If I understand correctly line of sight, and height, are key to extending how far you can transmit. What tricks have others used to gain height around their area? I’m kicking around a lot of ideas that range from a flagpole in my backyard to asking the local musicality if I can mount a node on our water tower. What has given you the most success for extending range in a tricky area?
Reach out to your local ham group - almost certainly there is one - and almost more certainly theres a nerd with a giant tower they have access to that would love to talk your ear off and for you to tolerate their antics - and in exchange for that theyll mount your node on their tower
From what I’ve seen, if a local municipality isn’t down to let you put up a node, people will usually erect a pole at the best spot the legally can. Used radio towers become hot commodities in the right areas
