@neauoire Last time we talked about this I might have mentioned ComAnt directional antennas, did you consider that? I combined one with Teltonika 4G router on a carbon fiber mast before my far away place received fiber. Looking now it's so expensive though... also hard to direct the antenna at the top of the mast... hm
@tinspin yeah I have collected a couple of documents about it, but it's not really practicable on our small boat and especially the way we do certain things. Some people use non-directional Shakespears-type antennas to extend their range, but even that is troublesome to negotiate on Pino safely.
