The N3FJZ antenna system. 80
The N3FJZ antenna system. 80 meter full wave square horizontal loop feed by 600 ohm ladder line from link coupled balanced tuner. Height above ground ranges from 10 to 25 feet (3 to 7.5 meters). RF is probably absorbed by ground, what's left goes straight up perhaps.
Schematic and other details:

I've made one contact with KB6KPK in Orange California using 50 watts on 40m SSB. Routinely make 40M SSB contacts to PLAINFIELD IL, New York state, Georgia, Southeast Canada, Maine, Vermont, New Hampshire, etc.
o Wire for ladder line and loop: DX Engineering DXE-ANTW-500 - DX Premium Antenna Wire
o Spreaders and insulating tubes for ladder line: Zareba IT50 Insult Tube, 50-Feet (search Amazon, TSC, Googls, etc.)
o Insulators: DX engineering Alpha Delta End Insulators.
o Balanced link coupled tuner: Scratch built homebrew, inspired by Johnson matchbox, Annecke, Antek UT-1, etc.
