RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

How many times have you dug through a drawer of coaxial connector adapters and found what seemed like every possible combination of TNCs, Ns, SMAs, TNCs, UHFs, SMBs, and <fill in the blank>s except the one you really need? Sometimes the reason is simply because all on hand are being used for something else and cannot be 'borrowed' for your use. Other times it is because the need never existed before. Usually, a quick search on the Internet will turn up exactly want you want, but for decent a quality adapter you will pay a stiff price - especially if it is a rare combination of connector types. The truth is, not often is a combination like QMA-Male-Right-Angle-to-TNC-Female-Bulkhead adapter or a BNC-Female-to-D-SUB-Plug adapter required. That is why other than paying a manufacturer to build a custom adapter for you at a breathtakingly high price, you will likely end up stringing together two or more between-series adapter to get from point A to point B. Needing to do so for a piece of production equipment gets nasty fast from aspects of reliability, cost, real estate, and electrical performance.
Thankfully, a company named CoaxSol (shorthand for Coaxial Solutions) recently came out with a line of both between-series and in-series adapters that uses a proprietary interface dubbed "Open Cable Port Connector Concept," which is a modular system for providing a high RF quality common interface junction between any connector types. Doing so makes constructing a BNC-Female-4-Hole-Panel-Mount-to-QMA-Male-Right-Angle adapter as easy to do as a typical BNC-Male-to-SMA-Female adapter, and for about the same price! The former costs $55 while the latter costs $39.
But wait, the goodies don't stop there. CoaxSol also offers what they call '3D RF Adapters' that offer just about any relative orientation of connector ends. Tee RF Adapters, Cross RF Adapters, Quick Disconnect, Radius Right Angle, Open Cable Port, and other innovative designs are also available. CoaxSol says it won't be long until they offer half a million different combinations!
This is from CoaxSol's "About Us" page:
Coaxsol (short for Coaxial Solutions) debuts its entrance into the RF Microwave world as a Custom On-Demand Manufacturer of an unprecedented 177,000+ RF Microwave coaxial Non-Existent Adapters & Connectors used by the military, the aerospace and commercial markets such as wireless communications, medical, test & measurement.
Due to the high cost and time delay in the manufacturing of new adapters & connectors, RF Microwave Engineers and Technicians are forced to build their designs and prototypes only around the existing RF components available to them.
Coaxsol's engineers have developed the "OPEN CABLE PORT CONNECTOR CONCEPT", a patent pending technology that made it possible to create, deliver On-Demand and increase the number of RF Microwave Coaxial Adapters available in the market today from approximately 3,500 to over 177,000. The numbers are expected to surpass 500,000 within a year. Over 97% of the CoaxSol branded adapter and connector products have never previously existed in the RF marketplace.
With an engineering team whose expertise spans a combined history of over 100 years and after 2 years in development, Coaxsol brings new custom coaxial solutions to the RF Microwave Industry that never existed; thus putting an end to costly long lead time solutions by making non-existent adapters and connectors readily available upon demand.
