SIST EN 300 631-1 V1.1.1:2003 is the SIST version of the ETSI European Standard EN 300 631-1 V1.1.1. It specifies antenna performance requirements for directional fixed-beam antennas used on point-to-point radio links in the 1 GHz to 3 GHz band, so manufacturers, operators, purchasers and test labs can choose and verify antennas for digital radio relay systems.

What does SIST EN 300 631-1 V1.1.1:2003 specify?

SIST EN 300 631-1 V1.1.1:2003 specifies standardised antennas for point-to-point digital radio relay systems in the 1 GHz to 3 GHz range. The document focuses on antenna performance for frequency coordination and practical system use.

What are the key requirements of SIST EN 300 631-1 V1.1.1:2003?

SIST EN 300 631-1 V1.1.1:2003 sets the main antenna limits through radiation pattern envelopes, XPD, gain and polarization. In practice, these are the parameters that determine whether an antenna is suitable for a given radio link and interference environment.

• Clause 4 ties the document to the fixed-service frequency plans in the named CEPT and ITU-R references. For users, that means the antenna has to fit the band plan used for the link.
• Clause 5 defines three antenna classes based on the interference environment: unlikely, low, and high interference potential. This helps planners match antenna sidelobe performance to the site.
• Clause 6.1 gives the Radiation Pattern Envelopes (RPEs) for classes 1 to 3. These envelopes are the masks the co-polar and cross-polar radiation patterns must fit, so they are central to lab checks and coordination studies.
• Clause 6.2 sets minimum Cross-Polar Discrimination (XPD) values by class and figure. For users, this supports better isolation between orthogonal polarisations and helps with spectrum reuse.
• Clause 6.3 sets minimum antenna gain by class. That matters in link budgets, because the gain determines how much directional performance can be assumed.
• Clause 6.4 requires antennas with radomes to meet the same RPE and XPD limits with the radome fitted. This means the finished antenna, not just the bare radiator, has to pass the performance check.
• Clause 6.5 requires a linearly polarized wave, single or dual. This is important for compatibility with the radio system design.
• Clause 6.6 adds an elevation RPE for class 1 antennas. That controls vertical radiation, which affects coordination where other paths or services may be nearby.

What terms does SIST EN 300 631-1 V1.1.1:2003 define?

SIST EN 300 631-1 V1.1.1:2003 defines the terms that describe antenna patterns and performance. These definitions make the measurement requirements readable and keep manufacturers and test labs aligned.

• Antenna - the part of the transmitting or receiving system that radiates or receives electromagnetic waves.
• Co-polar pattern - the radiation pattern measured with the reference antenna similarly polarized.
• Cross-polar pattern - the radiation pattern measured with the reference antenna orthogonally polarized.
• Cross-Polar Discrimination (XPD) - the difference between the co-polar main-beam peak and the maximum cross-polar signal over the stated angular range.
• Gain - the ratio of radiation intensity in a given direction to the intensity of an isotropic radiator.
• Radiation Pattern Envelope (RPE) - the envelope below which the radiation pattern shall fit.
• Radome - a dielectric cover that protects the antenna from the physical environment.
• Voltage Standing Wave Ratio (VSWR) - used in the annex to describe input-port matching at the antenna connection.

Who uses SIST EN 300 631-1 V1.1.1:2003?

SIST EN 300 631-1 V1.1.1:2003 is used by antenna manufacturers, radio relay system designers, network operators, equipment purchasers and test laboratories. It also matters to regulatory authorities and spectrum planners who need antennas suitable for frequency coordination.

The foreword and scope show typical applications in local, regional and national networks, mobile base station connections, customer access links, telemetering and telecontrol, including transportable and offshore use. In practice, users rely on it to select antennas, compare class performance and check whether a design fits the intended interference environment.

What changed in SIST EN 300 631-1 V1.1.1:2003 from the previous edition?

SIST EN 300 631-1 V1.1.1:2003 comes from ETS 300 631, which was split into two parts. Part 1 covers point-to-point antennas, while part 2 covers point-to-multipoint antennas.

The foreword also states that the 3 GHz upper limit was introduced with reference to WRC-95 Final Acts and CEPT Recommendation T/R 13-01.

Which standards are used with SIST EN 300 631-1 V1.1.1:2003?

SIST EN 300 631-1 V1.1.1:2003 uses these references for its band plans and channel arrangements:

• CEPT Recommendation T/R 13-01 - preferred channel arrangement for fixed services in the 1-3 GHz range.
• ITU-R Recommendation F.746 - radio-frequency channel arrangements for radio-relay systems.
• WRC-95 Final Acts - background for the upper band limit mentioned in the foreword.

These references tell the reader which frequency framework the antenna requirements are built around.

What does the SIST EN 300 631-1 V1.1.1:2003 document contain?

SIST EN 300 631-1 V1.1.1:2003 contains the class-based radiation pattern figures for the three antenna classes, plus a separate elevation pattern for class 1. It also includes tables for minimum XPD and minimum gain, which are the key numeric checkpoints for design and type testing.

Annex A adds informative guidance on environmental exposure, wind survival, antenna stability, connectors, VSWR, inter-port isolation and labelling. That annex is useful when specifying hardware, writing purchase requirements or preparing installation and acceptance tests.

Annex B provides a bibliography for related connector and antenna references.
