Hi, its very unlikely that you will permanetly damage the input with -40dBm, however with that level of input the preamp is probably in compression, therefore producing intermod and not performing as well as it could.

The 60GHz hear is a bit more expensive, then again it will do Gig throughput. Unfortunately the cheapest 60GHz kit is around $350 for a pair of mikrotiks wireless wire's but 250m is pushing it, hence the cubes, around $400 for a pair is the go.

Yeah it did also cross my mind to run a 300m length of fibre to connect the 2 buildings but I'm fairly sure that will be more than $400 :-)

You can get a 250m pre-terminated cable made by FS.com for under $200.. Just gotta run it down a roll of Alkathene or something?

Thanks @raytaylor for the reply.

 

at about $500NZ

 

Thats quite cheap or a bargain price for the throughput and higher reliability they give.  

Remember a proper link is $8-15k for a proper licensed link. 

I've got a spare, unused (powered up and updated to latest version then reset) (MikroTik RBWAPG-60ADKIT Wireless Wire, Gigabit Wireless Bridge Kit if anyone is interested. Happy with $250+shipping.

My reading tells me I'd need the slightly bigger "cube" versions.. But would have been keen!

yes, Mikrotik blurb says 200m or more - but ive not used them over a distance great than 100m. others here say 100m and i assume they've tried over greater distances and havent had much sucess. The cube looks cool though and the 5ghz backup is a bonus - my supplier however is out of stock of the cubes.
