seems a hamilton with long ground lead could achieve these field strengths but i refer to this reply here http://part15.us/node/2937 that even at excessive field strengths a hamilton turned all the way up with a full size tower just will not be able to do much damage to even the lowest power licensed facility. ask those with night time authorizations running 20 watts or so how far that signal gets. a hamilton turned all the way up is capable of 800mW with no asymetry and it runs class C? meaning you actually apply maybe a 3rd of that to the antenna/tuning system? ninus system losses? so lets face it, a hamilton, procaster, sstran or other 100mW input am tx even into a full 1/4 wave over 120 radials is just not going to offer any interference potential to even the lowest power licensed broadcaster. there are dimmers, computers, stop lights, etc that put out more RF hash then even 100mW to a full 1/4 wave. so i logic that the ground lead rules are outdated and should either be eliminated officially or just un officially by non enforcement. i agree 100mW is generous but they should go back to the original interpretation that “ground lead” meant from tx chassis to whatever structure the system is mounted to and not to earth ground. it worked out nice everyone was happy. was a nice compromise. we should go back to that.
