I have to say I did a double take on your speed claims. We use Solectek 
all over the place and have yet to archived those speeds on any of our 
links. Not only that Solectek engineers have told us that at a 108mbps 
radio rate realistically you are only going to see only 35mbps  data 
rate on link that's just a mile apart; further you go the less bandwidth 
you will have.

Other then that, I agree they are nice radios and even include heaters 
in them to help maintain temperatures above freezing during winter time 
so that ice buildup doesn't cause a problem.
