In spring 2019 I was asked to build an antenna which should be similar to equipment which is used by US Army and what more it should work.
After some research through sources of US military contracts and pictures there was a hot candidate for MILSAT or SATCOM antenna build: AV 2040 UHF Satellite Communication (SATCOM) Antenna from ULTRALife corporation 
There are STL  and OBJ  files for anyone who would like to print own atenna. The design is for 449,550 MHz but by adjusting lengths of active parts of the antenna it can be tunder in wide range, see below on Fig. 5
There are three formulas considering f as frequency in Hz need to be calculated to get three dimensions which are mandatory for best results:
red = (299792458 / f / 2) * 0.92 [meters] blue = red * 1.05 [meters] green = 299792458 / f * 0.225 [meters]
