I would not want to stand near a feedhorn connected to a 1200W signal source. Toasty... I asked my eye doctor about cataracts caused by microwave exposure. He did some research and came up with nothing but I swear I read many WWII radar techs got cataracts.

You need dual diversity dishes on each end and they have to be immense. There's lots of old abandoned troposcatter stuff in northern Alaska and the Yukon, Nunavut which provided remote-site radar data links to the SAGE network. google image search alaska tropo scatter: https://www.google.com/search?q=alaska+tropo+scatter&num=100&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjFq-7KrOTKAhUP6WMKHcSXDTgQ_AUIBygB&biw=1067&bih=730 http://www.comtechsystems.com/products-systems/troposcatter-hardware/ http://www.comtechsystems.com/product/cs67200i-modem/ you thought some licensed band 6 GHz stuff had a high EIRP with 8' dishes... Imagine putting a 1200W amplifier (which is about a 4000W electrical load, a lot is lost to heat) into the feed of a 25 foot dish feed.
