Help putting radar stern mast system together

[CourageousME]

I'm having a hard time putting together my stern pole/radar mast. I've been looking at major manufacturers and I just can't seem to find a system that works. Perhaps you can shed some light, doesn't seem to be too fancy or special

1. 3" mast pole in white. Approx 8-10 feet long. I just need a pole, no supports etc.

2. Top mount for a Sailor 250 fleet broadband antenna.

3. Front of the pole/facing the bow: self leveling mount for Garmin 24" HD Radome

4. Off either side of the top of the mast, is like an accessory mount of some sort. One side will have my AIS antenna, the other side my dedicated GPS external antenna. I don't care if they mount to poles that curve up and besides the Satcom unit or just are mounted to a wing type of device.

I drew a horrible picture to help and also found something similar. I'll attach that too
