Re: [Mikrotik] 5.8GHz Grids
Turning them down will help some. The issue is on the tx. Using untuned antennas (like out of band tx line) you get power reflected back at the radio doing the transmitting. Lower power means less reflected but it will still be there. How long and how much it will affect the radio I don't know. May last a good while. CM9 is cheap, you could try it and see what happens.

I'd think that lower power will be fine. I can get you a set of radios, power supply, RB411, outdoor antenna enclosure for $139/end.

Re: [Mikrotik] 5.8GHz Grids
Thanks for all the replies. I think we're probably going to try it out. Like I said, we're trying to keep costs down and we have plenty of 5.8 grids and cm9's sitting around doing nothing. It's going to cost us enough for the new t1, plus the man-hours switching all the clients over to the new tower. --- Aaron, MCP, Network+, A+ Network Administrator suppo...@greatlakes.net Great Lakes Internet, Inc 112 N.
