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.
