Mast mount options

I would like to add a WiFi/cellular antenna. I see three options...

1) screw/rivet a mount to the mast (such as: 4366-R Stainless Steel Mast Mount Shakespeare Marine Antennas or https://glomex.us/portfolio-items/v9173/ which is similar to my TV antenna mount),
2) find a mount like the one my spotlight is mounted on to bolt onto the existing tab opposite the spotlight (can't find anything like this but maybe the antenna should be higher up for optimal signal, especially because we have a large tide swing and the extra couple feet might make a difference),
3) some how extend the mount at the top of my mast where my wind transducer and VHF antenna are, either adding +1 to either side, or even both sides (probably not to the side of the wind transducer as it may cause it not to work).

Looking for additional options or thoughts on the above 3 options. Short of riveting a mount to my mast or having something custom built, any one have any ideas on a pre-made mount that can be used in conjunction with options 2 or 3 above? How hard is it to rivet? Can most electronics installers do it?

Personally I would try to go with option 2. Mounting bracket is already on the mast, should be easy to start from there.

Any idea where I can find a pre-made mount that would be compatible? I am getting estimates of $300-ish and 4-6 weeks lead time to have something custom fabricated...

For option 3, I'd simply replace that horizontal plate with a longer one, since it appears to be bolted onto the tab that's welded to the mast. That's something you can do yourself.

But where can I purchase a "longer one"? That is what I have been searching for...

Couldn't you bolt this to the tab sticking off your mast ? ( You'll probably have to drill holes but that's not to hard )

Aluminium flat bar/strip stock from onlinemetals.com. 6061 T6 1/2" x 4" x 2 ft long is less than $30 (plus shipping), but I'm just guessing at what you need.

On my mast, I used aluminum flat bar, 2” x 3/8” that you find being used to mount on helm seat arm rests. Heck, I might even have one laying around here. Could be drilled to bolt on to mast, hose clamped with SS band, or u-bolt bracketed with SS exhaust clamps.

Mystery -

I would add an extended composite material mounting plate to the spot light plate.

Might be the simple solution.........

Plenty of bolt support there. (Also get ride of the POS factory spotlight!!!)

Good luck
