I'm prewiring, new construction, 4000 sq' home with an RTI system.

I want to deploy 2 RTI 433hz antenna modules, 1 on the south side of the home, the other on the north side of the home.

So I will need to prewire for both those antenna modules.

In the past I've used Cat 5/6 with URC antenna extensions. Not sure what is proper with RTI. I'd hope you could use Cat 5/6?

Each run will be appx 50-60'

Anyone have an experience extending these RTI modules?

The RM-433 RF receiver has a standard IR output with power and ground. Very similar to how URC's RFX-250 RF antennas wire. So cat5/6 shouldn't be a problem, especially over such short distances.

So it’s a 1/8” 3 pin Jack? Tip, ring, sleeve? Power +, power - and signal?

Any issues combining 2 different RF receivers into one processor?

Looks like it has BNC plug- I guess you can use whatever you have for cable and use the lugs you might have used for analog cameras.

??? WTF ???
Dude, look up RTI RM-433. Look at the picture for a minute and then come back and try again :)

It uses a 4 position phoenix connector. Which only 3 are actually used (Power, Ground, signal). On your Cat cable, I would double up the conductors on power & ground (suggest the 2 orange for +12VDC, and the 2 brown for Ground) and then 1 pair for the signal (suggest Blue to Ground and Blue/white to Signal).

Install manual mentions combining 2 antennas, so no issues there. I just don't know the max antennas you can run off of 1 processor.

I did, before I posted but I vapor locked when I saw that he used Category cable, Dude.

I wrote that whole post without any coffee.......

If someone only had coax ran to a location and needed the antenna there, it might work. Although it wasn't designed to be used that way and BNC connectors would add more expense.

But BNC connections could indicate the product is using a 50Ω system (specs don't say). So that could pose a problem with performance, using RG cable at 75Ω if so.

Not that it matters for this particular topic but you are aware that 75-ohm connectors exist, right?

Yes. But having 75Ω BNC connectors on the 75Ω RG6 cable isn't the issue. The issue is the system RTI uses is probably 50Ω, not 75Ω for their antenna.
For just receiving signals, it probably won't make enough of a difference to even notice.
But doing 4G/5G repeaters, VHF/UHF radio transmitters, etc., it becomes critical that the proper cabling & connectors be used. Otherwise an extremely high SWR can burn out transmitters and cause noticeable reception issues.

I have run Cat 6 cable to 2 different areas of the house and hope to terminate the conductors on the 3 phoenix connector...and combine those 2 feeds onto the phoenix connector back at the processor.

That will work. The receivers are dumb, so the processor does the work.

Don't try to extend the RF antenna with coax more than a few feet. The losses will not be worth it with the stock antenna.
Also, many 70cm ham radio antennas can be used if you have a lot of room and need to
put the antenna in the attic .

the rf antenn is 50 ohm from what i remember...but the module can easiy be extended with cat5/6/7 from head end to remot location.

i had no issue running 2 rm433 extenders in the past.. i see no reason for an issue now. its been a very long time but i think they had to be addressed so you dont get neighbors rti systems controlling.


extend the rm433 not the antenna f that makes sense.

Thanks Ed. I plan to remote install both the entire rm-433 modules, not the antennas. Each run will average 50-60’ of Cat6
