Televes Satellite Antenna

Televes satellite antenna - ISD aluminium offset satellite dishes

The ISD series satellite antennas use an offset design with an aluminium reflector and stainless steel screws. The mechanical structure includes a flexible LNB holder and clamp made from special glass-fibre-reinforced polymer, an aluminium arm, and a Zamak clamp and support. Two U-bolts are included for mounting. The aluminium reflector and stainless steel screws provide resistance to corrosion.

Which satellite frequency range does the ISD series cover?

The ISD 630 and ISD 830 both operate in the 10.7-12.75 GHz frequency range for satellite signal reception. One of the key technical differences between the two sizes is gain: the ISD 630 provides 35.5 dBi and the ISD 830 provides 38 dBi at 11.75 GHz. The offset angle is 26.2 degrees for the ISD 630 and 26.6 degrees for the ISD 830. Both series use a 40 mm diameter LNB holder.

How does the Televes ISD 830 satellite dish differ?

The ISD 830 uses a larger reflector measuring 833 mm in height and 747 mm in width, while the overall product depth is 660 mm. Its gain is 38 dBi at 11.75 GHz and its offset angle is 26.6 degrees. The main product weight is 2131 g. Most listed versions have an elevation range of 0-90 degrees, while Ref. 793103 is specified with a 20-60 degree range. Wind load is 499.2 N at 130 km/h and 686.4 N at 150 km/h.

Aluminium reflector and corrosion-resistant construction

The ISD satellite antennas use an aluminium reflector and stainless steel screws. The LNB holder and clamp are made from special glass-fibre-reinforced polymer. The glass-fibre-reinforced plastic is resistant to corrosion, non-magnetic, flame-resistant and electrically insulating. Its low weight supports installation, while its flexibility improves the mechanical behaviour of the material under adverse weather conditions.

How are the LNB and coaxial cable positioned?

The LNB is installed in the 40 mm diameter holder, which can hold the LNB in position during installation without the use of a screw. A hex key for tightening the nut is integrated into the LNB holder. The internal design of the aluminium support arm allows the coaxial cable routing to be concealed inside the arm. The arm is installed using a single screw, while the reflector support connects to the elevation mechanism.

Mast mounting, elevation and mechanical installation

The ISD 630 and ISD 830 can be mounted on masts with a diameter of 20-60 mm. The mounting structure uses a Zamak clamp and support together with two U-bolts. The screws in the support are pre-assembled and protected against corrosion. The reflector mounting is supported by the design of the fixing holes, while the aluminium arm requires one screw for installation. The elevation mechanism is used to adjust the satellite dish.

Televes ISD satellite antenna advantages and key considerations

Advantages:

• Aluminium reflector and stainless steel screws
• Glass-fibre-reinforced polymer LNB holder and clamp
• Coaxial cable can be routed inside the aluminium support arm
• Integrated hex key in the LNB holder
• Mounting on masts with a diameter of 20-60 mm
• Orange, white and graphite colour versions within the product family

Key considerations: the ISD 630 and ISD 830 differ in reflector size, gain, offset angle, weight and wind load values. The documented specifications of the specific ISD version should therefore be considered when selecting the appropriate size.
