Antennas that solve all kinds of problems

At ALCAD, we have one guiding principle when developing an antenna: it must solve problems, no matter how challenging.

We go beyond high gain, focusing on the high quality of materials used, excellent front-to-back ratio, and vertical-horizontal polarisation change.


Terrestrial antennas

We offer three ranges of terrestrial antennas: NEO (UHF), MX (UHF), BU (UHF).

NEO: the highest gain on the market
NEO antennas are ALCAD's top-of-the-line range, providing the best reception of DTT channels and the highest gain on the market (18 dBi).

Designed to cover the UHF band up to 790 MHz, they reject the LTE mobile phone band. Easy to assemble and adjust, they ensure maximum robustness and safety during installation.

Their attractive design perfectly reflects the excellent electrical and mechanical qualities of the antenna. They are ideal for digital and analogue terrestrial TV installations, both communal and individual, where LTE band rejection and high gain and directivity are required.

The reflectors prevent interference from signals received from the rear of the antenna.

Easy assembly, no tools required.

MX: quad array antennas

MX antennas feature a quad array for very high gain. Designed to cover the UHF band up to 790 MHz, rejecting the LTE mobile phone band.

Easy and quick to assemble. All elements are pre-assembled, and no tools are needed for installation.

BU: dual array antennas
BU antennas with dual array cover the full range of gains. Designed to cover the UHF band up to 790 MHz, rejecting the LTE mobile phone band.

Easy and quick to assemble. All elements are pre-assembled, and no tools are needed for installation.



Satellite dishes

Offset-type antennas, made from electro-galvanised steel, fibre, and aluminium, ranging from Ø60 cm to Ø120 cm.

An offset antenna is a type of satellite dish, though not strictly parabolic in shape. Its shape is a section of an oval-shaped parabolic reflector. The surface of the antenna is oval and asymmetrical (ellipse).

The focal point is not mounted in the centre of the dish but offset to one side. This technology's advantage is that the antenna surface is not shadowed by the LNB (from the satellite's perspective).




The LNB (Low Noise Block) is the device located at the focus of the satellite dish, responsible for adapting the signal received from the satellite and distributing it via coaxial cable throughout the installation.

Since the downlink transmission frequencies from the satellite are too high to be transmitted directly by coaxial cable, an LNB is necessary to convert these frequencies to levels suitable for coaxial cable.

ALCAD offers various types of LNBs to meet all needs, from individual users to large installations with multiswitches:

  • LNB Single: A single-output LNB for installation towards a single receiver. This type has a low noise figure and phase noise, commonly used in domestic and individual installations.
  • LNB Twin: Designed to handle the need for two LNBs on a single satellite dish. The long neck allows close placement of the LNBs to access satellites that are close together in their orbital position.
  • LNB Quad: Designed to handle the need for four LNBs on a single satellite dish. Its four outputs can be connected directly to different receivers.
  • LNB Quattro: This type of LNB has four outputs with different polarities (vertical high, vertical low, horizontal high, and horizontal low), used for multiswitch installations.


Preamplifiers, multiplexers, and mast filters

A range of UHF preamplifiers for antenna boxes (BU, MX, and NEO-04x ranges), powered through the coaxial cable. In addition to amplifying signals, they adapt the antenna's impedance from 300 ohms to 75 ohms. The noise figure is extremely low, ensuring signal amplification without quality loss.

Applications: analogue terrestrial TV installations, communal or individual, where reception levels are very weak. Installed in place of the antenna's balun, amplifying the signal before installation attenuations degrade it, achieving the best possible signal-to-noise ratio.

Multiplexers are passive elements that combine signals from different antennas or sources into a single output (cable).

As a transmission element, it must prevent unwanted interactions between connected devices.



Masts, towers, and mechanical accessories

We offer a wide variety of mechanical accessories for antenna installation, such as towers, masts, telescopic masts, arms, brackets, guy wires, satellite dish supports, and chimney clamps.
