I have a unique opportunity to add a node at the Tower LNB ring. However I’m struggling to source a Meshtastic gateway that meets the requirements I’v been given. Any help would be appreciated.

1. Power will be provided over 48v POE ONLY
2. Remote management is a must, consider both internet provided over ethernet and 4G/LTE as backup (fw updates)
3. Maximum 5db gain antenna can be used positioned on the LNB ring facing N-NW, must not exceed 1400mm in length
4. Must be tuned for exactly 915mhz (l’m thinking cavity filter) to help with Rx.
5. Enclosure and antenna must be pole mounted
6. Absolutely no wifi 2.4 or 5ghz
7. 500CND budget I’d like a set it and forget it approach. ls it even worth it?
