Back when I was working with several radio sites, we were using 2" wide flat copper ground strap; because it was supposedly lower impedance than wire ground conductors. [Lightening as you know is NOT a DC impulse.] Mmmm. At what frequencies do flat strap conductors stop being lower impedance than round conductors or vice-versa?
?
On the other hand, flat strap in the open air outdoors would tend to flap and twist in the wind, making it unsuitable for an outdoors antenna.
