Don't think we have to feel too bad for them..$1M might sounds like a large fine to us but for a company who did over $500M it was probably a business decision to ignore the FCC regulations as a calc

You might think about placing some spokes at the top of the tower to act as a capacity hat. We recently installed a 50ft center loaded helical antenna for our county emergency 7X24 AM 1700 station. T

I run 7 watts into a 50ft center-loaded helical and use a common MFJ tuner to match the input. I have gotten good reports from stations as far as Ontario, Canada. He might do just fine with 14 watts.

I wonder what happened to those 1,000s of plasma volts that were supposed to leap out of the top of the coil and cause massive RFI to your neighbors, haha. I'll look for you on 1920 at 10pm tonight.
