I used a rhombic in the 70s while on contract TDY at Hill AFB, Utah [AGA5HI -
USAF MARS].

It was point to point from Utah to SE Asia [Vietnam War] and approximately 5
wavelengths per leg on 19 MHz and about 40 feet high [guess ... near top of
telephone poles].

It supported the SE Asia phone patch net [USAF MARS]. The USAF had LOTS of land
for the antenna.

We later switched to a Log Periodic as more versatile.

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?
