I new to purchase pigtails that are 20 inches, UFL to N female, that will be used to connect R52H cards to external antennas. These will be connected to an X86 system housed in a case that I have built. does anyone know where I can find this lenght pigtail or point me to where I can get them custom built. Thanks.
Here in South Africa, it’s possible to buy the RG-316 double braided cable and get these made up by a company called RF Design without any problems. I recently needed 12 that were 50cm long for a new high site. They came in quite expensive though. About US$13 each.
Honestly, that’s not that bad of a price for a custom built ufl cable. I wish I had someone I could recommend that would make the ufl cable for you, but I currently do not.
The smallest coax that we work with (for custom cables) is LMR195 and most often we make LMR400 cables for customers. The smallest connector that we have for LMR195 is SMA or RPSMA. MMCX and UFL are much smaller and require much smaller diameter cable.
We purchase pre-made pigtails in bulk for the smaller cable and connectors. We have MMCX pigtails in 6, 10, and 12 inches which usually cover our customer needs. If they want something longer, they usually adapt larger cable to the pigtail.
I think the special tools, strippers, crimp dies, and test equipment are keeping us from working with smaller coax and connectors.
I don’t know of any small distributors in the US that work with the smaller diameter coax and connectors.
To expand on Tom’s statement, most of the cables purchased by customers fall into a very specific pattern. If you need a UFL to NFB connection, in 99% of all cases one of our three standard lengths (5 inch, 8 inch, or 12 inch) will work. It’s actually very rare (though it does happen like in your case) to find a situation that needs a unique length for any kind of pigtail that directly connects to a card. Most custom pigtails are for external connections ([RP]SMA to N, etc).
We (WISP-Router) do go down to the next smaller size (RG174) where we can do an MMCX connector, but UFL is a different beast. Because the demand for custom UFL cables is almost non-existent, we just do not bother with the hassle of trying to work with making a custom UFL cable. The size of that connector makes it extremely difficult to work with and get right without shorting out the cable or making an otherwise bad connection.
If you can use a card that has MMCX connections, you should be able to find someone that can make the cable you need. If you must stick with UFL, you’re task will be much more difficult.
