Wireless MPG Frequency

[kman1967]

I am looking to use a different antenna on the USB transceiver for my Wireless MPG. Can someone tell me the operating frequency for the unit. 433Mhz, 900Mhz, 2.4Ghz...?

Hello,

It does not say anywhere on them but they run in the 433 MHz ISM bands.

I found that out from taking one apart and measuring the antenna length, observing the communications with a spectrum analyzer, and from measuring the response of the antenna for the USB transceiver a year or two ago. I think I also found the part number for the transceiver inside the pendant but I cannot remember it right now.

Just to update for others. The frequency is 433Mhz at least the antenna I installed works with it. The antenna is specifically for 433 but may cover a wider band. Either way it works and has a very strong signal.

Thanks centroid467
