I have a spare RFX-250i with a missing antenna. I have tested that it works with one from another RFX-250i, so now would like to get a spare antenna for it.

Can anyone tell me what type of antenna is required please?

For example, does the following description sound suitable:
433MHz SMA male right angle GSM GPRS Antenna
Frequency Range: 434MHz±5MHz
Bandwidth: 7
VSWR: ≤1.8
Gain: 2.5 dBi
Max Input power: 50W
Input Impedance: 50Ω
Polarization Type: Vertical
Antenna Type: omni-directional

Thank you

Steve

Why not try URC? I have ordered a couple of batteries. They were very helpful!

Thanks Ted.

I'm in the UK so I'm hoping to get something locally, but I'll call them if I get stuck.

In case anyone else has the same problem, the antenna described above worked fine - cost $2 from ebay.

The part # is RFX-250i .

It's not a mainstream part, so look around but don't assume a warranty if you buy it online.
