Hallo
some more details:
Frequencyband:800-813 MHz and 726-1001 MHz
Picture of older version (used on MiG-21bis-sau since 1975 and on MiG-23)

The antenna is 25 cm long and the reflector is 18 cm wide.
You can see an dielectric stripe in the middle of the dipole. A second one is at the opposite side of the shaft. I
have no idea about the stripe's function.
If I find more details about the antenna-function in my old notes, i will post it here.
The new version of the antenna is in use sice the 1980s and has only a new dipol shape.
The following picture shows the new antenna-version integrated into the pitot of a Su-25 bomber.

This demonstrates that the nose cone of normal RSBN-antennas has no special function.

Post by lewradarAs simple as that? The bar must be a reflector then?
Thanks, Sprut

Post by unknownThis is not an IFF antenna, but the rear aerial for the short range navigation
system A320 (known as RSBN). A second antenna of same type is located
below the radar nose.
It is basicly a normal dipol antenna (L-band). The bended shape is responsible
for the antenna pattern, that has to cover a halve spere.

does anyone have a reference for an explanation of how that forked aerial
"swift rod" works??
