  • As you say it is very dependent. I’m currently getting a 1km'ish in town (low rise houses) out of the Modtronics modules. I’ve done a small amount of testing in open terrain and I’ve got many km’s out of them. The RFM22B modules have excellent range.

  • I’ve got this item, which is good, but if you want something with better performance I’d probably recommend the Modtronics RFM22B Breakout

    I’ve used both the sparkfun and Modtronics version. I have them setup on breadboards and have been controlling them with Arduino’s (there’s a really good Arduino RFM22B library out there). They both work great, except I get about 150m further range out of the Modtronics version and that is just using the basic stub antenna they sell. Attach a Yagi antenna or similar and you’d get heaps further again.

    Good radios the RFM22Bs!

No public wish lists :(
