Relevance was vertical to horizontal for local comms??? within 100 miles,, not going to draw pictures here or come back explain every statement.
Why use 40 meters for local comms,,10 and 12 work fine,,load the wire up and talk.
Or put a fan dipole with those bands on it.
3.865 around 0830 to 0900 Z should hear mouth of the Midwest W9FNB,,or Charles N9CED,, both big booming stations running low slung wire antennas.
Local comms of 40 meters 5 mile apart,,connect to the dummy load run 100 watts,,you might be surprised.
I have talked to New Smyrna beach of my dummy load,,was working on an old FT 101 on the bench and started receiving a loud signal ,,I was connected to my dummy load.. SO I replied to his CQ,,he came back,,go figure
