The FVC4.5 colinear antenna is a very robust, high strength omni-directional antenna that can withstand the harshest environmental conditions.The brass radiating elements plus phasing coil are treated with a plasfilm coating then housed in a heavy wall fibreglass tube which is totally weather sealed. The antennas are most suited for mast head fixing, but can also be side mounted onto structures to give some degree of directional characteristics. Colinear stand-off brackets can be supplied ex-stock.
