DESCRIPTION
3/4 λ VHF antenna for base station service made of high quality materials to get the best perfor-
mance and the maximum efficiency. It is completely manufactured with aluminium tubes and
nylon for its great robustness and it is supplied with a solid steel bracket for an easy and safe
installation. Its Gamma Match feed makes it earthed for a perfect protection against the static
discharges. In the mentioned range of frequencies, adjustments are not required. Simple and
strong it is particurly recommended for a professional use.
