Yaesu: Connector

[Delivers1234]

What is this? I thought it was a male sma to male uhf. I'm trying to connect ft2dr to base antenna.

Looks like a female SMA to a female SO-239 (AKA UHF)

The other trick you have to watch out for is the "RP" connectors, which are the reverse polarity connectors used on a lot of Wi-Fi gear. The outer shield will be one gender and the center pin will be the opposite. Really annoying if you get one by accident.

I think what you need is a male SMA to UHF. You could buy an adapter to make that cable work, but it's probably easier to just order the right one.

I thought male meant the connecter goes into...

Yeah....

The male connectors are on the radio chassis on many of the brands, Motorola, Kenwood, Yaesu, etc. Look for the little pin sticking up.

the gender of the connector is determined by the center pin, usually. or as my tag line says:

It goes by the pin and it's hole not the threads.

Here's a photo example, Delivers-- a Female SMA

Gene, here's a URL site that has pictures of the various types of RF connectors. If I can find the other site that shows more, I'll message you.

Coaxial RF Connector Identification Chart

Hope this helps you some.

Here's the PDF file for those connectors that you can print out for quick viewing:

This a adapter cable to connect HT radios like Baofeng and some older Wouxuns to coaxial cable. These radios use a "Reverse SMA connector" which is the opposite of a normal SMA like you'll find on Yaesu.

No, Baofengs, Wouxuns, Motorola and other simply have a male SMA on the radio chassis and the mating antenna needs to have a female SMA. A female SMA has external threads as your adapter cable and a socket or hole for the center. The male will have internal threads and a protruding pin. As mentioned by others, a standard connector sex is determined by the center pin with a protruding pin being a make and a socket or hole being a female. The picture posted by Coyote-Frostbite is a standard female SMA.

A "reverse" SMA is a much later invention where the male will have external threads like your adapter cable and a protruding pin down inside. The corresponding reverse female SMA will have internal threads and a hole or socket in the center.

You all are confusing me. I ended up ordering this but my coax cable is very stiff/sturdy. I'm afraid if I move the ht I'll start losing the sma connection from the ft-2dr. I didn't find the dongle kind that had about 5 inches of thin wire in between. I'll look for that one. It's for a temp setup until I get a base radio.

The FT-2DR has a standard female SMA connector on the radio and you would need a standard SMA male connector on a jumper cable to fit. Your original jumper cable appears to have a standard SMA female and you found it doesn't work.

Your right about the adapter on your larger cable in the picture putting stress on the radio connector and a jumper with smaller coax is a better way to go.

The first Chinese radios were said to have a "reverse SMA" connector because it was just the opposite of the SMA connector on Yaes, iCom and Kenwood radios. It was recessed into the body of the radio instead of protruding from the top. The adapter the OP shows in his original is for those radios.

What you need is exactly the same thing you showed in your original photograph but with the following SMA connector on it. I've used this one on three different Yaesu HTs and, with a BNC adapter, a couple of scanners and an Alinco 22 HT.

This adapter can be found at HRO: COMET-NCG HS-05 Cables Coaxial, HS05
