As a noob to Ham, an Elmer had suggested an adapter system like these for multiple access points for HTs that deploy SMA thread connectors to various upgrade or mobile whips, fixed, j pole, antenna, etc.The 58 co ax I use for roof top J pole, has a BNC F and a few of some very nice whips did too. Using a pig tail just seemed too flimsy or going 239 to SMA on a regular basis seems like the SMA would wear out rather quickly or fail at some point. BNC is a great solution. I just had a heck of a time fumbling through the often opposite described male or female translations for what I needed. THIS is the one!! Finally! If this issue with fit, and length, threading etc is a concern, these FIT. Well made, no issues. Definitely recommend.I plan to seat these in all my HTs that use SMA connects and buy or adapt the various antenna that match up. SO much easier and I haven't noticed any loss but again, I'm not a seasoned radio Ham and have a lot to learn in this very cool old school hobby/league of good guys. I have had a lot of prior experience with old RC rotary CP build it yourself birds, so some of the subjects are meshing up nicely. This is truly a DIY type club hobby and wow was it difficult at first. Still is. All the different networks that are or aren't compatible with this one or that one, digital and analog switching, repeaters, programming cables with chips, whether it's OS or PC only compatible, CHIRP or not, using your own array of .csv files, good grief I have come close to giving up many times. At present, I am waiting until the next test date to take both at the same time and have just been a listener for the past 6 months. That is the number one reason I decided to stick with the Ham endeavor. It speaks volumes that a community of helpful, skilled, wise folk with many great QSOs exist, and actually speak respectfully with each other. It's much more interesting to listen to various local and national groups on the uhf bands than the junk shows on the all new and even more idiotic 'idiot box'. Yeah I guess I'm an old school type at heart in many aspects of life. Military and LE vets, often aviation and engineering backgrounds definitely piqued my interest in becoming a licensed Ham as they are most of whom I've always circled in solid brotherhood. It's a neat hobby, and a challenging one technically wise. As a former RC mentor said when we were flying 2-3-6 axis collective pitch money pit flying lawn mowers, "if it was easy, it'd get boring very quickly". When fly by launch and return button quads overtook custom build high performance or scale flyers, meant the shelved array of some very cool very precision instruments and faded kinship with some good friends, at the forefront of old school innovation. I don't see Ham going 'plug and play' any time soon. So onward and a new journey begins. 73s

Perfect adapters for my WiFi in my camper, perfect price

These are exactly what I needed to adapt my cellular modem with nonstandard terminal to a standard cellular antenna. They fit and function well.

There is not much to say about these as they are such a simple product.I needed these as I ordered a pair of ev100 goggles and I could have sworn it said that it was an sma connector so I bought sma antennas then when I got it they were rp-sma so hence the need for the adapters.I received them quicklyThey came screwed together in a bag in a box so nothing smacking against each other or anything so that was good.They workThey don't feel cheapThey are pretty much as small as they could get them, maybe could have removed 3mm in the middle but that is just nit picking and they may need that for some weird sma connector that may be out there, who knows.I already have them mounted and they are working great.

Good quality. Connected to my baofeng and performed well. No complaints.

THANK YOU 100%

Returned item because there is no middle pin. The middle wire is essential, while casing is all ground. Without that pin (unless it was a defective part), it appeared manufactured with no continuity possible. Also it says it is Coaxial (e.g. standard TV cable) to Wifi antenna (a smaller version of the coax cable connector), but this item wouldn't do anything useful -- it was small on both ends, and couldn't even be used to extend two wifi antenna cables. You would need female to female WITH A MIDDLE PIN to do that.

works as expected, tightening these things is a bit wonky.
