Hey Adam, I am curious as to why you are saying the used Dragonwave deal didn't pan out???
I still have the system here and Mario can have it any time he wants. 200 Mb full duplex with his choice of used 4' or new 2' antennas. I even offered to deliver it to your office over 100 miles away from me at no charge. According to Mario the "deal breaker" was I was not going to let him take the link, install it, and "try it" for a week or two and then let him make his decision. He says he was worried about "interference". Well I have more than forty 23 Ghz. links in midtown Manhattan without issue so I doubt you guys are going to have any problems getting a clean channel in rural Kingston NY. $10K for a Dragonwave Airpair that is a little over a year old with a choice of either 4' or 2' antennas is a steal. This link sells for $20K+. The real issue was not interference. It was money. It's really a shame Mario couldn't tell me that instead of using interference as an excuse. If anyone else wants this link I will let it go to them for $9K until February 10th.
