DESCRIPTION
1/4 λ wide-band antenna for base station service covering the frequency range of 145-175
MHz. It as been developped according to the most modern technologies to assure a perfect
protection against the worst atmospheric climates and to get the best performance. It is entirely
made of aluminium to assure strength and robustness and its radial whip is earthed. Its 30 MHz
bandwidth makes it particularly recommended for relay stations or two-party systems.
