", but... Please Note that I Specified "for my Needs". If you're Worried/Afraid about your Antenna Breaking and/or Being Damaged by Trees, Low Hangs, High Winds, etc... This is "Not" the Spring for you and I would Highly Recommend you get Springs that are Not as "Stiff" as these are not very "Forgiving" (to say the Least). But if you want a Spring that is Stout and Stiff - then this is the One I'd Highly Recommend.

It's a spring, not much to say in a review. It's working as it should so far. I don't remember if this was a "medium" or "heavy" spring, regardless, I haven't slapped my antenna against the cab yet. This is on an F-250 work truck, nothing crazy offroad but enough. Think cattle ranch, oil field work. Not Moab, Arkansas mud tracks. Serves my purpose though

Works amazing with a 102 whip. Perfect swr after grounding my mount to the frame instead of a plastic bumper. This spring is a very good balance between springy and stiff. Keeps my antenna from folding but when it hits something it allows it to move out the way. High speeds keeps the antenna attached, does fold a little but nothing C r a z y.

Exactly what I needed for my offroad application and using my CB radio antennas. Signal is strong and after I properly tuned, I get great range still. Best bang for your buck with still getting a quality product. I ran this on my 6ft antenna and while it is just a little flexy, it has been working great for weeks now on my daily driver/weekend warrior. A+ Product.

Pretty good. No issues

Nothing good comes from China, this spring included. It falls apart with normal use. I installed it with my CB antenna on my truck. While driving on the highway for less than 100 miles it started to come apart. I had to buy some Loctite and reinsert the end pieces just to make it back home. I almost lost the antenna on the road while driving. Don't buy this piece of crap!
