The EMCH-LPM is a mount accessory and is manufactured from non-conductive material to minimise RF influence.
This device has been engineered for EMCO Log Periodic antennas. It screws onto the standard 5.2cm (2 Inch) mast boom. It will allow the LP antenna to rotate through 90 degrees. The colour differentiates between the EMCO & Chase Bilog/LPs due to the width of tongue.
