4.1.3 Transmit/receive centre gap
The centre gap shall be taken as a multiple of the basic raster distance of 14 MHz, and shall not be
greater than 70 MHz.
4.1.4 Transmit/receive duplex frequency separation
The transmitter receiver duplex frequency separation shall not be less than 500 MHz. (Typical separations
will be around 1 000 MHz.)
4.2 Compatibility requirements between systems
In order to provide compatibility between systems there should be no requirement to operate transmitting
equipment from one manufacturer with receiving equipment from another.
4.3 Types of installation
The equipment may comprise both radio relay units in weather protected locations, and outdoor units with
the Radio Frequency (RF) assemblies located close to the antenna in order to minimize feeder losses.
4.3.1 Environmental conditions
The equipment shall be required to meet the environmental conditions set out in ETS 300 019 [3], which
defines weather protected and outdoor environmental classes and test severities.
4.3.1.1 Equipment within weather protected locations
Equipment intended for operation within temperature controlled locations or partially temperature
controlled locations shall meet the requirements of ETS 300 019 [3] classes 3.1 and 3.2 respectively.
Optionally, the more stringent requirements of ETS 300 019 [3] classes 3.3 (non-temperature controlled
locations), 3.4 (sites with heat trap) and 3.5 (sheltered locations) may be applied.
4.3.1.2 Equipment for non-weather protected locations
Equipment intended for operation within non-weather protected locations shall meet the requirements of
ETS 300 019 [3], class 4.1 or 4.1E
Class 4.1 applies to many European countries and class 4.1E applies to all European countries.
Weather protected equipment conforming to classes 3.3, 3.4 and 3.5, together with an enclosure or

cabinet may fulfil the requirements of operating in a non-weather protected environment, but this is
outside the scope of this ETS.
4.3.2 Electromagnetic compatibility
Equipment shall operate under the conditions specified in ETS 300 385 [13].

4.5 General characteristics
The following characteristics are desirable:
- tuning facilities;
- flexibility for location of systems;
- wayside traffic facilities;
- transmitter identification;
- maintenance facilities;
- performance monitoring facilities.
4.6 Transmission Management Network (TMN) interface
Any TMN interface required should follow CCITT Recommendation G.784 [11] and ITU-T
Recommendation G.773 [14]. This subject is also under study in ETSI TM 2 and TM 3.
4.7 Branching/feeder/antenna requirements
a) the minimum recommended antenna radiation pattern envelope is shown in figure 2, element 2A. It
may be necessary to use a higher performance antenna pattern as shown in figure 2, element 2B;
b) antenna flange/equipment feeder flange. When flanges are required, IEC type R620 should be
used.
