Yes, Definitely drill the holeI have that antenna on two of my vehicles with the mag. Thinking about drilling the hole on one of them. I have been looking at this one:
Sirio Telflon RG303 Coax Cable (4 meter) -- 2000 Watts [rg303] - $42.00 : Sirio Antenna, High Performance Antenna Made in Italy
Sirio Antenna Sirio Telflon RG303 Coax Cable (4 meter) -- 2000 Watts [rg303] - Sirio Telflon Coax RG303, 4 meters, for max 2000 Watts, to use with Sirio Turbo-5000 and Performer-5000.www.sirio.store
I think it is the correct mount, but it looks like it is missing something?

Same.I use the Sirio P5000 mag mount on the roof of my truck and works well. Better than the Wilson 1000 I had there.
