The Southern Ireland Repeater Network is made of seven interlinked repeaters on 2-metres and 70-cms and covers the southern half of Ireland. The coverage map as of June 2020 is shown below...
There are now plans to fit a new 70-cms repeater on the summit of Mahera in Co.Clare in the west of Ireland. This is an excellent site in terms of coverage and is one of the main transmission sites used by the state broadcaster RTE for radio and TV.
An approximate coverage map of the new proposed 433 MHz repeater is shown below....
The most significant change is that it will add Galway City to the Southern Ireland Repeater Network which is a welcome development.
The eastern part of Limerick City should also be covered although Woodcock Hill will screen signals to the western part of the city.
The coverage map also suggests very good coverage of the main road from Limerick to Galway as well as the eastern part of Co.Galway and the part of the midlands.
From my understanding, the new repeater will be installed once the travel restrictions for COVID-19 are eased.
