Trailer hitch mast mount

I designed this this mast mount because I wanted to be able to rapidly deploy a mast mounted antenna in a location that didn't have other supports available.

Design Criteria:
• When not in use fit inside vehicle
• Be able to handle large to small diameter masts
• One person should be able to safely put up mast
• Should not require user to lift mast through top clamp
• Even if collar is loosened, it shouldn't slide down mast
• Should be a no-tools deployment
• Minimize moving parts
• Can open window portion of hatch while mount is in place

The following was done to meet design goals:
• Offset T-handled stainless bolts accommadate various sizes of masts. And permit a No-Tools securing of mast.
• "Tab" to keep collar in place

To deploy this mast mount:
• Put the bottom collar on the mount first
• Secure the mount in the hitch
• Make sure the bolts are loose on the bottom collar
• Put your antenna on the mast, pulley for wire support, etc.
• Slide the top collar onto the mast
• Place the end of mast on top of the bottom collar
• Hold the smooth side of the collar in your hand, supporting the mast
• Support the mast with your other hand as well.
• Erect the mast keeping the bottom in the mast mount
• As you get near vertical the mast should drop to the ground inside the bottom collar
• Slide the top collar down into it's tab, making sure to orient it properly.
• Tighten down the top collar
• Tighten down the bottom collar
• Done!

After having practiced with this mast mount, I would likely have the bottom collar welded to the rest of the frame. Although that doesn't lend itself well to transport. So, it's a toss up.
