over 100 mhz used and with more power to jam but also i have some circuits to beef it up and its not directional as even the ac wiring in the whole house soaks it up so i can monitor it in the ac feilds even in a rf dead spot i tapped the high power rf output and used it the same way or better as you would with a step up transformer and i dont use an areal i use a rf core which slides in and out to adjust the out put power it just a power rf amp unmodulated and it goes everywhere so i have it set to pulsate and emit over 100mhz power unmodulated power in 50 hertz bursts and what it dose to the output would be like what a step up transformer dose with its dc input and thats double or more the power as i used part of a tesla free energy from air circuit in it to and ive seen what it has attracted as i saw the craft outside at night slowly drifting over my bedroom end of the house and also other things gliding above and along the gutter above my room outside at night , im still transmitting so much energy that even a swinging arm pendulum clock with a dead battery on the opposite side of the wall from my experimenters room started working again by itself from the charge induced from the energy of my experiment so its the high frequency unmodulated powerful rf bursts that seem to attract them, ufo activity didnt just happen for nothing my experiment may of tapped into something they can receive and so investigated it and stepping up the rf output is adding to what it dose to in a mystery way, and i used powerful 5mm diameter magnetic bearing bands around my rf out put coils at the end no one dose that as they dont think outside the box enough to even do it it acts as a rf ground to the coils rf output so it circulates, never mentioned it after all these years but the energy output disabled the ac smart meter outside the front of the house to
