Hello, hope you are well.
I have used T and K brackets to mount my Sirio SD 1300 Discone antenna onto two sections of 1.5m steel poles.
The Antenna is about 1 meter above the roof line but hums quite loud on occasions in light wind. This runs down the mast through the brackets and into the brick work of my house which is quite loud.
I have padded the antenna U bolts to the mast using damping material and also the same for the U bolts that mount the mast to the T and K brackets. I have also filled the mast poles with expanding foam. None of the above has worked so was going to try someones suggestion of using a bicycle inner tube over the cone elements but wondered if anybody had a more elegant suggestion.
Thanks in advance
