    A #1 best antennas you should have hands down
  

*by D***S on Reviewed in the United States 🇺🇸 on January 30, 2020*

As I've said before Sirio blows them all away I went back to the Wilson 5000 because somebody stole my load and Stinger of my Turbo 5000 and i happened to have a wilson load and stinger but i was browsing the net about sirios and seen the megawatt 4000, bought this only because its a satin black and chrome and looks fantastic on my 07 blacked out Explorer. As far as performance unbelievably fantastic as with the 2 turbo 5000 , and my base station gain master antenna thats by far the best base antenna hands down i kill the locals and hear stations I've never heard before , I've had A99 maco 5/8 and imax We have a new king of antennas and its Sirio from D&JRadio best service ever
