I just ran some quick numbers, and a unlicenced 20mile link like that would be possible, but I wouldn't sell it.: 1.75mw -> 36dBi antenna -> freespace -> 36dBi antenna -> reciever + mis losses, has an EIRP of about 3.9 watts (legal). You'd have about 15db of link margin, and that's much too little for a reliable link IMO.
That's why I suggested two 10 mile links. :-) There are a large number of people in the 10-14 mile range with reliable links, and very few people pushing further. That said, some guy in NZ got around 35 miles as I recall using off the shelf parts. It no doubt exceeded FCC regs though, but that's not an issue for him. -- Leo Bicknell - bicknell () ufp org Systems Engineer - Internetworking Engineer - CCIE 3440 Read TMBG List - tmbg-list-request () tmbg org, www.tmbg.org
