The model UHA 9105 Antenna features an aerial head with a Teflon coax BALUN, ensuring symmetry up to 1 GHz, and two tubes slotted at their ends and secured by hexagonal nuts. A tuned Half-Wave Dipole Antenna is considered as a reference for measuring field strength and generating defined UHF electromagnetic fields (up to 10 watts ERP).
Without the telescopic inserts, the total length of the tube elements is 120 mm. With the telescopic elements, the length ranges from 173 mm to 520 mm. The antenna offers high bandwidth due to the large diameter-to-length ratio, particularly above 800 MHz.
The Antenna Holder is a 475 mm tube with a diameter of 22 mm and an indexing ring, secured with 3 mm screws. This setup ensures a fixed position with the elements in either a vertical or horizontal plane when inserted into the movable antenna holding box of the detachable mast system model AM 910 (for antenna heights ranging from 0.4 m to 4 m.).
