I think this has pointed out a gap in the product line. I’m not trying to save costs or re-use something - I’m trying to design a solution that uses two or more HD1 domes + WiFi WAN as WAN sources and takes advantage of the Peplink features. Having a core router that can provide PoE to various sources, or works with the SIM Injector more dynamically would be a great solution for this setup.
For Option 1, I appreciate the suggestions of an MBX but the whole point of what I’m trying to do is avoid running antenna cables on boats. Folks seem to think that it’s easy to do this, and it’s not. Not only is it very difficult on most vessels, it usually requires 20+ feet of cable alone just to get to a suitable antenna location, usually more, even on smaller vessels. And those antenna cables are running near other interference sources, so by the time you run the cabling, you’ve negated a large portion of the antenna gain!
An alternative is to have very short cable runs and place the router near the antennas. This requires custom enclosures in most cases, and they are hard to reach, difficult to maintain, and have very high temperatures. It can be done, but it usually scares people away when you start talking about custom enclosures or fiberglass work.
The Dome is a perfect product for a boat - all of the radios and antennas are self contained, it has an amazing mounting solution, and it only needs a single ethernet cable which really cannot be that affected by distance or interference if done correctly.
For Option 2, both the Balance 305 and SDX require AC power and have very low high temp thresholds. It is always preferred to use DC power on boats since it is already likely being converted internally in the product, and is inefficient to use AC. I’m also going to guess that the SDX is going to be very expensive, given the other products it is listed with, and will likely push this solution out of the realm of reasonable.
For Option 3 - it looks like you’re proposing two cables from the SIM injector to the Balance? Or are you suggesting this is using VLAN tags? This is a bit different than the previous suggestion. Can you have the SIM injector connected to two different WAN ports on a Balance, even with the same subnet? Or are you suggesting some sort of VLAN tag situation?
