Hi,

Is it possible use only 1 Antenna each side (clearly in a p-t-p link) but dual polaritation instead to use 2 antenna each side?

right or wrong? Advantage?

thx and happy easter everyone!

RouterOS doesn't really care what antenna's you use, but you need 2 radios in one unit at each end to do Nstreme2.

Having a single dual-polarity antenna gives you the advantage for easy of install and alignment, but limits you in that you have absolutely no physical seperation.

I have done this in many cases to save on tower space, and it works great. However, I don't use nstreme2, I run 2 physically different routerboards, with each radio RF shielded from eachother then I use routing to simulate a full duplex link. This gives me the advantage that if one radio/routerboard fails the link stays up. Either way use as much frequency seperation possible.

Cheers

yes, but in your case you have 4 routerboard and 4 antennas to do a full-duplex instead of nstreme2... more expensive and expecially more space troubles...

I agree that is better your version, but most probably my solution is the most used

more or less the score is the same....

don't you?

I just recently set up a link with Nstreme2 using a dual polarity ant w/enclosure. It is just a short link; around 1/4 mile. But so far is working very well. It has only been up for about 1 week. But so far has been stable with good throughput. I am using R52's with RB333 boards.
