New to the community here, and looking for advice on building a new system for a 52ft catamaran. It will be for a world cruiser, so need to be able to work with global frequencies. My main goal is to get decent internet further offshore or in a remote anchorage. Secondary goal would be to get fast speeds, but I don’t really have a need for redundancy like with the dual modems. I can manually switch sims if one network isn’t very good.
From my googling and reading of posts, it seems like there are two products that would work well for me: the Max Transit (Cat-18 or new 5G) or the Max HD Dome 1. I like the price, 5g capability, and simplicity of the Max Transit, but worried about the length of the antenna cable run to get it to a place where I can easily access the SIMs to switch them when I get to a new country. The Max HD Dome 1 seems like a good alternative with no signal loss over the run up the mast, but is more expensive and seems more complicated with a SIM injector and no built-in wifi capabilities.
I guess my question boils down to this - how important is the height of the antenna, and at what point does the signal loss in the cable runs negate the benefit of having an antenna mounted high up.
To put some concrete numbers out there, our options are either to put it on the spreaders (1m out on spreader + 10m to mast step + 3-4 for routing to modem = 15m run) Would it affect our distance much to put it lower on the mast somewhere, or even on the coach roof (~3-4m off the height of the water) On a related note, if we did the HD Dome 1, would putting it on the masthead improve range, or would that be chasing after diminishing returns? (mast height is 24m)
