Those of you with external antennas, do you use Lightning strike/surge protection to avoid damages to your equipment/house wiring if the lightning should chose to strike your ADS-B Antenna ?

If yes, how is this protection made?

Thank you!

If a lightning chose to strike your antenna it was not that important whether you fed your system via PoE or whatever else. More likely, everything will get fried, no matter whether attached directly or in close proximity to the line antenna to best ground connection, with that line not necessarily following strictly a conductive path. Lightning currents like straight paths and are able to change conductivity of several substances dramatically in case there is just a short partial path missing for accomplishing the straight path.
Lightning protection takes place by not letting hit a lightning your antenna. That is what lightning arresters are made for. They are not ment to get build by amateurs and typically keep apart from other conductive installations but earth electrodes / heavy groundings. They are put in an preferably straight path from tip to grounding.
In case you are lucky with an up to date lightning protection installation you can add over voltage protection directly to your electronic components. That kind of protection never will gain ligthning protection level. Instead this will short severe over voltage induced by nearby lightning strike up to a certain amount.
Better pay for experience by hiring professionals than trying by experiment when it comes to installing lightning arresters https://www.streamer-electric.com/products/lightning-protection/induced-lightning/sai10z
