Panorama Antennas Tetra Base Antenna

Panorama Antennas TETRA base antenna - ODP-TET-8B

The ODP-TET-8B is part of the ODP offset dipole antenna range. Its lightweight construction is designed for fixed radio terminals and straightforward installation. It can be used as a remote antenna solution for network extension or coverage improvement. The antenna is supplied with an integrated coaxial cable and is suitable for both indoor and outdoor installation. The wall-mounting plate contains four fixing holes.

What frequency range does the ODP-TET-8B TETRA antenna operate in?

The ODP-TET-8B operates in the 380-430 MHz frequency range and provides 2 dBi gain. The product is designed for TETRA radio communication and uses a BNC male connector on the cable side. The integrated 8 m RG58CU coaxial cable forms part of the antenna. When selecting the installation location, the cable route should also be considered: the shortest practical cable path to the radio terminal reduces cable attenuation.

Offset dipole design for fixed radio terminals

Assembly of the antenna includes fitting two antenna elements. The radiating whip must be inserted into the socket marked TOP and tightened securely. The helical counterpoise element must be fixed into the lower socket. During installation, the area around the upper radiating element should be kept as free from obstructions as possible. For wall mounting, the antenna must be installed in a vertical position.

How can the Panorama Antennas TETRA antenna be mounted on a wall or mast?

The ODP antenna can be mounted on a flat vertical surface or on a mast with a diameter of 32-54 mm. For wall installation, the mounting plate at the end of the dipole arm can be used to mark the fixing hole positions. Suitable screws and wall plugs must be used; these are not supplied. The mounting plate has four holes, each with a diameter of 5.1 mm. The cable must exit from the rear of the arm in the correct direction.

For mast installation, the dipole arm can be fixed directly to the mast using self-tapping screws or heavy-duty UV-resistant nylon cable ties. The permitted mast diameter is 32-54 mm. The upper radiating element should be positioned where there are no direct obstructions around it whenever possible.

8 metre RG58CU coaxial cable and BNC connection

The ODP-TET-8B is supplied with an integrated 8 m RG58CU coaxial cable terminated with a BNC male connector. The cable should be routed away from the antenna and secured at regular intervals along its full length. Cable clips must be sized so that they do not compress the cable. If cable ties are used, they must not be overtightened.

What requirements apply to cable routing and commissioning?

When routing the cable into a building or enclosed space, a drip loop must be formed so that water running along the cable cannot enter through the opening. If an antenna is not pre-terminated, a suitable connector must be fitted. The ODP-TET-8B is supplied with a BNC male connector. During commissioning, a VSWR measurement must be performed, followed by an on-air check after connecting the antenna to the radio terminal.

Indoor and outdoor antenna installation

The ODP-TET-8B can be installed both indoors and outdoors and has a waterproof construction. For outdoor installation, the drip loop at the cable entry point is intended to prevent water from entering along the cable. At locations exposed to lightning, the use of an in-line surge arrestor should be considered. The antenna is electrically conductive and must not be installed where the antenna itself or the installer could come into contact with overhead power lines.

RF safety and RoHS requirements

During operation, the antenna must be positioned so that no person is closer than 30 cm to it. Installation must be carried out by a suitably qualified person in accordance with local laws and regulations. The product's RoHS 2 compliance relates to Directive 2011/65/EU and its subsequent amendments. Waste electrical and electronic equipment must be collected separately for recycling and must not be disposed of with normal waste.
