Radio Link Antennas Definitions
Gain (G): The ratio of the radiation intensity, in the main beam axis to the radiation intensity that would be obtained if the power were radiated isotropically. Value measured in dBi. Half-power beamwidth (HPBW) or 3dB-beamwidth: The angle, relative to the main beam axis, between the two directions at which the measured co-polar pattern is 3 dB below the value on the main beam axis. Half-power beamwidth (3 dB-beamwidth) -3.0 dB

RFS Microwave Antennas Survival and operational windspeed, definition
Antennas withstand specified survival windspeed without any permanent damage!
Antenna axis deflection is less than one third of half-power beam width at operational windspeed!
Radio Link Antennas Co-polar radiation pattern with RPE and F/B-ratio Front-to-back-ratio (F/B): The difference in dB between the co-polarized main beam gain and the signal measured in a defined region back to the main beam.
F/B
Radio Link Antennas Cross-polar radiation pattern with XPD Cross polar discrimination (XPD): The difference in dB between the co-polarized main beam gain and the cross-polarized signal measured within a defined region.
XPD
Radio Link Antennas Contour plots, co-polar and cross-polar
Co-polar pattern:
A diagram representing the radiation pattern of the antenna under test when the reference antenna is similarly polarized, scaled in dBi or dB relative to the measured antenna gain.
Cross-polar pattern:
A diagram representing the radiation pattern of the antenna under test when the reference antenna is orthogonally polarized, scaled in dBi or dB relative to the measured antenna gain.

Radio Link Antennas Return loss, reflection coefficient and VSWR Return loss:
The ratio of incident to reflected power at a reference plane of the network. r = -10 log Pref / Pin [dB]

RFS Microwave Antennas Increased Windload Kit, example 1.8 m antenna
Large RFS antennas (1.8 to 3.7 m) already incorporate a strong back ring structure to support the reflector. The hot dip galvanised steel mount is fixed to the back ring. This configuration allows a simple upgrade of one of the antenna’s most important mechanical features. The Increased Windload Kit of additional struts for mounting between the back ring and the reflector rim. Thus enables the wind forces to be directed to the most rigid part of the antenna mount. The kit can be installed on site before lifting the antenna onto the tower.
RFS Microwave Antennas High Windload Kit, example 3.7 m antenna
The kit 270 km/h for 1.8 m to 3.7 m antennas consists of: Increased windload kit and 3 additional sway bars (dia. 60 mm, length 3.0 m) fixed at the rim of the reflector.
RFS Microwave Antennas High Windload 1.2 m antenna
The 1.2 m antenna for 270 km/h consists of: Reflector with backring and a sway bar (dia. 60 mm, length 1.50 m) fixed at the mount

RFS Microwave Antennas µ-wave Link Calculator, introduction
The power level available at the receiver is calculated based on specific system parameters • Transmitter output power [dBm] • Frequency [GHz] • Link distance [km] The calculator takes into account: • Free space loss [dB] • Rain attenuation [dB] • Atmospheric attenuation [dB] • Polarisation • Antenna gain [dB] • Loss in feeder or Twistflex section [dB]
http://www2.rfsworld.com/mwave
RFS Microwave Antennas µ-wave Link Calculator
Three different installation cases are considered: • Radio integrated with antenna The radio unit is directly mounted onto the back of the antenna. This is a very common type of installation avoiding additional loss in feeder or twistflex sections. • Radio near to the antenna In cases where the radio can not be attached directly to the antenna, an additional section of twistflex provides the connection to the radio. The radio is installed on the pipe or tower near to the antenna. • Radio in a shelter In traditional backbone systems as well as in configurations where quick and easy maintenance is required, the radio is installed in a shelter at ground level. In such cases FLEXWELL Elliptical Waveguide (feeder) provides a low-loss connection to the antenna.

RFS FLEXWELL Elliptical Waveguides Product Portfolio
Three versions of FLEXWELL® elliptical waveguide are offered: • FLEXWELL® “Standard” waveguide, 1.7 – 39.5 GHz • Low VSWR “Premium” waveguide, 3.0 – 19.7 GHz • “Overmoded” waveguide”, 10.7 – 39.5 GHz Standard and premium waveguide differ only in testing and guaranteed attainable VSWR. FLEXWELL® “standard” waveguide is recommended for low and medium capacity radio relay systems, while FLEXWELL® “premium” elliptical waveguide assemblies are recommended for high capacity radio systems. Overmoded waveguides offer exceptionally low attenuation characteristics compared with conventional waveguides. The waveguide operates above the cut-off frequency of higher order modes utilizing the lowest attenuation characteristics of the waveguide.

RFS FLEXWELL Elliptical Waveguides Connector with ‘Plast 2000’ sealing
Plast 2000 Sealing Plast 2000 has a very good adhesion to the metallic parts of the connector and to the waveguide. The curing process depends on the humidity and temperature of the air. Under normal conditions, sealing against moisture is accomplished in a very short time. These connectors have been carefully designed for excellent VSWR performance without the use of any tuning screws. Model numbers on these connectors end with a letter “P” to designate the use of Plast 2000 sealing. Exception all connectors with gasket and shrinking sleeves: E250 and E380 series, all overmoded waveguides.
RFS FLEXWELL Elliptical Waveguides Connectors, gasket sealing
Gasket Sealing In this design, the connector is sealed between the backnut and the waveguide with a conical shaped threaded gasket. The threaded gasket is held in place with an internal pressure plate to create a gas tight waveguide assembly that will not leak even if the waveguide is flexed near the connector. A seal between the connector backnut and the waveguide transition is achieved with a specially shaped flat gasket that encompasses the waveguide flare and connector bolt holes. A heat shrink boot is supplied for application over the elliptical waveguide and the connector backnut to provide strain relief and additional weatherproofing. Model number on these connectors end with a letter “G” for designation of gasket sealing.

RFS FLEXWELL Elliptical waveguides Dehydration with dehydrator
-
Both ends of the waveguide run are closed with pressure windows (or at one end by the pressure tight antenna). The dehydrator is used to remove any moisture from the system.
-
Different dehydrators can be used, but the maximum pressure of 0,3 bar has to be kept.
-
The max. length of waveguide is dependent on the capacity of the dehydrator

With metallic case for wall mounting
ETSI-N3 brackets
Attention: Because of humidity coming out on top of the equipment during regeneration and the high temperature (100°C) leave an upper free space of at least four units from the dehydrator to the closed equipment!

RFS FLEXWELL Elliptical waveguides Dehydration concept for small volume waveguides
The closed system with purging, seal test and humidity indicator
-
Both ends of the waveguide run are closed with pressure windows (or at one end by the pressure tight antenna).
-
The system is purged with dry nitrogen (5.0) and seal tested after installation – with a transportable purge and sealing device. Moisture is eliminated from the waveguide.

Purging and seal test
Attention: The max. pressure is 0,3 bar!
-
In case of leakage the desiccant cartridge will provide an early warning (changing colour from blue to violet). The maximum length of waveguide is determined by the size of the nitrogen bottle.
RFS FLEXWELL Elliptical Waveguides Transportable purge and sealing device
The RFS purge and sealing device can be used up to a waveguide volume of approx. 2 litres:
