Review on SP 3FE Eliminator Transformer Applications Antenna（Frequency by Seth Gomez

We had a "hum" ground loop from the TV antenna/FM tuner/audio system on the roof. The antenna is grounded at two different points. The GROWORD isolator worked great, completely removing the 'hum' from the FM tuner and all other input sources. This saved the "guy" time/effort!/$$ to run 100 feet of new wire to reconfigure the antenna ground circuit (which may or may not have solved the problem!) AND NO trips underground !
