Hi all. My first time posting. I have a nice discone antenna but beginning to wonder about interference and large bodies of water. I live in Alaska presently on the job at a shipyard in my RV, right on the bay. I'm stuck here for the next 4 months and have my sdr gear with me for entertainment. My question(s) are does a large body of water help or hinder reception? And also, being surrounded by dry-docked boats on three sides (aluminum and steel), , shipping containers, and all manners of heavy equipment in the boneyard here, will that also mess me up? My antenna is about 70 feet elevation on a tall security light mast. Just hoping to get some ideas before getting the crane guy to hoist me up in a basket again to move it. Thanks. Greetings from Seward, Alaska.
