End fed wires have been my "go to" antenna for years at Field Days and Boy Scout Jamboree on the air, demonstrating ham radio at schools...
A simple "L" section tuner and a wire to a convenient high point gets you on the air. A coil of coax (10-20 turns about 4-5 inch diameter" between the "L" section and the rig tames stray RF reasonably well, but in later years I preferred the line isolator from Radioworks.
