Usually, a counterpoise system is used to provide an efficient earth plane. A radial earth plane for an antenna mounted on the roof-top of a building can be supplied by Codan (Codan part number 15-00159). If an earth plane, such as a counterpoise, cannot be provided for the antenna, an earth wire connected to a suitable earth stake can be used, but with reduced efficiency.
Such holes need only be large enough to allow the end of the cable with the smaller connector to pass through. Removing a connector should be a last resort. Externally, the cable and connectors need to be weatherproofed using self-amalgamating rubber tape. 3048 T UNED IPOLE NTENNA NSTALLATION...
Installation flowchart This flowchart provides a recommended sequence of tasks that describe how to install the 3048 Tuned Dipole Antenna with the 6 m mast that has been designed specifically for this tuner and antenna. NOTE: Interface specifications are provided if you are installing the tuner and antenna on your own mast.
In a rooftop installation, attach an anchor point to the roof using appropriate fasteners. Provide three more anchor points at 90° intervals on the 4 m radius from the centre of the base plate. 3048 T UNED IPOLE NTENNA NSTALLATION...
