Antenna Y5 VHFγ was developed by American wireless enthusiast K8CC using computer optimizer and has the highest technical capabilities (gain and low fringe radiation) peculiar to five-component antennas.
After the number of field studies being conducted our engineers can confirm this. Such antenna provides stable radio communication at distances up to 80 km long at cross-country.
Highly-directional pattern enables to use antenna as receiving antenna in order to "turn aside" from interference, since front/side attenuation constitutes only 20dB!
