Default Rhombics

Before I go to the trouble of putting up a rhombic, I've been using NEC to
get an idea of the gain, radiation angle etc for various leg lengths. It
all looks very promising on the computer but I'd be interested in
real-world experiences. For example, how well does the real antenna
approach the PC simulation when various factors like wire sag, uneven
ground, presence of trees and shrubbery?

Back in the 70s a friend and I put up a rhombic antenna in a pecan orchard
on 11M. If I remember correctly each leg was about 8 wl long. At first we
thought we had done something wrong but then we began regularing talking
with guy about 45 miles away west of Tifton Ga.that we could not talk to on
his quad. Apparently the beam width is so narrow it makes it impractical
except for point to point comunication.
