Rhode & Schwarz 225-400 MHz Multicoupler

[zguy1243]

Just bought a Rhode & Schwarz UHF 225-400 MHz multicoupler. Can anyone ID the connectors on the rear? I need to have patch cables made and these are different from anything I have ever had. The unit is being shipped to me and when it comes in I could take better photos but I was hoping someone could ID them in these pictures the seller provided me.

Thanks,

7-16 DIN, those are the female on the multicoupler. You'll want Male for your jumpers.

Be aware, they are not cheap. Depending on the coaxial cable you'll be using, figure on $50 a connector, maybe less if you shop around. Adapters are available, but they won't save you a whole lot.

The only adapters i have seen before are 7-16 DIN to N female in the form of
a short hardline pigtail which i purchased at a hamfest but i have not had the
need for anything other than the great find i made at that hamfest.

thanks guys. I thought they looked like DIN connectors but I didn't think R&S used them. I started using 7/16 DIN on all my UHF antennas and hard line last year. I really like them, very solid connectors....

I've got a set of direct 7-16 DIN to N connectors for testing, not jumpers.

I was going to have some made I guess or make them myself. This multicoupler will run my receivers that are running 225-400 only. Some of the radios use BNC and others N. I am wondering if they make the 7/16 DIN connector for smaller cable that I can make custom jumper cable assemblies from. I have had RFparts company make my jumpers in the past,. They are really nice , swept tested and all but tend to be really expensive...

I know you can get them for LMR-400, RG-213, RG-8, LMR-240, and RG-58. There are likely other options, and you can certainly get them for stuff bigger than the LMR-400. If you are running short jumpers to your equipment, the RG-58 or LMR-240 might be your best bet for flexibility.

If you shop around, you -may- be able to find adapters to close to the same price as your new jumper cables. Might be a bit cheaper to go that route.

Why not just replace the DIN's with female N or BNC? Save yourself the trouble.

Good idea, however since I don't see a retainer nut holding those in place, I suspect they are part of a larger assembly. The top would need to be removed to know for sure.

+1 and probably cheaper too. :
