I have Morgan M-303 Suppressors on my antennas and have no problems on any band. ?I’m using an FT-DX10 to an HF-AUTO tuner with a Hexbeam and Endfed antennas. ?All work great through the Morgan’s. ?I also use a Morgan device for my rotator. ?I do have a fairly extensive ground system in and outside the house. ?Some pictures on my QRZ.com page. ?Hope this helps. ?73, Jerry K9TRX
