[BC] LPAM (was Smallest AM Radiator/TIS)

Fri Jul 14 10:41:17 CDT 2006

Well WSJL in Villas NJ(near the wildwoods) Ran a Hamilton mounted on a 50ft
Rohn 25g Tower. he had as much of a radial system as his property size would
allow. he bonded them to his chainlink fence and the base of the tower. he
got out during the daytime solid for 3 miles fringe out to 10 miles. he
passed FCC inspection by the philly, pa feild agents.
He has his instrucions posted here....
http://www.am1000rangemaster.com/downloads.html most users just follow
keith's instructions. I have come up with a optimal site design that should
pass. it is located here... http://www.part15.us/node/895/

Robert,
   Can you run a "full ground" system with his box?

the keith hamilton units require a ground and it is stated in the
instructions. it was certified at a FCC Testing Lab along with those
instructions for type acceptance under part 15. their is over 1500
rangemaster units running across the country using this configuration
and
passing FCC inspection.
