AS3900 SINCGARS Vehicle Mount Antenna
The Military calls it broadband Vehicular Whip Antenna it is certainly that Broadband
Center loaded mobile HF vertical

Construction of a balcony antenna for Hf
I wound 2 wires with a diameter of 1.6 mm copper at the same time on a PVC tube with a diameter of 75 mm and a length of 180 mm
DK3 Screwdriver Antenna
The DK3 is probably the best mobile antenna for hf. It is also well known as the screwdriver antenna. It works on all hf bands 10m-160m without changing the whip
