When I upgraded some equipment they came by and actually replaced the AT9 with the AU9 & me not knowing any different told them to go ahead. I actually liked the AT9-sidecar & think it might have handled the snow fade better though to be fair it was on a temporary non-penetrating roof mount shielded from the elements. They just left the AT9, the mount & the 4x8 switch for me to do as I please..lol.
Jim, I'd take the Magic Dome off your hands (It's like $25) as I use a lot of it around the marina but I don't think it's worth the cost of shipping here, plus I have a few cans anyway (thanks for offering). Maybe it's just psychological for me, but the thought of me on my roof & on a ladder spraying my dish is making me laugh my azz off anymore.
Wait until you see my light contraption.
