I seem to remember that Mikrotik had a point to point data device that operated I think it was in the LIPD band at 32cm or perhaps 70cm. I cant really remember. It was low speed and I seemed to remember it only has a small amount of access to the band as it did not line up correctly with Australian band plan. I cant seem to find it any more. Does anyone know what im talking about ? Matt /* Matt Perkins Direct 1300 137 379 Spectrum Networks Ptd. Ltd.

Hi Matt! I suspect that you are thinking of RBMetal9? It's like a MetalG52, but operates in 900MHz LIPD class band. https://shop.duxtel.com.au/products/metalg Production of Metal9 was discontinued about a year ago due to what they called 'low demand', which for them means something probably less than 100 units/quarter. To be honest, 900MHz equipment of that class is no end of trouble due to proximity to voda mobile phone band. Besides that issue, there is only about 14MHz of band available for use as LIPD, and so best throughput using 10MHz channel, single polarity was only in the order of 10Mbps of real tcp throughput, and only where no other competing transmissions. There may be other vendor products still available in that band (UBNT had/has one as well as others) but TBH, I'd encourage anyone to avoid it for anything other than ad-hoc telemetry applications :-} Cheers! Mike.

That was what i was thinking about The Metal9 Yes i knew it was a bit on the slow side but it's for regional voice between a couple of sites with some bush in the way. I was thinking of a couple of yagi but I might just go back and look other stuff i can find in lower bands. as I doubt 27db wold have cut it anyway.

It was good for that kind of low throughput and nlos application - that's really the /only/ thing it was good for (perfect for through trees and around hills ;) if a few MB was all required.
