The EMCO Bilog Clamp is a mount accessory and is manufactured from non-conductive material to minimise RF influence.
This device has been engineered for supporting some of the Chase Bilog Antennas. It screws onto the standard 5.2cm (2 Inch) boom mounts. There is no rotation so the whole boom would have to rotate for polarization changes. The colour differentiates between the EMCO & Chase Bilog/LPs, due to the width of flange.
